I just purchased an unloaded 215 cabinet and needed suggestions for the type of 15s to equip it with. The dimensions of the cabinet are 40.5 x 22 x 15 (h x w x l). Its a smaller cabinet so hopefully Ill have some choice in what kind of sound I want to get. I would like my sound to be tight low end that will be able to handle D tuning. The head I am using is a Ampeg v4 with a MM Sterling. Im looking to spend around $250 and I am willing to wait it out (ebay) if necessary. (I have a 412 cabinet currently) I can provide more information if needed. THANKS!!
