With the wide varity of high quality crossovers, and slopes available in your Theta C/B, how about a passive sub, like the Revel Sub15, and a high power, external amp.
I like the fact that the crossover, and amp are not inside the SUB encloser, and will not be effected by heat, vibrations, or magnitic fields. You would also have a hard time convincing me that that plate amp screwed to the back of most intergrated subs will match a Big Bryston, Krell KSA300, or similar type external amp.
I have a SUB15 that will be powered by my Phase Linear 700b (350 watts at 8ohm). The SUB ran me $1000 here on A/gon, and the amp cost me $412 including shipping on Ebay. Not bad for a little over $1400.
On the musical thing, if your ceiling is between 7 and 9 feet, your resonate frequency mode for that distance will be between 60hz and 80hz, and their first harmonics will be between 120hz and 160hz, sounds a little muddy in the mid and upper bass??? Yet you will blame the "SUB" for being amusical and slow sounding.
The Vandy's system seem to control the rolling off of the main speakers while at the same time controling the boosting of the Sub's signal. I'm sure many on this site can help cover this point.
Just remember there are 3 types of lies... Lies, Damn Lies, and Statistics.
