I am in a finished basement with a w/w rug on the concrete. 26' x 19'. The front and back walls are panelling an ich or two away from concrete. The side walls are panelling with rooms on the other side.

>>Do you have anything else you can compare with - A different amp,
>>for example?

I hooked them up to my sand amp, SONY STR-DE935, the bass is a bit better. Being able to crank them up louder, I noticed that there was very 'excursion' of the woofer until very high loadness. By excursion I am referring to being able to see the cone move enough to move in and out at the ripples on the outer edge of the cones.

>>Same question on the speakers, are they bass-shy on the same amp,
>>different amps and/or in different rooms?

Not able to test this out yet, won't be able to test different rooms.

Would you like to swing by this weekend and check things out? ;)
