Just needed a drop of deep bass. I generally do not even know they are there unless I am playing loud. They kick in at 46 Hz and -20dB. No bloat that I can hear unless I think about it...do you really need to pay 3X for more bass control?
By the way, I first tried one sub and then bought a second one. My ears tell me that, with my gear and in my room, two subs are better than one.
