Just found your channel (and subscribed) - very interesting and informative. I've only heard Magnepans 1 time, back in the early 80's if I recall correctly, they totally blew me away. I've wanted a pair ever since but circumstances have never worked out. Might be able to swing a pair of LRS's someday - fingers crossed. Kudos on your channel & videos.

I did a similar thing with my Totems when I was using a st70 tube amp . I used a rca high pass filter to make the same goal. Works well and is easy to use.

@donaldmeger8832 2 года назад

The ideal subwoofer setup for open baffle speakers like Magnepans are open baffle subs. My favorite of these by far is the Linkwitz W frame design (on his site). My second recommendation would be to go with a sealed enclosure subwoofer. In ALL cases, the subwoofer amp should have variable phase control for proper integration. Find the F3 of the main speakers ( F3 is the -3db response point) multiply by .71 to calculate the high pass F3 frequency for the subs. The Magnepans (open baffle and sealed enclosure speakers) will drop 12db per octave below F3 therefore the low pass filter for the subs should be 2nd order butterworth (most commonly applied with powered subwoofer systems). I recommend to NOT apply a passive high pass passive crossover in front of main speakers. It is better to have an acoustic transition to the subwoofer (as I previously explained). THEN you can also apply a simple 1st order subsonic high pass filter by inserting a film capacitor in front of the speaker's power amp (if you can). The F3 of this subsonic filter should be at least 1/2 octave lower than the acoustic F3 point. F=1/(2*pie*RC) where R is the input impedance of the amp. This way, the subsonic filter is not greatly affecting the overlap of the speakers and subs. For example, an amp with 47k ohm input R would need a .1uf cap in series with the positive lead that goes from preamp to amp to get a 1st order high pass at about 35hz. This is far enough below the acoustic F3 of the LRS. The benefit here is that the amp will not supply very deep tones to the speakers that makes them vibrate yet are not heard. This will lower intermediate modulation distortion which is one weakness of the LRS design. Subwoofer placement is all about the math of the room. A corner placement is usually the BEST default placement for a single sub because it best avoids room nodes. But that may be bettered with experimentation. If you do want to apply a passive crossover for your main speakers, the F3 of the crossover should be at least 1/2 octave higher than the F3 of the speakers. Don't use electrolytic caps. The expense of building or buying a pair of decent low frequency passive crossovers approaches the cost of an active crossover and amp combination.

I do something similar with my .7’s, Goldenear Triton 2+, and Parasound Halo integrated (model just before Halo 6). I use the sub out on the Parasound (it’s stereo summed to mono), set the crossover to 100Hz, rca cable to the LE in on the Triton’s, which have their own DSP controlled, built-in subs. I did check with both Parasound and Goldenear to ensure the logic was sound and they agreed. Saved me having to purchase separate sub(s) for the .7’s. And this set up does exactly what I wanted: rounding out the bottom end a bit. I only use the Maggie’s for classical, so there isn’t a lot of heavy bass work anyway, but I always felt I was missing just a bit of something with things like contra bassoons.

@nickparkin8527 3 года назад

Nodes are the result of the fact that bass wavelengths are too large to fit in your room, so they reflect back constructively/destructively interfere with themselves creating nodes. You cannot minatureuze a sound wavelength. 20hz is something like over 70 feet long.

@mikw1809 3 года назад

@@nickparkin8527 "Put your sub where YOU sit and walk around and listen to where the bass sounds the best. Mark that spot with an x and put your sub in that new location and you’ll have great sound." Can you explain why your "great sound" solution works? Can you provide the math to explain what is happening that constitutes an improvement in sound quality? The problem I perceive is that my ears are not 2 inches from the floor where I sit, and my sub faces down, but not all subwoofers do. If I move a speaker even one inch from it's position or move my microphone more than an inch from it's measurement location, I get a different frequency response. With EQ done correctly, I am able to get a much flatter response in bass. Who said anything about using software for EQ? I only use software for capturing the frequency response, the concept of using EQ is nothing new, sound engineers have been doing this since the 1930s. Every loudspeaker uses EQ via a crossover, and may contain a notch filter to tune a problematic range of frequencies that may be attributable to the loudspeaker resonant frequency or cabinet design. The room is no different to a speaker enclosure in that sense.

