Hartke cabs for me, have always worked well with Ampeg amps. Its a strange one as I have tried lots of cabs with an SVT3-Pro, it hated the Ampeg b115 and 410HE cabs but loved the Ashdown Mag 8x10. I currently own an Ampeg PF50T it sounds fab on my Hartke AK410 and HyDrive 112. I did though, have the opportunity to try it wth both and is what I would advise if thinking about change.
Good luck, Andy
