I've been reading the forums a little bit to get a feel for the subs and read some reviews. I'm havin' trouble deciding on the BL or the Q. I've been hearin' that the BL is the poor man's BTL but also I've been hearin' that the Q has the ability to get louder then the BL? I'm lookin' for just a daily 15" that will be powered by a Clarion DPX11500 1500 @ 1 ohm. I'm leaning more towards SPL a little bit more then SQ. Any advice or suggestions? It would help a million. thanks