@mikw1809 3 года назад

@@nickparkin8527 "You cannot minatureuze a sound wavelength" Yes you can.. by reducing the gain of those frequencies before amplification ( in practice you reduce or increase the gain of a range of frequencies ). If that's not possible, then you need to let companies like Kef know that their Kube used in their legendary 107 that allowed Q and contour adjustment was a waste of time, and all the other manufacturers of equalisation / DSP products ( Technics / JVC /Behringer ) must have been selling fake products?

Full control over the low pass signal as well as much faster pass to match the high speed of the Magnipans. Just my two cents…😜👍

Hi. Good video. I will watch your other videos. I have a pair of the Magnepan 1.7i. I have the MyeStands from Grant Vander Mye in Canada. I also have the Mike Powell Ag upgrades (replaces the fuse with a silver tube and the stock plate steel jumper with a silver one) and a pair of REL T/9i subs in a 2.2 configuration. The first two mods were significant improvements. But adding the RELs revolutionized the SQ and added air moving sub bass that the Maggies just can’t do. I have had no issues with the silver tube instead of the fuse. Just be careful as usual in how you turn on and off your preamp and amps and everything will be fine.

@travismcgee100 2 года назад

At 3:40 you mention an eight week backlog for the Magnepan LRSs. When I ordered them in September, 2021, I had to wait five months to get them. At that time I paid $650 plus shipping, but I believe the price in April, 2022, is $750. I love the LRSs but I knew almost immediately that I would need subwoofers to be happy, so two days after the LRSs arrived I ordered two REL T/7x subwoofers (I wanted front-firing subs) on Amazon at $1,000 each. Both the LRSs and the T/7x (actually the T/7i, the earlier version) were in the Absolute Sound magazine list of "50 Greatest Bargains in High-End Audio." I am extremely happy with my system; it sounds fantastic. Ironically, the least expensive part of my system, the LRSs, drove the decision regarding the purchase of every other bit of gear--except the phone--in the front end, and every piece is more expensive than the LRSs. The front end is: RU-vid Music on a Google Pixel 4a phone to 10' USB cable to Schiit Bifrost 2 DAC to Schiit Freya+ preamp to two Schiit Vidar amps as monoblocks. I am using the RELs in High Level mode when attaching to the Vidar amps. With the Schiits, the RELs don't get any hum so I don't need a ground; the black wire is just left hanging (covered by electrical tape). When I switched the speakers and subwoofers to my Yamaha AV receiver to try them in a TV theater setup, I got a lot of hum, so I attached both black wires to the phono ground on the back of the receiver.

@@Munakas-wq3gp Omnidirectional does not mean magic. Yes, the low frequency wave will reach me at some point in time. Don't we want it as time aligned as possible? If I put the subwoofer 100 yards away from my mid-range and tweeter will that affect how the music sounds? I am guessing it will, so now we are talking about what degree of "misalignment" we will accept. I will take the front-firing subwoofer and pretend to myself it is working better than down-firing only. Save yourself some money and get the down-firing only version. Don't be a fool such as I.

@@travismcgee100 A 20hz wave is 17 meters long. It makes zero difference which way your woofer points in a 2 by 2 foot sub box. The bass waveforms are so long that your ear loses the ability to detect the phase (and direction of sound) around 80hz and lower. At that point it makes zero difference which way your woofer points at as long as your sub is correctly in phase with the rest of your system.

@@Munakas-wq3gp Just to be clear, don't you mean "near zero" instead of zero? In a single small source, does distance make zero difference or near zero?

I am interested to know how much money I wasted.

@Munakas-wq3gp 2 месяца назад

@@travismcgee100 I mean zero difference. A human ear can't tell the difference in time or direction once the wavelength exceeds the distance from ear by a set margin and the room modes will cause significant disturbance... Only a microphone can pick it up and even that won't pick up a difference regarding to the face of the driver if the driver is correctly aligned with the rest of the system. The key here is correct alignment - if your sub is in correct phase it doesn't matter if it points up, down or sideways. It radiates omnidirectionally. The only scenario where the direction can be audible is if your sub is not actually a sub and radiates also midbass. You don't want that in most cases though. You'd need to have a stereo pair of 'subs' in order to maintain a stereo image for starters.

