Great looking HT, Mike!  Your equipment list is impressive. 

Is this a 2nd floor build?  Did you incorporate any sound isolation into the build to help contain those massive subs? 

Thank you. Existing room, not new construction and the room is on the second floor. No sound deadening treatments. With the bass that I have, it would be hard to isolate this room, with it being on the second floor.

Mike, how does a baffle wall compare to having your speakers spaced out from the wall like a traditional stereo setup? Do you get the same depth, and soundstage...is there anything special to take into consideration when building a baffle wall setup? I have thought about converting my setup to one.

Rather than type of something, I will just provide you with a link listing the advantages.

Yes, there are things you have to take into account, with a baffle wall. A lot of speakers have baffle step compensation built into the crossover. This means they could be boomy, when placed in a baffle wall. Though room correction would help that. If you are building speakers, then, just do not add baffle step compensation to the crossover.

Thanks for the link Mike. I will def read it to see if it will meet my needs better, and as you know we are building our own speakers too.

Mike, I have a question for you. Normally when people setup their room they angle the speakers, but I noticed with a baffle wall they don't...is there a reason they don't do this with a baffle wall? Would it be counterproductive to design the wall after the speakers were aimed conventionally, and make the wall conform to the speakers being angled?

Mike, that's an incredible room!  Love it.  Hope my room turns out half as nice....

A lot of times, baffle walls are angled. Some even do a curve. My baffle wall is angled for the right and left mains.

Thank you. First time I have ever gone over a year, without thinking about upgrading my speakers.

When you did your setup...did you set the speakers up best for soundstage by listening and then build the baffle wall around them, or was there some calculations you used?

[AVSMike]

Based on aiming the direct sound toward the main seat. Also from measurements and listening tests using my old speakers, that had similar dispersion characteristics, in that room.

Thanks Mike... I will be looking at either building a baffle wall for my current setup (after the new speakers are completed), or for my next HT.

People have asked about a passive crossover design for the TPL-150H and the TD12M. Here is one that was worked up for me. I believe it is crossing over at 2,200hz. See attached.

Speaker crossover parts

Tweeter Cap: http://www.parts-express.com/jantzen...citor--027-932
Tweeter Resistor: http://www.parts-express.com/mills-8...esistor--005-8

Woofer inductor: http://www.parts-express.com/erse-15...-coil--266-360
Woofer cap: http://www.parts-express.com/solen-2...citor--027-582

A couple of notes, for the tweeter resistor you have some room to play. Since you're behind a screen, you can use a slightly smaller value without throwing off phase response. For example: http://www.parts-express.com/mills-7...esistor--005-7

As for the tweeter cap, if you're into boutique stuff, you can try other brands.


Added
Note that I am using active and crossing over much lower. Have been using 1,400hz 12db/oct. Today switched over to 1,200hz 12bd/oct. Will play with that a while and see what I think. The directivity should match well between the TPL-150H and the TD12M's at 1,200hz.

Great build Mike and thank you for all the info you have shared in this thread.  Your baffle wall will serve as inspiration for my next build!

You are welcome. If I can help you with equipment, let me know.

Installed a new mounting system for my projector and A-lens. Now I can install pretty much any digital projector and easily adjust A-lens to fit.
