That's pretty much what the amp tech said to me yesterday. I originally wanted to get an Xti4002 for my IB because of the built-in DSP, but once I told him "what the hell kind of subwoofer" I have so that I was interested in anything below 20Hz, he recommended I go with something else, because the Crown has a built-in subsonic filter and the only way around it is to set the PEQ at 20Hz with a small Q and boost it to the max (12dB? 15dB?), but even then the Xti might not have much power down that low.
He recommended the t.amp proline 3000 (3kW). From a technological POV that thing is a bit outdated and heavy as hell (almost 90lbs), but simply amplifies what you feed it. If 1 Hz kills your speaker, it's your problem
I didn't really crank it up yet, but even at low volume the low end is much better than with the Crown XLS602 I temporarily used so far. I know it's a totally different league power-wise, but I wasn't anywhere close to the limits of both amps when I compared them.
So, if the decision is going to be between the Behringer and a Crown, I'd say go with the Behringer unless you know for sure that you can turn off that subsonic filter in the Crown. I'd recomment the t.amp over the Behringer, but I doubt that you can get them in the USA.
