[QUOTE="Robert_E, post: 39969, member: 853"] I played around with house curves (As explained by Mr Wayne Pflughaupt at HTS) and settled on a 6dB slope rising from 90Hz to 30Hz then leveling off. (Actually it was his example) After calibrating flat then applying this house curve the sound has really come alive. I found that peaks in the sub response above the crossover point was muddying (don't know if that's the right word) the sound. (I only noticed this doing a A-B comparison with the bypass button on the BFD). I've also changed the crossover frequency from 80 to 70hz (on the pc) and from 80 to 60hz on the AVR (The AVR only supports 20Hz increments) because of the null at the sub's frequency response at 80Hz. You can hear the improvement this makes in real time while switching the crossover on the X-fi soundcard during music playback. To celebrate my new plasma screen I had a couple of friends over and we watched transformers. I was expecting some fluttering sound (happened when I pushed the gain up ridiculously high on the SVS during deep bass scenes - ie Titan AE's ice crystal scenes) because of the 6dB higher level from 30Hz downwards. Boy were we all surprised when the whole apartment was shaking during that rocket-jump-over-the-lady deep bass sweep! ;D The baby SVS still impresses me more every time I use it! Up to now I was just playing with EQ for the fun of it, but after last night I am a true believer! ;) [/QUOTE]