@peerguy 3 года назад

I am waiting for my LRS to ship and ha e researched a ton on crossover. It is recommended to crossover around 50-60hz if your processor / receiver can do it. It’s below 50hz where it gets distorted and can easily do 60hz. Obviously try it and let us know what worked for you and your room.

@DIYHiFiLife 3 года назад

Keep in ming that an 80hz High Pass Filter will actually start to effect higher frequencies such as 100 hz. I think 80hz is a good starting point and is a standard across the industry.

@Munakas-wq3gp 2 месяца назад

50hz is the maximum crossover frequency that works in a typical room. A sub is not a midbass. If you have 3 or more subs then you can get even higher cutoffs working. Above 50hz the sub will start to localize which will effect the stereo image (and often room modes are 80-100hz which should be avoided)

Instead of using fuses (any kind) to protect tweeter/or any drivers you can put in parallel to the driver a couple of zener (back to back) of the right voltage (based on the driver specs) so no additional component will be on the signal line.

I installed the fuse bypass kit from Mike at OCD, it is a silver bar cut to size and filled with an anti-resonance material. I’m sure I experienced burn in when adding the bypass for a few minutes I thought something was wrong as the top end didn’t appear to be there and then it came through after a few minutes. I did have to get pliers to squeeze the fuse holder terminals close together for the LRS. I think I’m hearing a difference, but will need to switch back to the stock fuse to confirm. I have the same stands, very nice indeed and the couple who run the business seem very nice too. Did you try the jumper cables out? Mine are still sealed, I wanted to experience the upgrade of the stands on their own, so didn’t add the jumpers and forgot about them. I already had Kimber Kable 4TC jumpers installed already. As for subs, I went down the 2 x SVS SB-1000 route. I have them tapped in to the speaker posts on the Hegel Röst amp as Paul McGowen recommends. I did see OCD Guy’s video on how he uses active crossovers, I did look in to doing the same, but I think I needed separate Pre and Power amps, so wouldn’t work with my integrated amp.

Whether the tube of the fuse is glass or ceramic, the wire inside is the same, as are the Brass endcaps - Brass is awful for signal transmission as it contains so many impurities. So, I would say 'expectation bias' is firmly at play here! Sub Position - if I do as you recommend and place my T9i in the centre of the room between the speakers (1.7i), then I get very little added/perceived bass at the seated position. Right next to, on the inside, of one speaker gave acceptabe results, but not visually or for convenience, as I had to step over it all the time, but then spent two days experimenting a good position, which I found to be at the opposite end of the room - almost, but not quite in the corner, about two feet out, at a 45° angle, which put it in the same plane as the listening position, in my 22' x 16' room, with a 9' ceiling.

@DIYHiFiLife 2 года назад

Thanks for watching. Sub positioning is one of great audiophile indoor sports. At least by separating out this frequency region you have the flexibility to experiment. Some feel a number between 2 or 4 subs in a room is ideal. WRT, fuses. As I said some believe the best fuse is no fuse but it voids your warranty.

Instead of fumbling with alternative fuses : remove the panel on the back and place the connector/wire of the jumper on the + side and mount it together with the + connector. Now you bypass all the restistance of the fuse and jumper. Can be done in 10 min with a screwdriver and spanner.

Thanks for watching. You could do as you suggest but it would void your warranty. I wanted to give people and option that allow some experimentation but was easily reversible. Ideally, MP would recognize that everyone uses subs with their speaker and build in a high-pass filter directly into the speaker.

@slimshady9203 2 года назад

What about the BIC F12 subwoofer over the Emotiva SE8? I believe it also has a high pass filter according to the manual's description of the crossover. Great video by the way!

@DIYHiFiLife 2 года назад

Thanks for watching. I looked up the specs on the BIC F12 but couldn't determine if it had a high pass filter. If it does you are good to go. Otherwise I still believe the Emottiva is a good value way to go.

