Cinergy 5.1

About the Cinergy 5.1

The Joseph Audio Cinergy 5.1 (often seen as Cinergy 5.1 II in later listings) is a passive center channel loudspeaker intended for use as the center in a 5.1 or larger home theater surround system. It is a two-way, vented-box design using one 1-inch silk-dome tweeter flanked by dual 6.5-inch aluminum-cone woofers, configured to deliver wide horizontal dispersion and clear dialogue over a broad listening area. The cabinet is large and heavily built, typically finished in real cherry wood veneer, and includes dual binding posts to allow bi-wiring. Reported specifications from reputable resale listings and user documentation indicate a frequency response of approximately 37 Hz–20 kHz (±2 dB), nominal impedance of 8 ohms (minimum about 6 ohms), sensitivity around 86 dB (1W/1m), and power handling up to about 200 W, making it suitable for high-quality home cinema when paired with capable amplification and subwoofer support. It is part of the older Cinergy home-theater range from Joseph Audio and is no longer in current production, but remains valued for its smooth, coherent presentation and strong integration with matching Joseph Audio mains and surrounds.
