I nearly pissed myself...
Sheep you rock buddy...
Ultimately, I think gaging the price bracket that Fired up is venturing into, he is looking to invest a substantial amount of $$ into a sound system here... and the utmost in SQ is evidently important IMO from what he has alluded to... In that case there are only a few positions one can take at that point, that can be had in a small footprint....
Paradigm Servo-15, Velodyne DD15 - both of which are still getting close to large, and are also starting to show their age in todays market.
JL Audio F112, F113 or the Ultra13, the Ultra13 of which is completely out of the question in the Size department or I would have bought one as well....
Or
A DIY sub, which would have infinite possibilities, and can be the utmost in SQ depending on dedication, but are definitely not the plug and play type of sub scenario.
Personally I am a bit biased right now with my recent acquisition of a F112, an incredible sub, a bit expensive, but is pretty much the best of the best in the commercial offerings... If your talking about a small form factor.
