Wow, that is easily the best and most informative audio video I've seen on here. From the top quality info to the well made graphics. This man knows his trade.
Holy shit. I feel like I just had a 1 hour lecture in 7 minutes. Lots of great information. Looking forward more of these informative videos. Thanks for sharing & keep it up. To take things a step further, some math formulas or guiding principles to help out with designing enclosures would be greatly appreciated.
Wow, awesome stuff here. I definitely subscribed. Would you be able to make a video on the basics of how to build a subwoofer enclosure? :) For example: A driver with these specifications + These expectations in terms of frequency response and application = This is how to design the best enclosure. Because when i look around, i can find tutorials or guides but it's just like, you have these specifications, run it through this program and there it is. But i want to know why we choose a port width, length, box size, ... So i can take that knowledge to the next project. I think i understand the basics, however it's sometimes very confusing. But for some reason i immediately understand everything you explain.
Was waiting for him to either open his eyes or play the keyboard the whole time. Just had an idea for a speaker box design though so I thank you very much.
I have commented before and I will again, this is the guy to listen to and watch. I am also a guy who knows this subject matter for many years oh, so I can tell you for a fact that this guy is good. The level and execution in which he explains things is superb. He doesn't just recycle and regenerate the same generic stuff over and over as do most of the videos on audio. I also respect that he said that he is still learning, because that shows intelligence instead of arrogance. I have over 20 years experience myself, including a MECP, and I'm also always learning new things. I like watching his videos for these reasons and or even just to touch up on a few things. Then again when I'm out in the shop, I'd rather watch this type of thing then Keeping Up with the Kardashians or some nonsense.
"Took me 20yrs & I'm still learning." Thats a true audiophile. If actively seeking out new knowledge, insight, & data ISN'T where the bulk of your time 'doing audio' is spent then you're not an audiophile. Sorry but it's tru.
My first subwoofer box was homemade with round nonflared ports. Nothing special 12 in woofers and a budget amplifier but wow. All about the round ports.
@@HexiBase Do you think that using a round port in a Voight pipe or ML-voight would make a diference? It seems that so many professional "youtubers" are using it. Thanks! You are the best! So Laconic..
you earned a sub for 3:11 😂it's refreshing to finally see someone bash that format of explaining or teaching concepts. also explaining so much in that first 3 minutes, in an easy to understand way.
Would love to see some explanations about complications from corners/bends in ports/horn paths. Your videos are great, I have learnt a lot from your channel!
Question....2 sundown x18v3....14 cubic feet box at 32 hertz.....can I use three 6 inch ports at 11.56 inches to reduce port displacement.....or do I need four 6 inch ports at 16.87
What about reversing tapers? Or what about reversed compound tapers, like a diamond shape with the tips cut off? Or even reversing flares, having a smaller opening that rapidly open to the port size? Or making a TL out of a compound taper? Or a TL-horn hybrid, where one section is straight and the other tapered, with both variations of flat first and tapered first? Or really any hybrid method of combining various port types? I have a lot of other ideas, but that's just a handful of them. I know these probably don't sound or work as well, but I want to see what unconventional methods accomplish, for science.
Pretty good... Maybe you should mention that a-periodic enclosures need to be ported outside of the area the speaker is facing. Its a little more than covering the port with cloth
Recently I built 4th order for 2 10" subwoofers, sealed was a little over 1cube, ported was 2.3cubes, I tried to tune it to 36-38 hz with 2 3"/8" flared ports didn't like the sound so I removed 1 port shorten the 1 port to about 4" it was worst, this was on a 3k, then I switched to a 5 k and that made matters worse, I'm going to scrap the box, but I think a box that small I had to tune it to more than 40hz, but I simply don't like higher tunings, I'm probably going to just make a regular ported box for those 2 10s
I hope you see this question ... You are the most knowledgeable person I have found on the web regarding subwoofer enclosure design so I have a question for you. I built a 6th order BP. I built it with the 35hz port facing the rear of the vehicle, and the 85hz port facing the front of the SUV. My thinking was the lower bass could bounce off the back to gain strength, and the upper bass could come straight at the front. It's loud and clean, but there seems to be a lull in the 60-70hz region, and I don't know if it's because the tuning is so far apart, or because the ports aren't facing the same direction. Please advise me Yoda🙂.
🔴I have a 8 cu ft gross ported box (with 15" kicker L7s 1000w) my port area is 17.5" x 4" equals to 70 in2 (or about 9 in2 per cubic foot). can someone tell me if my port is to small. i heard its supposed to be 12 to 16 inch squared per cu ft
I have two 600 RMS subs I bought from a guy trying to do a home speaker. I would like to use only the subs since the rest was crappy. They are Edge Hollywood ED-1596. I can't find the specs and I'm wondering if it's too big to use both in my house (i gotta say I like it LOUD). Or to keep one for my car. What's your opinion on the subject?
