If you look at the V2 EP175 it has the dual holes, pretty safe to predict the V2 350 had the same. The slot port is from the fact the V3 uses the EP500 case now.

Hokey dokey.

One of these days I want to try that calirating stuff, sounds like it *could* be fun.

Congrats on the deliveries Randy, can't wait to hear about your thoughts on this awesome combination!

Hutzal, to get my 600 at 75dB' on the meter, the gain in the sub as to be at a min. with the receiver on about -6dB. There is no way I could use +10, unless you want me to blow out all my windows, that would be like 100+dB's or more.

Tom, Yes, I have tried nearfield, next to the seating area, and currently I moved it to the back wall next to the walkout doors, this is crazy.

Well, as long as you have a camera present, I think blowing out your windows would be quite fun! That is so strange about Denon's. On my Yamaha, I am able to set the DB level of the whole system (the main volume) prior to calibration. It isn't a set volume, I didn't really see how it would be a problem, but now I can see in your case Randy, that the Denon's calibration set volume can be a bad thing.

Yep, the old 350 had dual front circle ports. Rick, I know you don't have a Denon, but your room is smaller than mine. Where do you have your receiver gain and sub gain at? When I had my 600 in the front left corner, I was able to get it up to about 7 o'clock but no further and still had the Denon at about -4dB.

This has to be a Denon thing.

Randy without looking at the receiver's sub setting, I'm thinking the receiver is set to -7 for the 600 and the sub's level is a little less than a 1/4 turn from off.

It doesn't take much volume for our room.

That is what I'm experiencing, my 600 is all the way off, and I have to put my receiver at like -6to7dB's to bet it showing 75dB or so on the meter. The problem is that I have to really crank up the gain on the 350's because the receiver is so low.

Then when I turn them all on, my SPL goes through the roof. I would think you would want 75dB's with them all running, which will be impossible with the 600 the way it is.

So what you're saying is you have too much sub.

Randy you need to get John's (Jakeman) phone number!
