The RP221 Bottom Feeder from Rolls is designed for DJs and karaoke applications, and provides enhanced low-end sound along with high-end clarity.

The unit utilizes all-pass filtering, frequency compensated gain adjustment and compensated frequency domain delay to reduce the need for high volume and radical equalizer adjustment.

A sub-octave synthesizer divides the low frequency portion of the signal (the frequencies below the crossover point) in half, providing an extreme bass sound.

      Comments about Rolls RP221 Bottom Feeder Crossover:

      You won't see this at the bottom of my list. Another piece of equipment from Rolls with a small footprint and many features. A novice may have a litle problem setting it up, but will have no problem using the "Bottom Feeder". Again, Rolls produced a small durable unit for a small price, without scraficing quality. This could be part of a small inexpensive home theatre system for those not wanting surround sound, but want a little kick.

      Comments about Rolls RP221 Bottom Feeder Crossover:

      I have a kenwood home receiver w/ sub output, and a QSC plx3002 PA amplifier. I bought bottom feeder to drive the amp a little harder. the bottom feeder does what it says "but" if you put the levels anything past 0db the sound is not as clear as I would have expected..

      good for live sound / D.J. / events
