    Crowns XLi: New amp (home audio level friendly)

    Crown released a new series called the XLi. It lacks the X-Over and Limiter functions and adds true .775 sensitivity (user selectable between .775 and 1.4 volts). So should be friendly to consumer AVR's and DACS.

    Prices start at $249 for 200WPC at 8 and 300WPC at 4 but I believe they are 1 Khz ratings.Name:  xti.jpg

    Looking at the specs, they seem perfect for DJ and sub use but to power the main speakers (LCR) I would look elsewhere.

    One question: Why do amp manufactures use that ridiculous power rating at 1khz?

    It's a pretty common reference, although I am not sure why they choose that standard. My issue would be that it produces 0.5% total harmonic distortion with that reference tone. It would lead me to believe the THD would be greater at different frequencies.

    Despite those who swear by using a "commercial sound reinforcement" amp in a home theater or music system, I am somewhat skeptical. For movies sure, but many of these amps are pretty noisy, both fan noise and an increased noise floor.

    For subs, I would do it as long as the amp didn't drastically roll off on the lower end of the frequency curve.

    I think for a few $$'s more the XLS and XTi series 2 would be a much better choice.

    I'm one of those guys that use a commercial / pro amp. I even dumped my Parasounds and Adcom amps in the bargain. Just like anything else you have to do your own due diligence. My Parasounds had a higher noise floor than my XLS 402D.
