Hello, I'm considering getting a Mesa Powerhouse 4x10 or an Avatar 4x10 loaded with Kappa Pros. It's been difficult finding the technical information for the Mesa 10" speakers (even from Mesa directly...very unhelpful, you'd think they'd want to sell you something, wouldn't you?) Anyway, what I would like to know for the Mesa Powerhouse 10's are: 1. Voice-Coil Diameter length in inches, 2. Magnet Size, 3. Frequency handling (low to high), 4. Sensitivity dbl rating, and 5. If possible, x-max. If anyone has the same info for the Mesa Powerhouse 1x15, that would be great too. Would anyone who owns a mesa 4x10 powerhouse cab mind taking yours apart and telling what information you can find on the speakers? Also, would anyone else who knows the specs or knows of anyone more helpful at Mesa that I can call could you please provide the specs or the contact info for someone at Mesa? Thanks in advance for responding.
