I think i should have tuned the box a little higher, or it needs bracing. Probably both. Although i did do a 1 inch void free birch front plate. It's 4 cubes at 29hz. It kinda gets sloppy on double bass not bad but i notice it. Hell it could be car panel vibrations making it sound sloppy.
I'm gonna build a new box once it gets a little above freezing outside:uhoh:
But yea, that sub wangs. Gonna see if i can get it metered, i found a guy with a tl thats within 20 min of me.
For the o.p. the q is better if you want to get loud on less power and get more sq. The bl is a little less sq and a little more spl, increasingly so with the options which can increase the power handling quite a bit. The bl's have potential to get louder than q's, but probably won't be much.

i was gonna put my 18" in 4 cubes sealed tuned to 32...maybe not now
