I'm getting ready to purchase a new Ampeg rig and was looking for solid advice about what is the best way to go on this. I'm looking at an svt pro 7 head and wondering about cabinets. I was thinking about using a 4x10 and a 1x15. This starts to get into questions about Oms and watts. I looking at Ampeg cabinets and really want great low end. As I believe the 1x15 will be a weak link, would it be better to get two 4x10 cabinets as reviews are saying that they get really great low end. Also, ported cabinet or fully enclosed as far as bottom end. Thanks for the help!
