It has been all too well documented that most Speaker Manufacturers seem to fail on their Subs. With Klipsch being a
possible near miss on that statement, all of the others come up short in every instance I've seen mentioned so far in other threads. (FWIW) *shrugs
(But last I checked, the 15" Klipsch was being compared to a PB2K... so a 12" was still hanging with a 15". Ummm.)
(On second thought, No speaker Manufacturer is winning on the Sub front right now.)
