I wrote a week ago about sub wiring. I've decided that I need a new sub. I have an rm6700 speaker system with a psw 303 sub. The sub is too small and weak for the size of the room. The entire room is 22' L x 26'W. The living room half is 22' x 13'. The HT system is entirely in the living room half. The receiver has low pass settings of 100, 150 and 200hz. I'm thinking of subs in the $300 to $600 range such as the SVS PB1-ISD; Velodyne CHT12; JBL E250P; Infinity PS-12; Sony SA-WX700; Polk psw505 or any other sub that you can recommend. The rm6700 speakers only go down to 95hz. Some of the subs such as the SVS and Velo have a high of 120hz. Thus I would have to set my receiver at 100hz. Considering that this is only 5hz higher than the rm6700's low will this work? (I'm assuming that the specs on the rm6700 are accurate.) What shoud I do? What sub would you guys recommend? Thanks.
