(Message); it seems you are under-powering the MRX525's. These are rated at 1600 watts per ch. @ 4-ohms and the XTi 2000 is only delivering 800 watts per channel. With a power amp providing at least the recommended minimum output level, you are far less likely to experience blown drivers. The Crown XTi 6000 would be the logical choice if you want to stick with the Crown XTi Series amps. Having headroom in the power amp will let you operate the system more efficiently and you should also hear improved overall sound quality.It's usually not the high level of power that destroys drivers, but the distortion from a low-powered amp.

What other gear do you have? Do you use an EQ with "smilly face" curve?
Engaging the limiter and playing music at a level that the limiter engages, actually raises the average energy the speaker is getting causing extensive heat buildup in the speakers, the woofers can take it but the tweeter can't... When the limiter on the older XTI engages it does it in a very audible manner, you should be noticing it unless it almost never disengages, people say it sounds like shattered glass, do you hear it?
Also when setting the limiter at -3dB setting you essentially have a 400W amp and not even the 800W you thought you had
