Randy, there're a couple reasons for not being so concerned about precise placement that you'd consider suspending one of your subs: first, an examination of the both the null and cancellation diagrams in the article shows that they don't suddenly go from one extreme to the other, but instead follow gradual curves. So, if placement was a little bit away from the point of max null or max cancellation there would still be benefit. Second, your room isn't completely rectangular and the modes in an irregular room have a somewhat different distribution and are a lot more difficult to calculate, as some online sources show. It could be reasoned that placing your back sub farther to the right, more nearly in the middle of the back wall rather than directly opposite the front sub, would more closely coincide with a null in the rear area.

Thanks everyone for the help, it is much appreciated. Since my HT area is in the top/left corner of the overall room, I've been trying to imagine how that compares to a rectangular or square room.

Also, between the bar and the wall is a large entryway/hallway (8ft wide) that leads to the otherside of the basement which includes the stairway, bedroom, bathroom, and storage rooms. Overall Sq Ft is 2100sq ft.

The 6 ft bump out wall which makes up my AV closet was actually built by me to help set back the projection screen from the rest of the room. In reality, the room was like 31ft x 30ft before I added that bump out area. I'm sure I will have to experiment to find the best position.

I just need to figure out what I'm going to do.... \:\)

I remember the M80s hanging from the ceiling.

I don't know what subwoofer you're talking about being built-in, but you made me think of the Thigpen Rotary Woofer, which "must be professionally installed in an attic or basement which becomes an infinite baffle." Does anyone on the board actually have experience with those?

Pictures would be a requirement--not of the finished product, but the journey there.

And some from the ER visits as well....just in the interest of keeping the photo essay complete!

Typical cost after installing one of these is between $20,000 and $25,000 !

Are you excited because that's pocket change or your retirement?

Thanks to my good friend Rick (Wid) for finding the pictures for me, here is the room with the hanging 80s and the *infinite baffle* sub I was referring to ... Rick also had to tell me the subs name because I forgot.

Here's the photos...

Hanging 80s, Infinite Baffle Sub ... Anybody remember his screen name?
