Axiom Home Page Forums General Discussion Technical Questions EP600 Volume Suddenly Diminished / Gone

Here's the scenario:

Sub is on, but barely audible. Even with the volume at full. It used to rock my world but suddenly no matter what it just doesn't. I was away for 2 weeks and I get home and turn on music.....no low end. I have tried multiple cables, both RCA and Balanced to no avail. Hooked up to an Outlaw 990. If I take those same cables and hook them up to my old M&K Sub it is night and day different so the cables and 990 seem to be fine. I also checked and rechecked every setting on the 990. It works just fine with the M&K. The EP600 has never been abused volume wise either. Sub has always been hooked up to good power protection on it's own dedicated circuit. Nothing was tripped when I got home. I even plugged it directly into a different circuit to check. No settings or knobs on the back have changed. It's almost like there's a mute button that has been turned on some where. My M80's are putting out more low end set to "large" or "small" with sub "Yes" or "L/R + Sub" etc etc etc. I can see the woofer on the EP600 moving, again, barely....it just has no "oomph" anymore.

Seems like an internal thing. Are there any user serviceable parts? At first I thought fuse but don't see one and would think if it did blow something that it wouldn't work at all. Also it's just been sitting idle for two weeks, not like it suddenly died in the middle of cranked music. Just turn on the music and nada, eehh, zip, just about dead.

Hopefully I'm just missing something stupid and easy but I don't think so. No one else ever touches the system besides me, and sitting for a couple of weeks shouldn't change anything. The sub is 2 years old and I travel a lot and have never had an issue before.

I am stumped. Any ideas? Thanks.

There are several fuses in the sub; that's the first place I'd look. It's also worthwhile to give Axiom a buzz.

Thanks, yeah I knew there had to be at least one fuse but I didn't want to start taking things apart and void the warranty. Figured I give here a shot first and see if any one else had dealt with this kind of issue. I'll give them a call.

have you tried unplugging it for a minute and plugging it back in? may not help, just a thought. have you verified all the other knobs on the back have not been altered, like the crossover, trim, etc.?

Before fiddling with it, call Axiom.

Yeah I've tried everything possible that I could think of to no avail. I unplugged it, put it on a different dedicated circuit, check all the knobs, cables, 990, etc etc. So many times that I start second guessing myself. And I'm not taking it apart unless told to do so.

I called them and the guy I spoke to was great,..... as confused about it as I am, but it was nice to talk to some one on a Sunday evening no less. Big thumbs up for their support. He is going to check with some one else in the morning and they will get back to me. I have no doubt that they will take care of the issue but it's frustrating not having my music work the way it should!

If you have to replace the amp and/or the driver, it's a little time-consuming but it's straight-forward. Just be careful that you don't bugger up the bolt holes, observe polarity and keep cables out of the way of the driver.

While you're in there, why don't you do what I've been dying to do for the last 6 months - loosely stuff the top and bottom with polyfill. I've often thought that will tighten the 600 up.

Your sub doesn't have fill in it?

It has a thin layer around the folded duct. That's it. Yours has more?

Mine had a bear in it.....
