I was just curious if anyone here using SVS subs has changed out the Samson for a Crown, or some other pro amp in an attempt to change the character of the bass. I'm running one 20-39+ with Samson S1000. I have plenty of bass, but would like to tighten things up a bit. I noticed the Samsons have a fairly low damping factor of 200 -- which makes me think the driver is probably not under the best control. The Crown K-1 OTOH, has a damping factor of 3000! Seems to me this would really add to the 'slam' factor.
