Proficient C641 Ceiling Speaker

Proficient Audio

  • The 2-way Ceiling Mountable speakers provide the finest sound coverage
  • Uproar the bass as loud as you want with 125 W RMS power without any blaring
  • Hear every detail crisp and clear with a frequency response of 32 Hz-22 kHz


The C641’s grille conceals tone switches that let you boost the bass and/or treble by 3 decibels. With the flick of a switch, you can kick up the lows or highs to suit your taste. No matter how you set the switches, you’ll love the C641’s sound, thanks to its low-distortion graphite woofer and aluminum tweeter.

No subwoofer needed here, because the C640 plays down to 32 Hz. That’s 9 Hz below the deepest note on the upright bass! The 92 dB sensitivity means the C641 needs only about one-third as much power as a typical speaker, so you can get satisfying sound even with very low-powered amplifiers. A sturdy dogleg mounting system makes it easy to install.
