The Goldwood GR-800 ceiling speaker is a great addition to any home theater or listening room. It is designed for both whole house audio and surround sound applications. It features an 8" woven Kevlar woofer to deliver hard hitting bass and smooth mids. The pivoting 1" silk and Titanium dome tweeter reproduces crisp, clear highs by using a 12 dB crossover with a Mylar capacitor. The tweeter also has a +3/-3 dB level adjustment that allows it to fit into any room environment.
