Know before you buy
This design helps eliminate the uneven sound distribution often found in horizontal center channel speakers. It ensures that dialogue remains clear and consistent, even if you are sitting off-center from the screen.
It is quite efficient with a 91dB sensitivity rating, meaning it can be driven well by most standard home theater receivers. We recommend an amplifier capable of delivering between 15 and 150 watts to get the best performance.
This tweeter uses a pleated diaphragm to move air more efficiently than a traditional dome tweeter. It provides high-frequency detail and clarity, which is essential for making movie dialogue and subtle sound effects stand out.
Yes, the speaker includes Secure-Lock Grilles that are designed to be easily removed. This allows you to customize the aesthetic of your setup while keeping the drivers protected when the grilles are attached.
Yes, the C1 is specifically voiced to match the other speakers in the Foundation Series. Using them together ensures a seamless, uniform soundstage across your entire surround sound system.
The speaker measures 7-5/8 inches high, 20 inches wide, and 10 inches deep. It is a relatively compact center channel, but you should measure your console's shelf space to ensure it fits comfortably with room for cable connections.
