I have an Ampeg SVT-15E cabinet with a blown speaker. I'm thinking of replacing the 200W 8ohm speaker that was in it with a 4ohm speaker of at least 350W rating. So far, the only sources that I've found are Peavey (Black Max), Carvin (PS15-C4), and Eminence (Kappa-15). I would like some opinions on these speakers from anyone with experience with them. I would also like some information from anyone else who has done something like this. Good idea, bad idea? My reason for wanting to re-speaker with a heavier speaker is: 1) to save a little money and use the existing cabinet that I have; 2) I was planning on going to a heavier 15" anyway. I'm not worried about having a horn or tweeter as I usually run this cabinet with another cabinet so equipped. Thanks for all help that you can provide.
