I should start this by saying I don't really know what I'm doing so I want to make sure I'm not missing something that should be obvious.
I've been running a pair of TriTrix TLs as my main HT speakers for several years with no sub and I am really itching to finish out the HT setup. My first order of business is I need a sub(s) so I have been researching different designs. Other than having something that works reasonably well my main concern is having something that isn't too obtrusive. It occured to me that there is about .58 cubic feet in the lower chamber of the TriTrix that is unused so I did some searching and found a few people who talked about building something similar but no reports on what they used or how it worked and most were 10 years old. My plan at this point is to rebuild the TriTrix with a sealed chamber in the bottom and install a Dayton Audio UM10-22 10" Ultimax in each one. In WinISD they model with an F3 of 40hz and with a mounting depth of 5.7" they should have 3/4 clearance to the magnet. I'm not totally sure what to do about an amp, there's not enough room for a plate so I guess something like a Behringer NX1000D but I don't really care for not having auto power on/off and haven't been able to find any solutions. I'm open to suggestions, is what I'm proposing even a good idea?

Hmm, even though its vent is flared, 3/4" clearance may not be sufficient for such an inefficient, high Xmax driver in an acoustically tiny sealed alignment if/when driven to near its limits, so recommend contacting the manufacturer just in case. Would hate to have it burn up and not be covered by any warranty.
BTW, the way you've presented this 'begs' the question: did you subtract the driver's 0.022 ft^3 from the calculated space available?
Sorry, not even remotely current on anything electronic.

Thanks for the reply. As dumb as it sounds I never thought to contact the manufacturer.
I didn't subtract the driver volume, though now that you mention it I remember reading that somewhere. That leaves me with .559 and a QTC of .781
The only reason that I chose those drivers was that they required a small box, the mounting depth appeared to work and they had a fairly low F3. Your response makes me question my reasoning even more, this is entirely new territory for me and I have tried to research but I feel like I don't really have the knowledge to know if I am doing something dumb. I'm going to contact Dayton and see their thoughts. Thanks