Whaaaaaaa.....? I'm so confused. My brain hurts. I would have loved examples of all of this in real audio examples. Like discuss one theory then show it's example. The explanations are good but I can't grasp what it means in the real world.
Are there any special rules for PRs (Passive Radiators) such as where in the enclosure they should be placed (front, back, certain distance away from the active woofer...)? Also, is there anything special needed for an enclosure that has say 4 small identical woofers (let's say 8" or 10" each) with a big 15" PR? What normally should be the ratio of the PR's cone area vs. the total cone area of all the active woofers? Should the PR have at least the same area as all the active woofers combined (such as four 8" woofers vs. one 15" PR), or should the PR have more, and if so, how much more... 50%, 100%...? For a dual woofer isobaric (clamshell arragement) subwoofer, can a pair of PRs be added also in a "clamshell" configuration and is there any advantage to doing that? Thank you.
I think I just need invert my subs and take one speaker out to lower this SPL hertz, keeping my double ended flares in the back and enclosed 36x4 square box port in the front .. allowing more empty space inside the triple 12"ZVX D1vc.
Question to HexiBase: can I use multiple holes on the box, instead of a single tube? For example if tube required would be 10 cm long and 3 cm diameter, can I simply drill 5 pieces of 3 cm diamater holes on the front baffle which is 2 cm thick? I guess the resonating “airmass” would be similar. Yet no one uses holes! Why?
Stumbled upon your channel, finally i can learn something new after decades of loudspeaker building/interest! Thanks for your effort in making these videos! +1sub
Ports always bother me. I understand the resonance effect, but there are a huge number of internal reflections in a box which should cause a lot of interference patterns. So doesn't port placement, and/or wave path, have an effect on sound quality?
In my workshop i have a variety of loudspeakers - yamaha-JBL- court- and a pair of transmission lines - when it comes to bass extension and warmth the TL beat the modern 15 inch drivers. from 80m away you just sense the air is full of life- if you get time to talk about TLs , i would be an avid viewer. thank you
Hi I want to ask - how to limit my 50hz tuned speaker with 2 flare ports to say about 80 hz or considerably reduce lower frequency with out upsetting overall frequency balance? Will open cell foam reduce it like the foam used on classic spendor 100 speakers?
In rectangular slot port, the box walls are acting as port walls too, and they extend longer than port. So some people say WINISD shows upto 30% longer port length than needed. How far this is real ?? Any suggestions on this please ???
Bro I appreciate your time thanks. I have a 04 dodge Cummins 4 door do you think I would benefit from a bass tube or shallow sub? Also how do you feel about self amplified subs. Thanks
How about these ported boxes with a corner port where you can see it stops a certain distance from the back wall of the box . The triangle port would be different from square or rectangle but still no we’re close to the round . I just wondered if you had seen this and inside they have like half walls . I’m wanting to think there bracing but if you look at them the rear part of these boxes are angled down in the back like the top is narrow from front to back. So there’s 2 walls-braces best I can tell by looking at them 1 is up and down out maybe 2-5 inches and it’s closer to the back wall and the one off the back wall is wide at the bottom because the angled back and placed close to the side off center we’re the one is at. Then they are both on the opposite side the port is on at the bottom now that what I see if it’s a single driver the one I seen with 2 has got 2 triangle vents for each driver and dose not look to have those braces-walls in it . I kinda think they could be for we’re is a port the opposite side of them there for like air control ? There’s always something new or a twist on something we already have seen or hybrid of it . Also what do you think about the round subwoofer boxes I have seen them being made now we’re there ported different from back in the day . There measurements are off like the 10 ported is under a cubic foot so most 10s take a cube or more then you look at the 12” tube and it’s like sealed numbers 1.4 cubic feet ported I’m like buy a set of 12” tubes and put 10s in them might work they give you no port volume or exact size. There partly round or rectangular with sloped sides. I like the looks of them but we know the wolf can come in sheep’s clothing but enjoyed the info great video keep control of the other Pete and thanks again
Funny! found this searching head porting, you would be a natural guru at building race engines you just explained the evolution over 100 years worth of fluid dynamics under 10 mins
So looTell me more about the Heil tweeters on the ESS classic speakers will you. Might be before your time :) but they used to be a think back in the day!
I would love to see a video where you make a pair of bookshelves with a like a $300-500 budget and have Zeos Pantera Review them against all his speakers, haha. That would me a great colab. The best speakers I've ever had and still use are the giant JBL 590s that a bought when they go on sale for half off at around $900 for the pair. Theyre giants and need space but theyre mainly for home theatre duties or blasting music and sound incredible. No buyers remorse on those. I also have an original pair of the Yamaha HS80s for Music Production before the went to the HS8 that I got from a buddy for $350 which was a quite the hookup. Those too sound great. After hearing Zeos talk about the OHM Walsh's that he has, I've been dying to hear the sound of an omni-directional speaker, especially at that level. It drives me nuts that omni-directionls are so rare in the market, especially for use as surrounds. You think an Omni would be amazing for that since it would disperse the audio nicely and be more vague so the ear doesnt "hear" the audio coming from the speaker in a manner it shouldnt, if you know what I mean. That why I have my surrounds against the wall but aimed up so the reflect nicely off the wall while giving a much bigger sound stage and your ears cant pinpoint the speaker.
