thats not necessarily true. my btl has an FS of almost 37hz. in 4.5 cubes @ 33hz, it plays as low as my buddies 15" xxx in 4 cubes @ 29 hz, and gets much louder down there as well.-lowest Fs(I hate the sound of a sub with a 32hz fs... you have to tune too high..) -most useable for my application
-long useable throw
-good reliability
-must NOT fatigue over time
as for what i look for...good price, reliability, proven performance history. things like that.
