Wow .. great product

By Ken Pool

from Linden, Michigan

To be honest, I wasn't a fan of crown until I purchased a crown 1200 a while back. It was ok, but nothing to write home about. This crown, however, is phenomenal! The DSP hardware is great, the amps weight is incredibly light, and the performance is very impressive. The only issue I had with the device was the manual on the user interface. It was a little cryptic when it came to running the amp in bridged mono mode. Very nice product .. I will definitely be buying another one!

All other amps bow down!

By gguillo

from Little Rock, AR

I am not sure if it gets much better than these amps! We use four of these bridged for (2) JBL SRX 722s and (2) JBL SRX 728s. Bridged mode @ 3200 watts @ 4 ohms is the truth! Super clean power, no noise and a damping factor of >500! The crisp highs, the clarity of the mids, and the punchiest of lows makes this amp a winner in my book! Also, it says they weigh in at 17 lbs. I think it's more around 12-13 lbs. These are very light and super easy to transport.

Excellent built in features

By Adam

from Cincinnati, Ohio

Not sure why you'd buy anything else. Built in high/low pass crossovers, tons of options.. Load it up on your computer to get the full value out of it. Tons of power, super light-weight, and extremely versatile.

Great amp, Awesome weight

By CMG

from Summerville, SC

These are awesome, their built-in DSP is a great feature for anyone who doesn't want to lug around a lot of outboard gear. I like them much better than the QSC PLX's, these push my subs/mains to be louder than the PLX's, and they still sound much clearer. Overall a great amp with a awesome weight. 5 Stars.

Nice amp with great power and light weight

By Poboy

from Texas

I just purchased two of these amps to power a couple of JBL SRX722's. Bridged mono these monsters put out 3200W @ 4 Ohms. They are so quiet and the onboard DSP is really nice. Also, the weight makes for a lighter rack which is real nice loading out. I would recommend these to anyone who wants quality and power.
