raising subwoofer off floor by 20 inches

thanks guys for your comments!

i am actually quite content with my setup. the suggestion came up during a casual conversation with a velodyne dealer (i was trying to get a good deal on a second dd-12). so i figured why not ask my fellow audiogoners before i try out the placement.

Newbee, i am sending full signals from source to both main amps and subwoofer, which is set to respond to 60hz and below. the sliders are indeed equalizer adjustments made to achieve the somewhat flat response. my current goal would be to achieve similar or better results without adjusting so much of the equalizer settings.

thanks Hifidreams and Etbaby for your info. the asc subtrap is quite interesting.

i have very limited speaker placement options due to the system being in the livingroom/kids' playroom, which is 25'L x 15'W x 10'H.

raising the sub would make it look quite ugly and awkward. but you guys got me interested enough to try it. unfortunately, i don't have anything in my home that i can use to elevate the sub. so the search begins...

thanks again for everyone's input.
