A super-stiff, 8-inch graphite woofer gives the C841 an especially natural-"yet powerful-"sound. The woofer and tweeter are angled 15 degrees, allowing you to put the speaker in the ceiling up by the screen while directing the sound at the listeners. You can even pivot the tweeter to get it aimed just right. The C841 gives you the great sound of graphite in a hideaway home theater speaker. Its 8-inch graphite woofer has an incredibly stiff cone for low distortion and powerful bass all the way down to 40 Hz. Proficient's sophisticated 1-inch silk dome tweeter blends perfectly with the woofer, delivering clear, sweet highs to complement the powerful lows.
