So did you calibrate it correctly as we asked above. Where do you have the gain setting on the sub and receiver? It should be matched to the other speakers using the built in mic, if you have one, or an SPL meter.

FYI, the iphone app store has an SPL meter that is fairly accurate. It is the ultimate ears app.

I doubt i'm over-driving it, though I'm no expert. I'm using it with M3 bookshelves and a vintage Marantz 2235b (35watt RMS).

I'll turn the receiver volume up less than 1/2 way (usually about 1/3), turn up the EP400 volume less than 1/2 way (usually about 2/5), and then play a bass heavy song (like dub music or hip hop) and when the subwoofer is really going in and out strongly, the rattling sound will start.

I've tried using both RCA and speaker-line to the subwoofer, and experience the same rattle at these volumes.

I've spoken to Brent and will give the EP400 a bit of an inspection. We'll see how that goes...

Are you sure its the sub?

I have an Outlaw sub and only have the volume on its amp turned to 1.75, yet when I turn up the volume with Bass heavy tracks I also get an annoying rattling noise...

I found taking the metal framed pictures off the wall resolved the Subwoofers issue wink

snazzed

For clarity: The picture frames were vibrating against the wall.

Sounds like something isn't right. Definitely contact axiom. For the $$$ you spent on an ep400 you should be more than satisfied with it's performance in a bedroom.

Edit: feel free to follow with comments about bedroom performance wink

I'm betting you are over driving the sub, it isn't meant to pound with heavy bass just fill in the lower end, not that there still couldn't be something loose but I would guess what ever is rattling was brought about by being over driven inspite of the DSP. Perhaps the DSP program is a little too lenient allowing too much movement.

Just thought I should let Brent know - I wasn't able to do the suggested inspection of the EP400 last night. Instead, took the gf out to see The Tea Party immediately after work, and then crashed at her place. Aw well...

Oooohhh, Charles gives a tongue lashing.




Likely with a mechanical cow tongue.
