I'm looking for some loud bass (not competition winning, but I do like it loud) but I also want tight, accurate, good sounding bass. I'm looking at the Q series and I'm wondering what you think of the choice. Would a 15" speaker be overkill? Also the recommendation is 2-2.6cuft, as long as it's within those measurements, will it make a difference if it's 2cuft, 2.3cuft or 2.6? Would 2.6 be loudest? Also, I'm thinking of make a fiberglass enclosure and having the sub face inside the enclosure. thanks also another quick little thing, around how much do these subs weigh?
