Klipsch The Sevens are self-powered Heritage-inspired stereo speakers that blend Klipsch's legendary horn-loaded sound with everything needed to anchor a modern music and Tv room. A 200-watt Class D amplifier drives a 1-inch titanium horn tweeter and 6.5-inch woofer per cabinet. Hdmi-arc, optical, Usb-b, analog, phono, and Bluetooth 5.0 inputs cover every source. Real-wood veneer cabinets in black finish the look.
