Hi guys, I've been a member here for awhile and I know that the Dayton sub has always been highly recommended for the very low budget types like myself. However, it seems as though the revamped Dayton isn't quite holding up to the older model -- this is mostly according to discussion on the AVS Forum. One sub that I haven't heard much about here is the Acoustech H-100. This was apparently designed by Dr. Hsu and gets more press over at AVS than here. I was wondering if anyone has experience with this sub. Especially if anyone has a FR graph, or if anyone could produce one for me that would be terrific. This sub is more expensive than the Dayton, but can sometimes be found for under $200 used (about $250 new). Can anyone give me info about this sub? I'd also like information about other good subs in this price range (around $250 max -- lower=better!).
