SVT 4 Pro is $1400 new. I'd like to know on what planet that's considered a "cheaper" amp. Also, I'd like proof that Ampeg (or Kustom for that matter) measures their output levels based on 10% THD. That's ridiculously high for even all tube amps, let alone hybrids.Where you set your gain is a HUGE deal. If I recall, most "cheaper" high-power SS amps are rated at or nearly at 10% THD. (Ampeg, Kustom, etc)

are you using a 4 ohm cab? I used to play one of those through an 8 ohm 4x10 and was never satisfied with the headroom.
here's your problem. 15"s will bottom out and won't get any louder past a certain point. i imagine that point is where your hartke ends and your 4 pro takes off. also, why rear fire a cab?Sorry for the extremely late response, but yes it was a 4 ohm cab. Two 15's, one forward and one rear firing. I used this on my Reggae gig. I think with 8 ohm's you only get like 280 watts instead of 450 at 4 ohm's
With all of the Ampeg solid states except the SVT-400T, pretty much.
That's the best way to run an Ampeg pre.
