Thanks a ton for clearing it up for me. With me being 90% movies in a mid to high end HT the CBT36's are a better choice for me. I need to just go ahead and pull the trigger...

*doh*
I totally forgot that the curved CBT36s are supposed to represent to some extent a true line source. Normal math won't work with these speakers.
While 107db @ 3m would be a decent guesstimate for a point source, a line source might be closer to 111.5db at the same distance (only half the distance loss)
I actually don't know the exact math to use for these speakers. But basically you could possibly hit 105db @ 3m with only ~100w @ 4 ohm. It ""could"" only take about 16w to do what the Phil 3s do with 300w.
Don't quote me on it though![]()

Those measurements for me are like speaking binary code to a hillbilly. I haven't researched that much yet. But I get it when you explain it. Thanks again

Hey benbodtke, I just joined up here and have been bothering people in the newb section over logistics on almost the exact setup you're working on. I'm building 4 CTB36's for my brother-in-laws Christmas present, and was having concerns on power (or, over-power).
I think I made my decision to go with an Emotiva XPA-5 to drive the Mid-Bass and Center Channels (I got a pair of JBL CBT-70J's, which will probably be on eBay soon if Audio Artistry is planning a center channel as you say). To run the tweeters, I'm planning on a pair of Emotiva Mini-X A-100's. I guess you could say that I'm afraid, with my limited knowledge of passive monitors, of overpowering the speakers...especially the tweeters.
I think the price on the Emotiva pieces is pretty decent, and I'm on the waiting list for their XMC-1 Pre as well. The crossover Mr. Keele used in his presentations was the Deqx HDP-Express (they did all their configuration on the Behringer, but with the experience I've had with their equipment in my studio I try to stay as far away from that brand as I can), so I think that will solve all my issues (you can download the preset configurations they suggest for both the Behringer and the Deqx on their website).
For Subs, I'm using 3 Genelec 1094a's, recently retired from the studio...I know for a fact they'll shake your teeth loose, but also remain true at low (volume- and frequency-wise) levels.
I'll be interested in hearing of your progress, and hope I'm not too far behind!

Your budget is far better than mine. I would love to be able to purchase that DEQX as I really dont hear too many good things about Behringer.
I believe they are still the designing stages with that center but should be pretty awesome when its done. I will probably just try and pick up a third cbt36 if I am able too, but if not will continue searching for one that can be heard.
For subs I have not decided yet, but will probably stick to what Grant has told me here. He is much more knowledgable than me and I have no problem admitting that.
Are you going to be putting them together yourself? Christmas is a long time away, or is this an overdue present. He really married into the right family.

I got a deal on a SVS PB12-Plus that I had to pull the trigger on.
