The C870 LCR home theater ceiling speaker from Proficient Audio Systems extends the company’s LCR series into high-end home theater systems for new custom homes. The principal design highlight is that the woofer and tweeter bridge are set at a 15-degree angle while the tweeter pivots another 30 degrees. This allows the installer to direct critical mid-range and high frequencies at the sweet spot listening area. Proficient Audio Systems
