Different HT subwoofer problem--box form factor limits drivers to 10" max

[chucksva]

Okay, partly for WAF I need to accomplish all my HT subwoofing using (2) boxes which are incorporated in an existing wall unit, below the screen. Each is 29" w x 12" h x 12" deep, so about 2 cu ft net volume. Room is 14x22x8.5 ceiling, fairly live. I'm considering (2) drivers per enclosure, ie (4) total, perhaps the Dayton RS265HF (14mm Xmax) or much more economically the Dayton Quatro (8mm).
In the midst of significant upgrade to other equipment so I don't want to go hogwild on the subwoofer, but I don't want to feel like I need an upgrade anytime soon either.
Amplification is also TBD, I am toying with the idea of trying to use a Panny digital XR55 I have on hand, in which 6 of the channels can be ganged 3x100w=300w per side allocated to each enclosure.
Appreciate any suggestion, I have searched but haven't seen much comment about 10" Sub drivers, I guess for obvious reasons.

What do you mean by "ganged"? Bridging 3 channels would be a very uncommon feature, are you sure you can do this?

Here are a couple suggestions for subs: Fi Q10 Ascendant Assassin or Arsenal

I don't know much about the all the different subs. What I can say is the Dayton will probably have lower distortion and a slightly bigger box. The Fi Q10 or Ascendant Arsenal will have a smaller box, and greater excursion/higher SPL.

BTW if any of the sub gurus here could comment on the Ascendant subs versus teh Fi Q, TC2K, SS Rlp class drivers I would appreciate it.

Yes, Panasonic calls this "dual amping" for 2-channel playback. This receiver can also "bi-amp" or "bi-wire" for 2-channel playback, where separate amplifier channels are allocated to the HF and LF of speakers whose terminals support this.

Re-reading the manual shows me that the "dual amping" feature only gangs 2 amplifier channels per side. So, if I was using (4) drivers total anyway, it would be just as easy to drive each with a separate channel...

I don't know if the power supply in the receiver will be able to deliver 600watts continiously like a regular amp would....it might be okay for the RS265. IMO the Quatro isn't worth consideration.

If you go with any of the more manly 10's say the Fi or SoundSplinter, you'd certainly be better off using something like a Behringer prosound amp
