About 50 - 75w power handling would be more than enough. I want a clean, full range 12" speaker that has extended high frequency response and doesn't do anything other than reproduce what I put into it, i.e. no breaking up, no added warmth, no "bringing the brootalz," etc.
I have a 2-12 stereo cab with one ancient EV Force speaker in it (which I like the sound of) but the other speaker is a very ancient Sunn speaker that came with the cabinet and has much lower efficiency, very limited high freq response, and looser suspension with sloppy punch. I'm wanting to buy a tight, efficient, extended freq response speaker similar to the EV 12 and ditch the old Sunn speaker.
This is for my guitar rig which consists of a 2-12 ported cabinet driven by a MosValve head (or possibly Rocktron Velocity head) using my Roland VG-88 modeler as the input. In other words I just want the cab and amp to amplify with minimal coloration.
