Hmmm i don't think you'll need an icbm, your preamp seems to have the right features. That whack in the chest feeling you are looking for occurs in the 70-80hz area. Real bass below 30 is felt in the bones more then it is heard. I'll bet your friend was using a subwoofer that didn't have as flat a responce as your subs. My first speakers were a pair of cervin vega at-12's. They could hit you in the chest like oj but really didn't put out much below 40hz. If you want a flat responce you can't have a big bump in that upper bass region. I now how have a pair of Dynaudio 1.8's which have a much better bass responce, but don't put out nearly as much slam as those old vega's. It could be that your gear is too good. You probably have a nice flat responce down to the upper teens, i bet with the right song you could crap your pants heehe. What you need to do is un-audiophile your gear a bit. Set your speakers to small, and your crossover to 80 or 90 so your subs will work that upper bass. Set the subs to max output and let it rip. Make sure there are no pets or small children nearby and then play some good old rap music or that scene fom Heat where they bust out of the bank. Those M16's should sound like a sledge. In responce to your other question, the .1 is a discrete low frequency channel movie makers use to place only low frequency information. The information on this track will only be sent to the subwoofer if one is present or 'large' in a system without a sub. When speakers are set to 'small' all information below the crossover point is redirected first to the sub, and then to any 'large' speakers. The bass management abilities of preamps and recievers varies greatly and tends to be the weakest link, but if you can choose the crossover point, you probably have a pretty good one. Having large speakers in a hometheater setup is still a good idea because all channels are full range these days (20hz-20k).
Subwoofer slam vs boom
Generally speaking what causes a subwoofer to be boomy, verses crisp and "slammy"?
Does placement and room acoustics greatly affect this, or is this just a common problem with lower end subs?
Currently I am using 2 HSU VTF-3's with opposite front corner placement, with all speakers set to large. The processor supports stereo subs, kinda a moot point with all large speakers thou. The subs should be doing the least amount of work possible, i.e. I am not rolling over 7 channels into one sub.
Thanks all
