Behringer K450FX

This super-compact, self-contained sound system is perfect for public address systems, keyboards, voice, or various drum/backing machines. 45 Watts of power are handled confidently by a headroom-rich 10" BUGERA speaker, making sure that you can faithfully reproduce a broad repertoire of signals. The only thing this keyboard amp is short on is an exorbitant price: we’ve included all the “must-have” features that you are accustomed to in much larger amps: 24-bit digital FX with 100 hot presets, our trademark FBQ Feedback Detection System, full 3-channel operation with separate volume controls and FX sends per each channel plus an additional XLR mic input for connecting dynamic microphones. You can rely on our 5-band EQ section to help you carve out perfect sound. In addition, there is a CD input plus a headphone output, giving you lots of choices you’d hardly expect in this price category. With BEHRINGER, you can simply expect more!

Great Bargain!
I bought this keyboard amp for my church, as we had small stereo speakers sitting on the keyboard which often got dropped. This amp really has a great tone and does the job. I thought about getting the slightly better model that had a larger woofer and had a tweeter, but then decided that we didn't need it and I was right. This amp filled the bill for the type of usage we have.
