Question for anyone that noticed, How is the quality? Same camera used however I found out it was iMovie that was smashing the video quality all these years. Now using Final Cut Pro, And converting the AVCHD footage that was freaking the editors out
Yep - misalignment of drivers will cause phasing issues. Depending on how many degrees out of phase the LF driver is with the mid driver, the comb filtering at and around the crossover frequency could definitely be described as sort of a cheap reverb-like sound. In a live sound system, 5” might not make a huge difference (although in theory and good practice it should be compensated for), it will be more apparent in a near-field listening environment. You are hearing much more audio direct from the drivers, which are out of alignment. The waves don’t get the time to propagate and bounce around the room before your ear notices something is fucked up.
I was tempted to say comb filtering but Im not sure most people even know about that, I notice that effect mostly when people have multiple speaker cabinets piled up wrong, For some reason current PA cab manuals do not show that you have to pair up tweeters close, I have to run speaker delays at all kinds of events for live sound and work out the time alignment by measurement, especially between subwoofers that might be at the dance floor closer to the audience
Also the woofer is playing full-range (no inductor in the crossover to low-pass filter the woofer) which certainly doesn't help things either. That's probably the reason for the 12 ohm woofer and mid range, because both the woofer and mid-range are playing the mids, so their effective impedance at everything except the lows is going to be 6 ohms. Similarly, the mid-range driver is also playing the highs. Shit cost-cutting design really.
MGRU-vid Account Yep - those second order high pass filters are pretty useless... Especially with the alignment issues in these things. Oh well, cheap will do what cheap does
These are just cheap. I have some Aiwa speakers that have better components, but they don’t have the best of crossovers. It is just a capacitor in series as well as a coil in parallel with the tweeter. The woofer runs full range. I actually think my aiwas have some potential to sound good, better than some modern stuff.
Not that bad. But really they just seem to be a rip off of those old panasonic 3 way systems. Those actually had a dedicated subwoofer channel for the rear drivers aswell though. (Sa-ak45 to be specific)
I don't know if somebody mentioned this but the reverb effect could be that one of the drivers is connected backwards inside, making the sound to be out of phase I believe
I think the reverb you were hearing could have indeed been the distance between the midrange and the woofer if the woofer was running full range. On the other hand, I think it was more likely that cheap plastic back on the box where the midrange was located. That seemed thin and resonant, so it was probably ringing.
Hi Garret Claridge ) I'm from Ukraine, and i want say you: "thanks, Garret". I grew up with this channel. I watching you since 2010. I remember Mike, you blowing up speakers with he) I'm 17 and i want say: "thanks, Garret Claridge".
What’s with these 2000s speakers being so ugly? I have a pair of Panasonic’s and they have a similar woofer at the back style. They don’t seem to make any noise when I plugged one of them in. They also need to be bi amped it says it on the front but I don’t know why that would be a selling point
You can here the direction of a sound and then turn your head to that sound. You can do this becaurse the brain first here the sound with the nerest ear. And then later with the other ear. So yes this speeker setup is "bad"
Garret I reckon that reverb you heard was the midrange being backed directly onto that chip board backing with a plastic enclosure... Put some stuffing in there and I bet it'd have gone away. BTW been here since like 2010 and it's still amazing you do the same stuff. Appreciate ya
Yeah, You can sure tell when I quit drinking from my uploads ahah, I can't help but stay cool with all this wicked Canadian medical weed they have me on for years now
I just remember watching your old videos with my friend on a cheap little DELL monitor And then trying to blow speakers on this little subwoofer amplifier
they look a bit like the ones I got with my very old PANASONIC SA-AK 48 when in my teens. and the sound was good to me back then but now the speakers are really crap now owning far beater stuff. I just think it never really had good treble & highs.
