I have always experienced better bass from larger speakers. I know that size as well as money are concerns but if you can find a way to squeeze it in your theater you can get huge bass for very low cost. Example: Radio shack 40-1301 clearence 15" drivers got four for 120$ Two drivers push pull in a sealed 8 ft3 had clean ,loud ,articulate bass. The pair of completed subs moved the hairs on your legs. The bass of just one driver sounded thick but two helping each other canceled out all the distortion and boomy mid bass. I could not believe the detail of these cheap ass drivers! NIN downward spiral has deep layered bass transients and were very detailed. The plane crash in Fight Club actually sounded like ripping metal and 300 mile an hour winds. I recomend bracing the magnet assemblies with a sturdy wood frame because they vibrated fiercly at full volume and you will get a much improved full volume performance. These drivers were sheilded and became my new TV and front speaker stands due to there size. I had direct comparison to a pair of nht 1259s and they were beter in all aspects. Although I had to physicaly correct the drivers flaws(loud cone distortion and basket resonance) the set was about 170 dollars with boxes and was a true subwoofer, not a small sub trying to do the impossible but a large amount of air being moved by by what moves air the best, big subs. Happy hunting!
