I’m not sure if this belongs here or in speakers or in tweaks… Mods, please feel free to move as needed. I'm giving serious thought to adding an ICBM to my system. I'm in the early stages of acquiring DVD-A's and loving the sound with a few minor exceptions. I currently have: Pioneer Elite VSX-39TX, JBL S38's (mains), JBL S-Center, JBL HTI8 (in wall surrounds), JBL S120PII sub, and a Panasonic RP91. The speakers reside in a largish entertainment center along with all of the other electronics. Don't bother to try to get me to take them out of the cabinet or acquire something other than in-wall surrounds. The decorator has spoken... I lost... end of story... There in lies the problem.... In spite of multiple layers of isolation (VibraPods) under the main & center speakers and all of the "mechanical" devices in the cabinet I'm still having issues with deep bass at high volumes (85+ db). The only answer so far has been to set the speakers to "small" in the receiver (the DVD is set to large) and let it try to re-route the bass to the sub. Let's just say that I'm not happy with the results. The available crossover frequencies are 80, 100 & 150 Hz. The receiver doesn’t appear to allow for setting different crossover frequencies to different speakers. I really believe that the mains could stand to be set to 60 Hz (or so) so long as I could set the center (seems to be my problem child) to 100 (or higher) and not be trying to pump so much bass to the surrounds (they just can't handle it). So... Tell me... Does it sound like I'm a good candidate for an ICBM? Of course any and all feedback is appreciated. THANX!
