waiting for these^^^
I recently upgraded to an HP amp, IMO it kind of refines an already fantastic subwoofer........that is about all I can say.
The next time I do an AVR upgrade I look forward to XT32 (and whatever else is available in a yr or 2).
But no upgrade to the SubM/HP will be necessary!
Same here millerwill - my HP is revealing nuances and sheer grunt that I've never experienced before.
Quoting Craig from earlier who said it better than I could: "every rumble tone is different, with a different frequency signature; a distinguishable sound and tonal structure. I have heard some massive ported bass systems with huge output capabilities, and none have the tonal structure that the Submersive HP's..."
YES! So cool...
