Ive done the 2x10, 4x10,8x10 thing and still do but, I am reconditioning an old earth 2x15 cab from the 70's. This was my first cab that dear old dad bought me many years ago. It had two 15" SRO's (used) which I had re-coned a few times. Now that the voice coils are blown I need to find some awsome new speakers that growl. Anyone have any suggestions? I would prefer 300 watts rms min per speaker. The cab will be driven by an SVTII, Eden 300T, or SWR 350.
