Standing vs. Seated-Big Difference in Bass???


I own some Soliloquy 6.3's. The speakers are approx 7 ft apart and sitting area approx 8-9 ft. back. When I stand the bass is perfect. When I sit (same distance)the bass seems to be reduced approx 50-60%. Can someone tell me what is going on? I can do no better than getting 18 inches from back wall, large room 20x22 with semi vaulted ceiling. I have not installed the spikes. Using AR Vs110 (100 watt tube) amp. HELP

i run sol 6.3s from an ARC VT130 in a large room w/ vaulted ceiling also. i've never been able to get clean base until @ least out from front wall 39 inches. my side walls are each more than 15 ft away, speakers 116 in apart & 9 ft from chair back. the sols have been very sensitive to front & sidewalls for me.

I have my 6.5s 72" out from the wall behind them, measured from the center of the front face of the cabinet. This corresponds to 1/3 of the front to back room dimension and gives the smoothest bass response as well as the best stereo imaging and depth. Spacing is 9' apart, measured from centers. Yeah, they're a little in the way, but they sound gooood.
