Klipsch Reference Premiere SPL-120 Powered Subwoofer 300 W Home Theatre  (Black, Mono Channel)

Features 12" Cerametallic Woofer: The Klipsch SPL-120 powered sub houses a front-firing 12" Cerametallic woofer for deep accurate bass. Cerametallic consists of extremely light, rigid materials that can hold shape while being able to deliver lower frequencies with maximum efficiency. The Klipsch Cerametallic cone is matted to a dual-layer, copper-wound voice coil for exceptional conductivity. The 12" woofer is fixed to a non-resonating, stamped-steel basket that's secured to a large magnet motor for exceptional efficiency and low distortion. 200W Class D Amplifier: The 12" woofer is powered by a built-in 300W (RMS)/600W (Peak) Class D amplifier. The high efficiency Class D amplifier features an analog preamp design, which maintains the original signal path for cleaner, true-to-source reproduction. The Class D output stage ensures maximum efficiency for maximum output, detail, and low frequency power. Front-Firing Port: The Klipsch SPL-120 powered subwoofer features a front-firing port for greater efficiency, bigger bass response, and flexible placement. Proprietary internal-flare geometry minimizes port noise for clean undistorted low frequencies. The front-firing design allows for placement flexibility to reduce unwanted resonance from your walls or furniture behind the subwoofer. MDF Cabinet: The Klipsch SPL-120 powered sub features a MDF cabinet with a scratch-resistant, textured wood grain vinyl that seamlessly integrates into almost any room or decor. The enclosure's reinforced MDF construction reduces cabinet vibration for less audible coloration and improved sonic accuracy. Shock-absorbing rubber feet on the bottom of the cabinet to help isolate the subwoofer from your floor. The included wove cloth grille adds a refined look and is acoustically transparent. Controls: The level control, low pass crossover, and phase control allow you to blend the powered subwoofer's low-frequency tones with your system's other speakers, as well as establish the ideal level of bass. All controls are found on the rear-panel of the powered sub. Level Control: The level control adjusts the subwoofer's volume relative to the rest of your home audio system. After the sub's level control has been set, the volume control of your AV receiver will be the volume control for both the Klipsch powered subwoofer and your connected loudspeakers. Low Pass Crossover: The variable low pass crossover is adjustable from 40-120Hz. The crossover point chosen determines where low bass frequencies are "handed-off" from your AV system's loudspeakers to the Klipsch powered subwoofer. Set the crossover point based on the size of your systems' main left/right speakers. Phase Control: This control is used to acoustically match the subwoofer's output to your main speakers. Select the position either 0? or 180? in which your subwoofer has more output at the listening position. Connections: The Klipsch SPL-120 is equipped with line-level inputs that can be used as a stereo RCA input or LFE input. There is also a proprietary wireless input for connection of Klipsch's W-A2 Wireless Subwoofer Kit (sold separately). LFE/RCA Input: Most of today's AV receivers have a line-level subwoofer output (LFE). If your receiver has an LFE output, connect one end of a subwoofer cable (sold separately) to this output and connect the other end of the cable into the powered subwoofer's line-level input labeled "LEFT/LFE". Set the powered sub's built-in crossover to "LFE" with this type of connection. In the absence of a subwoofer (LFE) output on your receiver, as an alternative hookup, you can connect Left & Right channel pre-amp outputs from the receiver to both the "Left/LFE" and "Right" inputs on the powered subwoofer. Optional Wireless Subwoofer Kit: The Klipsch WA-2 Wireless Subwoofer Kit (sold separately) allows high resolution wireless connectivity between the SPL-120 powered subwoofer and your AV receiver.
