is a really smooth driver, I have them in a 15" + horn box at the moment, but generally find myself using then twin kappa 12s because of the large difference in headroom. ie the twin kappa goes lots louder, being a 4 ohm box helps too!!I will probably try the Jaycar PA15s as some bass boost just to see if it works. The other option is buying some new 15" drivers, but I'm on student wages at the moment:-((
Those Eminenece Magnum HO's look rather nice in a smallish box !!
