Aha!

I have mine set to flat but then again I have 4,000+ cubic feet. When I set it to half or full, it's too over-powering.

If one were to listen to, say, and EP400 with this feature off, and then on would that make a big difference in the 'punch' it had for music? In a 12x20x7 room which would be more likely to make your ears hurt on music?

I'd say half or full would make your ears hurt more. As for "punch" I don't know. Maybe jakeman does.

I'm wondering if that would account for the very different impression Jason and I had of the EP400.

When I auditioned, I never really paid attention to settings on the sub, I just listened to what Debbie presented me.

I don't know either Mojo...I like my punch with rum and slices of pineapple.

Fred, there is no hard or fast rule for setting trim. Too much depends on placement and unique room acoustics. Before using the trim control I would suggest leaving it flat and again tweaking placement. Generally speaking the closer to the corner in a small room the more trimming to half or full becomes viable. The concept being that the closer to the corner the more room gain will occur below 33hz. However depending on where you sit you could be situated in a peak or null so the only practical thing to do is try all the settings. Keep in mind that the trim that sounds good for HT may not work that well for music.

Thans John. I've really learned a lot from this post. Actually, you seem to have spent a lot of time to really figure this sub stuff out.

The reason for my Aha! and for posting the subsequent question is that Jason and I had very different impressions of the EP400. He felt it was smoother and less punchy/powerful than the 400. I gave up on it after listening to some music because it seemed too powerful. I could feel it pushing on my ears and interpreted this as pushing too much air or too much punch.

Nothing I had read about sealed vs ported subs or others impressions of the 350v3 vs 400 matched with what I felt.

The room I mentioned is Axiom's listening room. The HT is set up against one of the narrow end walls facing out at the longest dimension. The sus were placed up front, just off center (just inside the M60 and M80).

If I was listening to the 400 with the trim control on vs others listening with it set to off would explain my very different experience.

FWIW, my ears hurt with the 400 at its lowest volume setting, yet the 350v3 sounded just fine at about 1/2 volume.

Very interesting... (but not shtupit!)

I too felt that the 400 was smoother and less punchy/powerful than the 350v3 when auditioned in my 4,000 cubic foot+ space.

That would have been the difference. I have never played around with the trim, always left it set to flat.

Jason, definitely try the trim adjustments. This partially compensates for the room gain at very low frequencies that small rooms(contrary to popular belief)in particular add, and boosts the output above an arbitrary 33Hz to make the overall result less boomy. I was a bit surprised to see that the "Full" setting was overall the most desirable.

Enjoy the music, not the equipment.
