What is your budget for a sub? Also, how large is your room? The internet-direct market has a number of very good candidates, depending on what you are looking to spend. One economical candidate would be the relatively new LFM-1 Compact from Outlaw ($400 for a 10" sub), but there are also an assortment of promising options - other Outlaw subs, HSU subs, SVS, etc.
