Hmm. Sounds like it'd be much like a Riviera Bonehead (or Knucklehead, maybe? i forget...). I think the dude from Staind nailed it when he said something like "It sounded amazing on it's own... But it produced so much low end that it would clash with the bass and produce all these weird resonances with the band."
sounds like it does one thing really well- play really heavy. I'd look for something more balanced; these nu-metal guys got great results out of conventional amps, i'm sure you can do the same.
Hell, if it comes to it, grab yourself a bass cab and build a stack with a bass cab and a 4x12. THAT would be a heavy low end.
