Subwoofer placement is crucial. Bass frequency sound waves are big, on the order of several feet. They strongly interact with each other - if a peak hits a trough, they will cancel each other out. If a peak hits a peak, they will reinforce each other, producing overblown, boomy bass.
The bass you hear from a sub is a combination of direct sound and reflected sound. Depending on your sitting position, you could be in a zone of destructive interference (cancelled bass) for several critical frequencies. Since the wavelength is different, the zones of constructive and destructive interference move around for differerent frequencies. Here's something simple you can do - place the sub in your listening position and start listening to bassy material. Make sure no one's around because the next step is embarassing...pretend you're a sub! Move around with your ear in the same position as the driver. Investigate along walls and corners. You will find that the sound changes, you'll get boominess and cancellations as you move along. Settle on the best spot, where there's little boominess but no cancellation either - you'll have to judge. Then move the sub to that position. You can also investigate the Inguz plugin. However it's best to get placement right first, then use things like Inguz to go that extra (small) step. -- Mark Lanctot "It's like, you know, a New Age religion, but with better treble response." - Jon Heal ------------------------------------------------------------------------ Mark Lanctot's Profile: http://forums.slimdevices.com/member.php?userid=2071 View this thread: http://forums.slimdevices.com/showthread.php?t=32851 _______________________________________________ audiophiles mailing list audiophiles@lists.slimdevices.com http://lists.slimdevices.com/lists/listinfo/audiophiles
