I believe I have come to the conclusion to go with a 4x10 cab. What are some good 4x10 cabs out there, probably under $700? I played a SVT 410HE the other day and it sounded good, but honestly anything would sound good to what I have been playing through. How important is it , to match Ampeg with Ampeg? And, matching it with a 4 ohm cabinet would give me the most power, but would it be that much difference? Does matching it with a 8 ohm cabinet extend the life of the head, since you are using less wattage?
