I can fully appreciate the need for a relatively high end soundbar market but this is just too crazy.

Highlights for me are the "full range" 2.25" drivers and that they're describing two 10" woofers with 600 watts RMS (total) behind them as "hell-shattering."

Not sure if this is the best thread for this but it's my best guess so I'm going with it. Also it's probably gonna be long and there will be NO TLDR. You have been warned.

Saturday night my sorority house neighbors had a big party and I took that as an excuse to use my HT at never before heard obnoxiously high volumes (since presumably if there are any complaints they will be the recipients rather than myself. Also to show them that my stereo (and by extension, myself) is better). Literally max on the receiver and IIRC 3 dB higher on the subwoofers than Audyssey set them at.

And that's when I smelled the smell. Or after an hour or two or something.

At first I thought maybe it was my new subwoofers getting really warm for the first time. Like I couldn't tell for sure if it was the "you let the magic smoke out" smell or if it was the "this thing has never been hot before" smell like you get with new motors and some new electronics and stuff. And I'm still not 100% sure (but pretty sure it's the bad one). But maybe I can't really tell the difference between those smells, and I'm just kidding myself.

Anyway I'm 97% sure that I've isolated the smell not to the new subwoofers but to my ~15 year old speakers. But it doesn't appear to be what I would have guessed, which is one of the amps on the speakers going out (don't ever buy partially self powered HT speakers, kids). It's definitely not the amps powering the 12" in the towers, those are working fine. And I don't think it's the amp that powers the woofers on the center channel because it seems to be working normally and I couldn't detect the smell coming from the center despite rubbing my nose up all over it. Smell seems to be just coming from the towers.

So did I fry some components in my crossovers? All the drivers appear to be outputting sound (kinda hard to say for sure with the tweeters even shoving my ear up to them just because of the sound from the other nearby drivers, but maybe if it's kinda hard to tell that means that's where the problem is). But I can also still smell the smell. I could smell it when they weren't even on by putting my nose up to the seams in the speakers, but now after running them for an hour I can smell it just walking by them.

And there definitely seems to be a sound issue. I'm afraid of confirmation bias but they seem kinda flat and atonal. Maybe especially with dialogue? But then I set the receiver to No Center and it still sounded bad. So either theres ALSO is a problem with the center or the LRs were loving things up enough that the center wasn't overcoming it. It's not bad enough that I can definitely say "this poo poo is broke" but I'm pretty close to saying it. Need to test with a few more sources maybe. But pretty sure.

So anyway, is that a thing? Cranking it enough that you fry your crossovers enough they smell bad and are roont? I assume it is but I've cranked a lot of system over a lot of years and never done it before. But these are fairly elderly and complex (4 way, partially self powered) speakers.

Any recommendations on testing? I've already eliminated the center as the culprit (or at least the only culprit). I've also turned off Audyssey and monkeyed with various other receiver settings. I can pull them apart to disconnect drivers one by one to narrow it to driver issues? That's what I did when I had a problem with the same center channel, one of the woofers was bad (or was it the mid? I can't remember).

I do have a spare tweeter and (I think) spare mid. No spare woofers. But I don't think it's a driver issue. If it is, it's a tweeter. But I don't think so. It's not like it stunk up the whole room but it got pretty smelly and I wouldn't think there'd by anything in a little 1" tweeter that could do that.

Their (Harman Audio/Infinity) used to have parts for sale on their website (even years after they'd been discontinued) but I can't find them now. But tbh if they're messed up I don't think I'll fix them I'll just sell them for parts. IIRC the crossovers were 200 bucks+ back when you could get them factory direct so I don't want to think about what someone would charge for one if they're hard to find.

Which brings us to the fun part of the post (thanks for sticking with me!), what should I replace them with assuming they need to be replaced? I need to think about it a bit more in terms of budget and what I'm looking for but will post that after some more thought.

The easiest troubleshooting steps would be to unplug everything except a single speaker, play some music, see if the sound is distorted, and if the smells comes back. If it doesn't, unplug and try the next one.

Also, get a fire extinguisher.

The smell definitely comes back. On both speakers. That I'm pretty sure of. Like even when they're off I can still smell it a bit if I put my nose right up to one of the seams in the speaker, but playing them at moderate volumes for a while seems to make the smell worse.

TheMadMilkman posted:

Smells like burning and the sound has changed?

Sounds like you may have warped a voice coil in one of the speakers. You could have damaged the crossover somehow, but the voice coils are the most likely culprit, because they're the part that physically moves. High current (max volume) plus possible clipping (max volume) plus high movement (max volume) plus a lot of time isn't the best idea, so to speak.

Hook your phone or computer up to your receiver and unhook all but one speaker. Use an online tone generator to slowly run a frequency sweep. That will let you isolate the different drivers and try to figure out which one might be damaged.

Yeah googling "voice coil" and "smell" results in a lot of people saying exactly what you're saying.

lol whoops.

Probably doesn't help that I also found this about my particular drivers, but maybe it's not relevant:

quote:

I Had a pair preludes a few years ago that i sold only because the mids are known to be faulty and are no longer available from infinity, the coating used on the neo magnet peels off and scrapes the voice coil, found this out when i took apart my old mid, Harman denies any such problems yet many people have complained of the same mid problems

Ebay has a couple used tweeters but no mids or woofers.

I think I'll try and isolate which drivers are causing the problem(s) and then sell everything else for parts. It's probably time for a change anyway and there were aspects about these speakers that I never liked a lot.

