I just put 8 Faital Pro 10FE200 in my Hartke XL cab so I thought I would share the outcome. I'm powering it with a Ampeg svt 4 pro in mono bridged at 4 ohms. I didn't like the lack of warmth and the chunky/awkward sound. I wanted to match the power handling of the cab to the head so the Faital Pros were perfect at 150 watts rms and 300 peak and they were affordable at 44 dollars a piece. I owned a 8x10 Ampeg svt classic at one point and thought it was total crap, made out of particle board and 160lbs of mud. I'm sure the heritage sounds much better but those are pricey. The Hartke is made out of decent plywood and built fairly well. The first time I plugged it in I was blown away by how much louder it was then with the aluminum drivers, it really felt like it had some balls. The tone was everything I was hoping for warm full bodied sparkly and gut pounding bass all at the same time and it weighs about 30-40 pounds lighter now. Needless to say I was really happy it sounded so good.