I clicked away at the end, then came back because you asked me to comment. My comment is I love you! Also I have a 44 Trimaran sail boat I would like to get some bass out of that is using the body of the boat as the box. I wonder what a great a fun video that would be.
does anyone know if I could do a 6th order bandpass with a regular round port for higher frequency response in the secondary chamber but use a passive radiator in the primary chamber for lower frequency response and higher sound quality to create a "sealed" front chamber and a ported second chamber
God, would i give anything to have a custom 3 way set of large bookshelf speakers from you. Something similar to the Hivi 3.1a DIY kit but with an enclosure and drivers designed by you.
I have to admit, initially I thought you were high, as I could barely see your eyes. That all vaporized when you started spitting out the physics. This is obviously a passion for you and I encourage you to continue putting out videos like this. I honestly don't know what I would do with the information. I guess it satisfies a desire to understand design decisions made in commercially purchased gear. I certainly have the tools to make some of the designs you speak of. Maybe this will push me to experiment with my own designs. What was your field of study and do you have videos showing the construction process of some designs? Keep up the good work.
Can my port face straight out the back of my box? Basically pointing at my sub? So sub points towards front dash while my round port points towards rear trunk
if i have 18 "speaker .. how to calculate box volume and port volume ... according to the data available on the speaker ... and i want to use it for outdoor..thanks
Usually, when I see the name of video "The BEST Video EVER" immediately I change the channel, but this time it was a good video. The really good one Thanks
In a car, does the port location make a difference? Like a subwoofer facing forward and port facing the back. Both facing the same direction. Which would be louder?
I had a Bose bandpass in my trunk and when the ports were facing towards rear of the car it had more bass but when I had a sealed inclosure it didn't make a diff which way the speakers faced
Good overview, but there are some aspects you didn't touch on. Could you do a part two and cover materials and their effect on ported air velocity? Internal geometry, enclosure dimensions, etc
HI Hexi, i just found your old reupload video about fostex drives ru-vid.com/video/%D0%B2%D0%B8%D0%B4%D0%B5%D0%BE-k_Bp8dOsZE8.html and i wanted to ask maybe do you have schematics of these? or other info?
And this is why you’re the ONLY person I hire to design my enclosures! These other so called designers can’t even go into depth of why they send out what they sale to people!
@@HexiBase You'll have my business as long as you're offering your services, They have nothing on you except price, but you know what they say about that ... matter of fact i need to submit a design request for my new work vehicle as i need my usual

What software do you use to make the blueprint slides?
Yes and then you have to factor in the cubic feet of the enclosure based upon how much your subwoofers can move plus if you're really built in some serious to cubic feet of your vehicle matters to
If I wanted to do this professionally like him, what would the career field be called? And what should I major in or what specialized schooling would I need?
Watched this 3 years ago when I first started making boxes and kinda understood it but bow I feel this the only man I can listen too to reassure myself I’m doing everything right 😂😂
I´m really glad for this kind of videos from you, maybe you can make some video about your software you use to simulate the boxes? I´m just moving from basic BASSBOX PRO6 to LSPCAD 6.42 that can simulate a lot more than BB6... so just a video with insight into your software you using :-)
I’ve never commented on any video on RU-vid... I felt you deserved to know that this video and several other videos you’ve made are providing information that I have spent months searching for. Thank you, extremely impressive video, and awesome teaching method. I’m currently building boxes for 2 Fischer midrange home audio speakers... almost have all the info I need..
Where can you get aperiodic vents now? I used the pair I had in a recent build, but have no source for any more. P.S., I like other Pete! I asked you about a cabinet design in your last video, but saw the address I needed to use to contact you after the video. Then, I lost it. Damn! I still need some help, so if you could send me that contact info it would be cool as hell! I finally got my refurb done and I'm looking to. I've forward on my next design. The only thing limiting me in this build is that I already have a pair of drivers etc use as woofers. Thanks Pete!
This dude does not fuck around. Instant sub. I'll agree with what someone else said, I also feel like I just got a highly condensed lecture with no bullshit filler. Amazing video.
Thanks to this video, I finally found out what’s the name of the design I made 15 years ago and it’s nothing more than a T-line. That’s what I used to call it anyway but then lots of people have been telling me that it’s not a T-line and I always was confused to what the hell it was.
I like high info density videos like this, no drawn out introductions and repeating over and over or product placements. Greatly appreciated! 7 minutes well spent!
So... which would be best for SPL or someone that wants the "optimal" or "best config" for having a good quality bass sound, while having a strong SPL (basically, which would you recommend for the "best of both worlds"?)
