As much as I like the sound quality of the M10W5's, I think people in our boat are there for the party (loud music) and could careless about SQ. I just hope that if I buy and install a set of high output (SPL) type subs that I don't dislike the sound they produce. I am willing to give up some SQ for volume.
Going back a few years I replaced a JL sub with an Alpine Type R. Hated the sound of the Type R, didnt seem to be faithfully reproducing the music, so I removed them. that was in a vehicle tho.
