Proficient Audio C621
A 1 inch silk dome tweeter gives the C621 an especially sweet and detailed sound, perfect for those who seek a higher level of musical truth. The tweeter pivots so you can direct the sound wherever you need it. The tough 6½ inch polypropylene cone woofer plays down to 45Hz - as deep as some big tower speakers can play.
With 91dB sensitivity, the C621 puts out an incredible amount of sound from even a 10 watt amplifier. It has an 8 ohm nominal impedance, which makes it easy to drive with any amp you might want to use. For your convenience, it uses the same cutout template and sturdy dogleg mounting system as all of Proficient's other 6½ inch ceiling speakers.
Includes Thin-Bezel Grilles held by Neo Magnets.
