I just went for a few weeks without my EP350, and it's nice to have it back.

So much so that you've dubbed him/her/it E3? ;\)

Hmmm... if it wasn't for bad luck I don't think I'd have any luck when it comes to this subwoofer. I got the amp in yesterday morning, I was thrilled! I removed the old amp, installed the new amp and turned on some music... awesome!!! All those statements about not needing $2200 dollars worth of bass, blah, blah, blah... out the window, I was completely happy! The more music I tested out on it, the bigger my smile got.

Then I tried a movie.

Now I'm still not sure what the problem is, so I'm trying hard not to be negative, but the performance of MY EP800 was less than spectacular. And of course spectacular was what I was expecting. It's still unclear to me what is going on, but it sounds a lot like it's bottoming out, which I thought was impossible with Axiom subwoofers? I would accept it if it were something that happened once or twice during really low frequency scenes during the movie, but it's happening constantly, throughout the movie, and it get's very annoying. I've taken the amp back out, and made sure there was nothing in the way of the cone. I taped the wires back to the support beams to make sure they weren't somehow hitting the back of the cone during it's travel. I tightened everything up as much as I could. The sound is still there during LFE scenes throughout the movie (Iron Man), and even during the testing stage of the THX setup screen. I took the grill off and watched them work. When the hz get really low and they are really moving is when they start making the noise, and it's not just one of them, it's both of them.

I spent a long time trying to diagnose the problem. I played with the setting of the Denon as well as the setting on the amp. It didn't matter if I had the level set almost to zero, it still made the sound during really low frequency scenes. I can't imagine this is how the EP800 is supposed to play, or there would not be very good reviews floating around out there about it. So once again I'm thinking that something is wrong with my unit. I don't know if somehow the bad amp it came with somehow damaged the speakers before it finally went out or what, but something is definately not right with it. I don't remember Steve's performing like this during the scene in 'Finding Nemo'... his just produced powerful bass.

Mine functions flawlessly during music playback, it's just during the low stuff while watching movies. Which is something I do a lot of, so I'm going to have to find a solution for this problem. It's such a shame. Every other speaker I ordered performs far beyond my expectations, I couldn't be happier with the rest of them. It's just the EP800 during movie time that's letting me down. But like I said, I've never heard anyone else on here complain about their EP800's, or any other subwoofer for that matter, so I'm convinced mine just has something wrong with it. What a bummer.

That blows. I am not sure what you can see when the amp is removed so maybe try removing a driver from the cabinet and inspect the speaker and the wires to see if they are secured properly or if anything else doesn't seem right.

Micah, I'm certainly not an expert but I would try rerunning the Audyssey setup. I would also try the phase switch to see it you get better sound at either 0 or 180.

My Denon doesn't have audessy, but my guess is it wouldn't have any effect really in this case. It's happening when it tries to reproduce the really low (possibly inaudible) stuff. For instance the scene in 'Iron Man' where he's demonstrating his missile system, standing on the mountian... From the time he launches the missile, throughout the entire explosion, for about 20 - 30 seconds my EP800 is bottoming out the entire time. Has anyone else here with an EP500, 600 or 800 watched that movie yet? And if so did your subwoofer rattle and crack the whole time?

I don't think there is anyway this is typical of the EP800 or any of Axiom's subwoofer line. Their speakers are way too good to sound like this. The quality of sound coming out of the M80's is a million times better than that. It can't possibly be indicitive of this speaker, it has to be an exception. Heck my Cerwin Vega handled LFE better than this.

But like I said it sounds spectacular with music. It handles everything down to around 18 hz remarkable well and accurate. It's the stuff below 18 hz that's giving it fits. And since every review I've ever read about it talks about how well it does with the low stuff, I have to assume mine is a bum unit.

Dr. House, removing the amp actually gives you a really good view of the back of the speakers. I played it with the amp removed and watched them. I didn't see any wires or anything else hitting them, but they still made the noise. Playing with the phase switch and subsonic filter had no effect what so ever.

Did you try the "20hz" filter on the subwoofer? That might help Axiom help you troubleshoot when you call them.

I've watched the movie with my EP800s and can verify that I didn't hear anything like that. I haven't heard any bottoming out whatsoever on any material.

Micah how do you know it is having trouble below 18hz, are you sending it specific signals from a test cd?

Since you say it makes the sound no matter what volume level you use, I think the drivers are also defective.

You said it handles everything up to 18hz cleanly. Have you calibrated the 800 with a SPL meter? It is possible things in the actual room could be causing rattling and cracking noises at certain frequencies and it could seem like it is coming from the sub. I doubt it but it is worth checking out.

Also call Axiom.
