Recently I've been clipping my denon more than I'd like. I'd like to find a decent amp for my l/c/r and the crown Xti 1002 with dsp looked appealing. I searched through the forum and no one had anything to say about this line of amps.

Any thoughts? What are you guys using to power your front stage?

I like to two XTi 2002s I have running each of my subs. I don't have much experience with many of the other "pro" amps. I really like the built in EQ and the simplicity without having to add another device in the chain.

With that said, there are much more intelligent people in here that could chime in with their wealth of experience with the various amps.

As for my front stage, I am running a 5 channel Fosgate Audionics amp. It's been good to me for many years, though I wish it had XLR inputs.

I don't like my XTI 4k's on subwoofer useage, not powerful enough, kept clipping and overheating them.

(Not sure about the 6000, it's Class-D so probably much better.)

I'd stick with a Lab clone or a EP4k/nuDSP if I were you.

My personal 2 cents.

I was told by a Crown rep that they have an undefeatable 24db high pass at 20hz. Nowhere have I been able to find anyone who has measurements or any type of hard evidence. I just traded my xti2002 for an EP2500 and miniDSP to get low extension below 20hz. I didn't get my umik-1 yet to measure the crown, so I don't have real evidence either.

I would look elsewhere for a sub amp, but I'm no expert.

Domanskipaul- are you talking about using this amp for powering your subs or main LCR's? I have read that these Crown XTI amps are similar to the Behringer iNukes in that they roll off at 20hz, but I would imagine that they work great for powering your Left/Center/Rights in a theater type setting.

I have actually considered selling my Behringer EP4k's that I currently use to power my mains, and replacing them with a pair of XTI-1002 or iNuke 1000dsp. I am interested in hearing what other folks have to say about this...

I used to run a Crown XTi1000 for L-R duty and the sound was just fine and could handle the volume I needed. I eventually switched to a QSC GX5 and am very happy with it. One thing I liked about the Crown was the variable speed fan, if it did kick on the music was loud enough for me never to hear it.

Marty - Maybe I wasn't clear in my first post, but yes I do mean powering l/c/r. I was actually thinking about picking up 2 of the 1002 for lcr and a 4002 for sub duty. Has anyone seen any tests on these amps to confirm the 20hz high pass on the entire line?

Thanks for everyone's feedback so far.

I just wanted to add that I spoke with a Crown rep a couple of days ago and he also mentioned that the amp nose-dives at 20hz.

The odd thing is that when I run a 10hz sine wave through it I still get palpable output so I don't know how steep it really is.

Great amps. XTi-1000 runs my mains, XTi-2002 runs my subs. The fan stays off 99% of the time and the system never, ever falters. The XTi-1000 is about six years old, still functions perfectly.

After swapping in an EP2500 for my XTI2002 and making no other changes I noticed an increase in <20hz output. I like the EP quite a bit more, I would buy a XTI2 again, just not to power any subs.

Once again I'm not an expert and have no measurements to back this up. Just my ear and some quick listening over the weekend. Even the GF noticed it sounds better.

That's surprising, because unless you were clipping the XTi-2002, the two amps should sound identical. It's just my personal guess, but perhaps your system benefited from re-EQing? I've directly compared an EP4000 to an XTi-2002 and aside from ultimate power handling, there was no difference to hear once the amps were level-matched.

No clipping, no re-EQing involved, I simply swapped amps, set the EP to 75db as I did previously with the XTI. I was even able to find some new rattles in the house with my newfound lows. That in itself is evidence to me.

I think the XTI was able to produce the same frequencies, just not with any meat behind it.

His observation is almost certainly correct if indeed the Crown has the 24db slope at 20hz like the Crown tech told me. It (the EP 4000) would "sound" better in the respect that it is producing output that the xti was not- just as he said. And after re-running the 10hz waves and then the 20hz I found the difference in output was readily apparent. I'm now all but certain the xti's are not doing much below 20hz. Still great amps for apps that don't require such LFE's though.

I called Crown and confirmed that all Crown amps have a high-pass filter at 20Hz, and historically that's been set at 24bd/octave. Shockingly, when I told the tech the intended use was for subwoofers, he said "most people's speakers don't go below 30Hz anyway". Most unfortunate. Looks like I'm in the market for a new subwoofer amp.

Deja vu, post #4 above....
