a good say to check on this fast or slow subs (response) is to shut down the amps and leave only the sub on while music is playing.
i find it's not very "musical".
when i hear very low freq. sounds that seem to be directional, this is caused, i suspect, by harmonics of the instrument playing those sounds, higher than 80 Hz.

I was thinking about the area of the driver in the SVS Ultra 13 vs the 4 Axiom 6.5 inch bass drivers. The area of the SVS driver is pi/4 * 13^2 = 132.7 (approximately). The area of the 4 Axiom drivers is 4*(pi/4)*6.5^2 = 132.7 (approximately) (I thought is was kind of a funny coincidence when the numbers came out exactly the same).

Cool! I'm to lazy to figure things like that out. I does show why the M80 has such good bass. Though there is more to a good driver than radiating area, it sure is a good start.

Yeah, Jacques; I've suggested a few times in the past that disconnecting the speakers while leaving all settings the same(e.g., with a crossover to the sub of 80Hz or lower)and then listening to bass-heavy music on the sub alone will cure any illusions that subs are "musical", "fast", "tight", etc. Any such qualities of bass instruments(and also being able to localize them)are due to upper harmonics played by the speakers, not the sub.

Enjoy the music, not the equipment.
