Randy,

Set the Denon cross-over to 40Hz, switch the 600 to 40Hz and the 350s to 60Hz and then calibrate each one to the same SPL using a 40Hz tone.

He just gets it right and now you go and screw him up. We are never going to get a review!

Is anybody else surprised we haven't blown any fuses on this project yet?

40hz crossover is to low for the other speakers, 80hz works best overall for music/HT in my opinion. Besides, I want the sub to do the work it is best at, that 80hz and below.

I know that the 150 and the QS8s get anemic below 75Hz but I've found that this is what works best. Otherwise the 600 sounds too darned "bloated" and "thick" with its 4th order, large vented enclosure. I find that I don't miss anything out of the 150 and the QS8s with a 40Hz cross-over.

BTW, this is what I liked about the 350V3. No "bloat", "thickness" and better transient response ("tightness"?).

The vent only contributes output below Fb, the subs tuning frequency. While its true all vents contribute some noise, the ports on the ep350v3, ep500 and ep600 are designed to be very quiet. They contribute far less resonance than smaller round or slotted ports found on most other subs with this alignment. Its an important aspect of overall sound quality when comparing vented subs.

Bloated thick bass is not characteristic of the ep600. In my HT, listeners usually describe the 600 as more natural and full of textures. Bloated sound from a high quality sub arises when the mains/sub are not in phase, and/or not blended well at the crossover point and/or room acoustical problems at those frequencies and corresponding room nodes.

40 hz is too low with the 150s and qs8s. If you have a flexible bass management system which allows individual crossovers for speakers I would set those at 90hz and certainly no lower than 80hz. Also setting the crossover too low puts more burdens on low powered receiver amps which are overtaxed to begin with in most HT systems.

Room treatments are always in the back of my mind but I'm still hesitant to go there. Until I do, I get far better "kick" or "punch" at a 40Hz cross-over while retaining the "soft" textures that most of us agree the 600 is wonderful at. BTW, I didn't feel these textures were missing with the 350V3; they were however a touch "harder" which I actually liked very much.

I had the pleasure of hearing the EP 600 at the other Ricks house. The last description I would use is bloated. I had a hard time believing it was even on it was so smooth.

Bloated is perhaps the wrong word. I feel the transient response is not there at the start of each note and at the end. I don't have this problem with the Sony or the 350v3. I've often thought of stuffing the box with polyfill to dampen the response but have never gotten around to it. This would sacrifice some of the low end but should "tighten" the sound (at least it did with the Sony).

Rick, was this the first time you heard a 600?

Gotta go now. Veal shanks are awaiting for my Osso Buco.

While it is possible your ep600 has issues mine doesn't, from all your descriptions and data it reads like its your room that is causing the problem combined with how you have it configured with your other speakers.