You might be correct on the spacing if the woofers were letting mids through butt it's probably through the ports bouncing around inside. I kinda did like those though lol
I have bought some white van theater research 1620 speakers at a thrift store and the tiny ass magnet on the mid range read 12 ohms and the wannabe subwoofer read 45 ohms
I swear it's impossible to find any of those hideous late 90's/early 00's speakers without fake ones on them. Makes me wonder who did it first, because then every company realised they can scam consumers with fake plastic speakers!
All the ones I have do not have any weird fake things like that, You mostly only find that shit on the low end shitty ripoff ones, like this unit here was a total ripoff of a panasonic sa-ak33 I used to own, although funnily enough this system actually sounded BETTER than the panasonic 😂
Doubt the difference in distance is an issue. The delay would be less than 1 ms, and the frequencies at which it would be an issue, again only for phasing, would be > 1 kHz. As far as the sound goes, the only thing thats affected is the phasing, which is why good hi-fi units have the speakers in line so there are no phasing issues or differences in reflection of the higher frequency sounds that have wavelengths too short to be omnidirectional. More likely its a cheap cabinet or something. Edit: Doesn't help that theres no acoustical batting.
I remember this older technology from the 2000's. We had something like that in our family. So cheesy. But if I were to live on an island with only this system to use, then I'd stick with it. Better than nothing.
Hey Garret, I fixed up a system from the 1960s for my grandparents and they are 16 ohm 10 watt. But they were loud, I could use them outside and only need turn them up a little and they were blasting. I was wondering if you knew why they were so loud but only 10 watts? Thanks.
It's because of efficiency. Judging by other speakers from that time period, the speakers you were fixing up were probably around 101dB/w (but I could be wrong). Since I'm really bad at explaining things, here's an article about efficiency: www.lifewire.com/amp-power-speaker-efficiency-3135077
Also the woofer being driven basicaly full range it want to play the same material as the mid, but a few inches back. So you ear the mid first then the woofer.
Should really never hear that unless you are over powering a speaker........ but in some cases a speaker can be designed in such a way that they flex really easy and any heavy bass drop can cause that to.
@@CotyRiddle Such as a Bandpass enclosure. You'll need very high excursion drivers (at least 6mm of excursion) otherwise you'll be excursion limited and you'll have to use a high pass filter, otherwise you'll literally shred the woofer driver to pieces before you burn it out.
Is it just because the midrange is open back? EDIT: I saw there was a cover on there so it is probably comb filtering between the midrange driver and the midrange in the woofer with no low pass that is stepped back, causing a half wave cancellation.
6 ohm is a weird impedance value for speakers. Usually 2-way or 3-way speakers of reasonable quality would have 4 or 8 ohms impedance as standard. Those look like cheap-ass knock-offs of TEAC, Panasonic or SHARP shelf system speakers.
I have a system similar to this but it's made by Panasonic and they shake my house when cranked. The model number is: Panasonic SA-AK44. The speakers are Bi-Wiring.
Hey, What's up Garret? Do you think that you might be able to overdrive the living crap out of a big subwoofer with oobleck on it? I think it would be cool to see what oobleck does on something like that.
Ambiguous Dreams nah, the sub and midrange are producing different frequencies so there won't be phase issues. seriously... the manufacturer wouldn't be that stupid.
that's what it is the subwoofer price is getting high path it's bouncing inside the plastic and then bouncing back into the subwoofer account and bouncing back out
Was wondering if you could try too get you hand on the Sony Lbt gpx 555 and do a video on them ive owned them for about a year now and puy then through rape but they only get warm after about 3 hours at max volume they are rated at 1800 watts wondering if you could see brand new they are $500 though its definitely a powerful system though so good luck
Great video, those speakers took that power well. Do you know where that tune can be downloaded? I've found it on soundcloud, but unlike some tracks on there, the option to download is not visible.
My media PC that just streams crap on my TV is a windows PC, But I will probably fix up one of my old macbooks for the TV later but the micro PC has been doing fine other than collecting insane dust inside
