Hi all, I manage to have two tempests sitting around. (IB setup didn't work as I planned) and an amp that'll be able to give em a nice healthy 1400 watts. (QSC RMX 1450) Well, haven't bought the amp yet, but will hopefully soon! While I'm waiting for the amp, I want to build an enclosure for them, but I'm really not sure what to build! I'm pretty definite I'll be doing a sonotube (I can't decide if I want 1 tube, or 2) Size doesn't REALLY matter, a 30" wide 5' sub would be.. fun (Of course, a 50" 8' tall sub might not be to practical.) I mainly want really 'fast and tight' bass. I'm assuming with dual tempests, and a bit of room gain, any design will have decent enough low end, that I don't need to bother tuning super duper low (12 Hz style) These will be used mainly for music (rock, punk, and a bit of classical, and on odd days, techno) However, I want them to 'work' for HT as well. Suggestions on what I should do? Should I buy the QSC? My room is about 12'x20'x8' Thanks in advance for any suggestions!
