Cerwin Vega XLS-215

I am looking into getting the Cerwin Vega XLS-215 but they need lots of power. Need advice for some 2 channel amps with a rating of 500 watts per channel or more.



The Cerwin Vega XLS-215 is rated 6 ohm. I have the Denon AVR-X7200WA receiver but not powerful enough to run the XLS-215.


Thanks for any advice!

You could go with a pro amp like this Crown or QSC with plenty of power to drive those Cerwin Vegas. They do have fans so be good to have them tucked away from listening area if possible. There are quieter fans folks have installed to help with that.

or a beast of a home audio amp like this Emotiva

Is it possible to take the cooling fan out? If the amp is in a well ventilated area, there is no need for a cooling fan.


Here is another amp I found but not sure about their quality:

They are really meant to and designed to have a fan running and if temp rises. Even in a well ventilated area it could overheat. The best option is to go with a quieter fan. How big is the room? These speakers are pretty efficient and will get very loud with with much lower than their max input wattage rating.

The Behringer is probably on par with the others. Many here use them for sub amps with good success and whole threads about them exists so search the forums.

That is a pretty big room but those speakers are pretty much pro audio type speakers and efficient . The amps might not get warm enough for the fans to turn on. Might have to just try it out and if too noisy see about replacing with quieter ones or setup some quiet fans blowing on the amp so the internal ones won't need to come on. That is a beefy Denon and might just work without an amp if you are just using it to drive these two speakers at 150W per channel. Are you setting up a home theater or just need some very loud speakers for an event?

Why? They're 95dB efficient and IIRC from the measurements I saw a while back have a fairly benign impedance.


A powerful, quiet (has fans but they will never come on in home use) are the Yamaha P-S series, recently replaced by the PX series so there should be clearance stock cheap. I'd suggest the P3500S.

If you want an amp with 500 watts a side, check out the Crown K2. has no fan, the price is right on this ad too, his shipping however, is way overpriced.

Most of these amps don't have the RCA connectors. I only see XLR connectors on the back. Is there a way to connect to the receiver? The Denon receiver can only use RCA cables.

Both the Crown and QSC I linked to have RCA inputs, 1/4" inputs and XLR inputs. Check the pics of the backs and you will see them.

They make cables with xlr on one end and rca's on the other.

Crown's newer pro amps do have RCA's for easier connection, as do some others as well, I assume. It is quite possible that the fans in these amps will rarely turn on in a home environment.
