A single 12" woofer and 1" tweeter give you full spectrum range to cover everything from bass to keys, guitars and vocals.

The K900FX also works as a great keyboard amp with its three stereo inputs.

Best keyboard amp

If you are looking for a keyboard amp this is the best , I am so happy with mine thank you sweetwater 5
Rated 5/5

Love It!

I've bought my Behringer Ultratone K900FX here at Sweetwater about a year ago to accompany my Roland keyboard for home use. I was mostly happy with my Roland keyboard buy it's small internal amp & speakers just didn't due justice to bass in the bottom octave. Adding this amp made the keyboard sound much more like a real piano, giving it strength and power everywhere in it's range. I don't think you can go wrong with this piece unless you need something larger and much more expensive for stage use.

Very Very Good

As I told my sales dude Jeremiah (who rules btw) this amp is amazing. I plugged my Cobalt 5s synth in, cranked the amp up to about 4, kicked the synth to its lowest octave range, and was completely blown away by the sound. Perfectly articulated and not boomy in the least. Then I plugged in my mic and blew saxophone. Again, amazing sound. If you're playing at home, or if you have a home studio, or playing a club, this amp is the ticket. For jamming, using it as a stage monitor, or for just practicing, this amp is fantastic. Quite unbelievable really how much you get for the price. And I've just begun to explore the effects. So glad I snagged this!

Absolutely perfect!

I needed something that didn't weigh a ton. I have a Roland KC 600 and A Peavey KB 300 and they're both way too heavy for small gigs. This Behringer is perfect. Easy to haul around and the real selling feature for me was the built in effects. These amps get used for Keyboards, Bass Guitar and Accordion and having the built in effects for accordion sold me. For my purposes this sounds great and fits the bill.
Music background: Been playing music for 67 years and still going strong
