Andrew was kind enough to come over again and aside from talking me into another amp and 4 more subs he adjusted everything and had Audyssey do it's thing. Sounds really good and is a huge improvement from what I had before. No fault of my components, speakers or subs but I really want to feel like I am at a concert when I watch concert DVD's. Looks like 4 more subs will be ordered soon. Due to space I will be going with 4 of the SS-18.1 passive subs. Looks like 4 more subs, another Crest CC4000 and probably move up to a Denon 4311 so I can adjust the audio settings on the fly.

This is still Latin to me but here is a snapshot of my subs thanks to Andrew. Looks like flat to about 14hz? After the additional subs I will toy with the idea of adding an EQ. That will also give me some time to figure out what an EQ will do for me!

Adding the additional subs will give you the headroom to stay flat up at louder levels. I would set the center frequency to 29hz with a cut of 6-10 dBs and play around with the Q. The lower the Q the greater the range. So a Q of .1 would cover a very large range. Someone who knows this better can tell you exactly what to use. I just tweak and measure, tweak again and measure. I keep doing that until I get it the flattest because it takes seconds.

So while it will be a better location for the other seating, it will be off-axis for me (and I am usually watching by myself anyway). Its placement now - a little "off-center" 'to the right - puts the speaker directly in-line with my ears.

Alternative: Relocate equipment rack to other part of the room and hang center channel just underneath the TV.

Wherever you put the center speaker is where sound will appear to come from. From your pictures it appears that your main listening position is only about 2ft to the right of center. Your off access angle should be well within the design radiation pattern of the compression horn and waveguide. Just for fun, move the center speaker to a centered position under the TV...Listen... then move it to your current position...Listen... I bet you a Slurpee that it sounds noticeably better centered directly under the TV. You are also getting more reflection from the floor in your current location, that tends to negatively effect the sound quality. Just do some experimenting and let us know what you find out.

The way it sits right now (cabinet off-center to the right), the tweeter is pretty much centered under the TV; if I center the cabinet itself, then the tweeter will either be off-center to the left or right (depending on which way I lay the speaker on its side)...

Everything you're doing can easily be changed back. You're displaying symptoms of paralysis by analysis.

You might consider a wall-mount for the TV and standing the CC vertically to match the L&R.

I have already stated that wall-mounting is not possible because there is a window behind that curtain.

And as far as my question about what should be centered, I am just curious. Yes, I understand that whatever position sounds right to me is where it should be...but I would like to know the "rule-of-thum" (if you will) just...well just because I would like to know.

Having the speaker off center, to the right, is likely the reason why "everything sounds like it is coming from the right of the room."

IMHO, you should center the cabinet. It is the collective sound of both tweeter AND woofer which defines where the sound is coming from.

The tweeter waveguide has a 90 degree horizontal dispersion pattern. If you center the cabinet, and you are sitting within that dispersion quadrant, even though you may be sitting off center, you should be getting virtually as much from the tweeter as if you were sitting directly in front of it.

Judging by the photo, you have the center channel too low which is why everything from the center sounds detached from the picture (low). If you could get the center closer to the screen, that problem would be solved.

If it were me, I'd switch the receiver and the center channel speaker, center the speaker, and put the knick knacks on either side of it as you originally had things. As for the speaker blocking The TVs IR sensor, that easiliy can be solved by using an inexpensive IR repeater like this one from Monoprice.com.

I may have mentioned that before, and if not here then I definitely did on the thread I posted a link to.