I didn't have a great subwoofer is part of why I bought these towers. Now I do have great subwoofers so I think I'll probably go back to a higher end bookshelf?

bird with big dick
Oct 21, 2015

I was thinking back to a bookshelf but after listening to some in person I'm leaning back the other way.

One of my main criticisms of the Infinitys was that they're basically just a (3 way) sealed bookshelf bolted to a sealed 12". The sub is (non-adjustably) crossed over at 80 Hz and the "bookshelf" has a single 6.5" woofer. But now with much better subwooferication, I worry about the ability of something like the B&W 705 with only a single 6.5" to really be able to keep up in the 80-200 Hz or so region. With something like the 702 you've got advantages of: 3 way vs 2 way, 3x6.5" vs 1x6.5", +2 dB sensitivity, and 2.5x the power handling capability.

I should probably get something like JTRs so I could go apeshit on them and it wouldn't matter when I'm drunk af and crank the amp to 11. But their pro audio looks and size are kind of a turn off and I'm not sure I'd like them for music. Just because of my room layout/limitations narrower speakers are also better so an <8" wide tower is definitely preferable to a 12"+ wide tower.

Went with the B&W 702s and the bigger of the two centers and I'm in heaven so far. Still need to fart around with placement and run Audyssey. They're rear ported so I should probably try pulling them out a bit more from the wall and experiment with some toe in.

Also thinking I might get some B&W DS3s (dipole/monopoles) and upgrade from 5.1 to 7.1. My last house the room wasn't big enough for 7.1 but this one it should work nicely.

Does anyone else remember (or has it already been posted in this thread) the guy on AVS that was taking ERS paper and wrapping it around toilet paper tubes and then running his cables through it? And then IIRC started opening his amp and receiver up and just wrapping ERS paper around everything possible? I saw this thread and it reminded me of that and I hadn't thought about it in 10 years. I'm pretty sure it was a performance art piece rather than a true believer or someone that was just mentally ill but the dude went to some pretty amazing lengths in taking photos for his posts so actually maybe it was both performance art and mental illness. Some googling turned up the thread that I think I'm recalling, but all the images are gone.

Baking with ERS Paper

Since I removed all the ERS Paper I had a lot of small pieces of ERS Paper, I didn't know what to do with them, so I made a Valhalla with toilet paper rolls in 3 layers. The live and neutral signals are inside their own tubes, Tara Labs style.

I didn't think it would take so long to make, minutes turned into hours, hours turned into days. After 12 hours I already started hallucinating, it felt like someone was in my room looking at me. I didn't want to spend the time drinking water because I wanted to finish the cable. I didn't want any toilet breaks either. After a while my vision started getting blurry but since I'm no quitter, I just kept on going to the end. At one point it felt like I was baking rollcake.

It was the first and probably the last time I ever make a cable with 3 layers of ERS. The ERS Paper around my 1m Valhalla power cord costs almost a grand.

I used a dozen toilet paper rolls, cotton thread, packing tape, packing foam, dozens of sheets of ERS Paper.
All the layers of ERS Paper are separated with 1cm, because less than 1cm makes it sound muddy.


Listening

I have a 1m Valhalla plugged into the wall that has a single layer of ERS with 2-3 layers around the connectors. I switched to my newly baked triple layer Valhalla with nude connectors. It sounded a little smoother but the difference was very small. I switched back and forth and eventually didn't hear a difference.

Then it was time to compare a nude Valhalla vs my triple layer one. I had nude conductors hardwired into the Toroidal transformer of my DAC1 and the other end was plugged into Premier Power Plant. I replaced it with the triple layer Valhalla and the difference was HUGE. The whole openness flavor had shifted into blackness with more low-level detail, it is scary with new sounds all over the place. Based on previous experiments, the improvements with ERS Paper are cumulative. The more you wrap, the bigger the improvements. After the full system is wrapped and you have a tiny gap somewhere, it is audible.

Next I'm going to wrap my amp.

Cat5 and cat 5e don't make a great speaker cables.
The gauge is too thin to be used over long distances. Also they're fairly high capacitance and that could gently caress up your amp or at the very least, cause high frequency loss. (not likely to be noticeable unless you have supersonic hearing.)
If you try to remedy this by twisting all the white pairs together and the solid color pairs together, then you've got a problem because the number of twists per inch varies between each pair. This is done to reduce crosstalk between the pairs, but the result is that each pair will have a different impedance.

Besides, after all that work you would only wind up with an 18 gauge wire anyway, which means you still can't use it for a very long run. For optimum performance 10 feet would be the max on an 8ohm load, half that for a 4ohm speaker.

This was a thing like 15 years ago or something. You braid enough cables that you end up with 10 gauge or so. I made a pair at the time because it gave me something to do during an Alaskan winter while I was sitting in front of the TV and I wanted to prove that they were nonsense, but I never used them long term because they’re so stiff and bulky. I probably still have them in a drawer somewhere.

Non curved line arrays exist also, of course.

Nice. I looked at those for winter wheels but then decided to use the factories for winter and get new wider summers but I don’t think Rotiform makes the rights size/offset for that.

Ford switched from Sony to B&O for their “high end” systems and I’m pretty sure they just changed the sticker on the speaker grill. The system isn’t terrible in my Mach-e though. I need to see if I can fit a little sub under the false floor in the trunk.