@kozmiczian Год назад

Its a high pass filter . . . get the 100hz model. Rolls off lows from below that, so the mains dont have to stress to repro 30hz notes. The filter, in my modest system, works well. The amp cruses in this setup . . . caveat, you must use a self-powered sub.

Have any of you actually upgraded / modified the passive crossover using better parts / values? If so, what did you do? How did it improve their sound? Can the "active crossover" be used to replace the internal stock crossover? If so, what did you do and how did you do it? It would seem that you could use an active crossover to connect to each of the two mid & treble panels, while bypassing the bass to REL subs that would allow tuning of the crossover points. Has anyone done this? If so, what did you do and how did you do it?

@ericelmore2742 Год назад

Since posting this video have you finalized what modifications you have stuck with for best results

@nntexperiences5364 2 года назад

Nice video! I think you will be better off by using an active crossover. What you did is theoretically correct, but you are adding more components between the amplifier and the speakers( the speakers also have their own passive components) which wastes more energy from your amplifier. In other words, the overall sensitivity of the speakers are reduced which make your amp more difficult to drive the speakers . Furthermore, the signal will be smeared slightly to heavily by that passive high pass filter. From what I see, those are cheap electrolytic caps and iron core inductors which I am 100% sure they will take out some certain level of clarity of the signal from your amp. If you try back and forth with some songs that don't have low bass, you will get what I mean. Thanks!

@kozmiczian Год назад

His filter he's showing is a high pass filter, don't misunderstand, it only affects lowfrequencies. Iron core inductance, and electrolytic caps will not influence the souund as much as in the highs. Put the filter in line, from your subs outputs, to filter, to inputs of mains (direct wired, soldered). It passes all freqs, above 100hz, to the mains . . . and dead ends everything below 100hz. Freqs above 100hz pass directly to mains without passing the high pass filters circuitry. Works like a charm, makes my inexpensive Micca RB-42s sing like LRS s. 😊

I can confirm a sub is a must with these speakers I went with the Adam T10s, because Adam make fantastic studio speakers which I have experience with, so this is a studio sub but it works perfectly for home cinema and hi-fi, it has 2 selectable high pass frequencies, it will also take RCA or XLR balanced, it ticked every box for me. Plus having the ability to set your bass gain independently from the speakers is great as I tend to keep my bass low, not over powering or unnatural

@rudi_nieuwenhuis 2 года назад

Ok, maybe it's because I wrote in Dutch before. Let's try English: You CAN get the LRS for 1090 in the Netherlands now since a couple of days. It's true that there used to be a Dutch distributor that added a hefty margin so they would cost 1450 here. But after some emails with him where he told me that he has been making his money like that for 35 years, I contacted Magnepan directly. They were not amused by this and took care of it straight away. Now the European website (run from Sweden) gives you the option to ship to the Netherlands as well. Germany was already on the list.

@JohnLee-db9zt 2 года назад

I see the point of trying to relive the LRS from low frequency duties with addition of a high pass filter. The problem with adding a high pass filter is you’re adding more sound degrading components into the signal path. Moreover, that particular filter is made from some of the worst inductor (iron core) and capacitors (electrolytic) for audio quality. I prefer to run the LRS full without a filter with a subwoofer.

I think it's funny to note the meager fuse wire supplied (and found satisfactory) by the makers of Magnepan is being questioned. Yet our enormous overkill speaker cables, are not. Our expensive cables must be right (perhaps to justify the cost) so the fuse must be wrong. Thinking outside of the (speaker) box imagine producing a new line of ultra thin speaker cables (could still be expensive, 😉) that everyone must now get to correct their systems.

