Apparently subB if far superior for loudness and quality over subA, to me they look the same??? can anyone decipher this info for me???? Also does anyone know any other brands that will be much better than these numbers,without having to go say more than 1 cubic foot sealed??

 

Well a few things I noticed is that speaker B can handle more power, which when you start turning up the volume, if your not pushing the max power rating on the sub, the speaker sounds better. (like same amp at the same volume...sub B can handle it easier) Also, Sub B has a much larger magnet, I do know that the magnet has a decent amount of importance as to the sound quality of hte sub and the power rating.

Just my 2 cents...
