I think that is a little hard to say. Different speakers sound different to different people. I have a 4x12 cab loaded with 500 watt Pyle Drivers. I think it sounds awesome playing metal. But a friend of mine prefers Celestions for the same type music. Although I think both sounds good, he hates the way mine sound. I think you need to get out there and play through some different amps/cabs. and see what you think.
Its the same with home stereo speakers. If you have only heard the little Bose satellites you will think they sound awesome. Until you go out and listen to say....some Definitive Technologies BP3000's. Then you will see the difference.
just my .02 worth......