I would like to hear & try Maggy's LRS's but there is no dealer who "has them in to hear or can get them ...unless you want to pay first!. After owning many diff' e/stats, (& box speakers) ...i'm kinda addicted to the box'less sound of panels but i've never owned full'range ribbon like (the now'gone Apogee's or) the Maggies before. The LRS size implies there's going to be a shortfall of frequencies below 200 or maybe 300 Hz, (theoretically, on baffle width) from my e/stat experience, where subwoofers dont go, my REL Q-400 goes to 110'Hz top frequency & never helped any of my e/stats beyond superficially with home-cinema but music is my only prime hi-fi goal & the REL never musically "gelled' when they lacked output below 2 or 300'Hz ...the 'richness zone & mid bass-punch area. Do LRS go that low without being 3 or 6'db down? ...i never could find that spec'. When i checked u.k. prices when these LRS's were 1'st getting glowing reports, i was ready to buy "blind" untill i saw that we English get totally ripped-off by some entrepreneur importer or dealer with 50% mark-up of U.S. prices inc' delivery mark-up (surely theyre not that huge & heavy when packed for a £4 - 500'ish added del' charge to u.k.!) I was quoted various o.t.t. prices between £900 & £1200 all-in, for 1 (one !!!) pair of LRS. If i could get tham at U.S. prices of $650 per pair (450'ish £G.B.) i would deffinately buy 2 pairs & have the 2'nd pair with an adjustable low-pass filter added before the input sockets & have each 1 of those stand flush next to the untouched LRS pair ...for a +3'db gain below some adjustable frequency that sounds best (low-pass upto 250'Hz i reckon by width) that's if i could them at your price, you lucky U.S.'ers with yer 650 dollar LRS's with amazing reviews, I'm not jealous, just extremely annoyed by human greed & no Maggy dealers in UK for LRS, just folk ready to charge me 2 or 3 times the price i could maybe import the myself, i shall look into that now i thought of it

@todddembsky8321 2 года назад

Never, Never, NEVER remove the fuse. The Magnapan is a very high current speaker and the tweeter wires are very small gauge (like 22). If you want high volume, the Magnapans are not efficient (like 86db) so to get to 100 DBA in the room, the tweeter wires are going to get hot from the amount of current you are pushing. The tweeter wires will get hot enough to separate from the mylar and start to buzz and rattle. That fuse will give you that extra protection to save you from needing Magnaplaner to refurb your speakers. $20 is a whole lot cheaper than just the shipping of the speakers. Subwoofer -- I run a 12" 1000 watt sub, I set the cross-over at the sub to be 80hrz. The high pass filter I also set at 80hrz, however, I run a second-order 24db / octave roll-off. I want to get the magies to roll off as fast as possible. Room coupling -- 300hrz wavelength is 1.4 meters, 400hrz wavelength is .84 meters. In a three-meter room (or ~10 ft) 300hrzwill have a full-wave length of 5.5' -- 400hrz will have a full-wave length of 3.2' -- both of those frequencies will give you a standing wave in a 10 to 12-foot room length. The male voice starts at 300hrz and goes up. Remember that A4 is 440hrz. As such 300 - 500hrz is a huge problem area for the creation of standing waves and nulls. I have a pair of MG1's "Early 80's" and I love them. Do not expect punchy bass, but do expect pure mids and highs. I drive them with a Yamaha B6 200-watt amp. These were made 2 years before Carver enforced its patent on X circuit topology.

@@bryfar6178 I use the 3A normal blow (not fast blow) fuses for my MGI. These are from 1980, and are 6ohm speakers. I blew the fuses at almost every party I had in College. Got tired of replacing fuses, so I wrapped one in tinfoil, then the tweeter got so hot that it melted the adhesive on the mylar and made a wonderful rattling sound. Wonderful speakers, excellent voicing, no bass under 100 hz, so I backed them up with an MK 1000 watt 12" sub crossed over at 150 hz. Good luck finding your fuses, If you can find a 3amp fuse, the fuse will blow before the 4amp fuse, however, those should be easier to find and will blow before a 4amp will, so you will not be able to run as much amperage through them.

I have everything below 80 cycles going to two pairs of public address woofers mounted open baffle solo baric and right next to and on the exact same plane as the Magnepan and it is better than the Rels I tried and the M&K I’m pretty sure the lack of a box as well as the di pole approach is the reason why it is not noticeable at all Its the best blending I’ve seen Steep slope and your going to be much happier The concept is more of an open baffle than a subwoofer And I am delighted with the results I got all my drivers from church upgraded sound system And the amps are the new crowns with the higher damping factor and I believe you will be amazed how the bass doesn’t sound like a box I think it’s the pressure and the di pole But I would bet if you could mount it on an exterior wall and lose the back wave it would still sound better than a box Try it out
