The built-in, high-efficiency 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.


Cerametallic woofers are exceptionally light and extremely rigid, providing a remarkable low-frequency response with minimal cone breakup and distortion for higher, cleaner output using less amplifier power.


Klipsch Cerametallic cones are matted to a dual-layer, copper-wound voice coil for exceptional conductivity. Reference Premiere woofers are housed in a non-resonating, stamped-steel basket that’s secured to a large magnet motor for exceptional efficiency and low distortion, and matched to our horn-loaded tweeters for optimal acoustic execution.


Klipsch SPL subwoofers leverage proprietary internal-flare geometry that 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.


Low Pass Crossover and Variable Phase control allows you to tune the subwoofer to your Klipsch speakers and to your room, establishing the ideal level of bass. Line Level / LFE RCA inputs ensure compatibility with home theater receivers. Both the RCA and wireless inputs can be utilized, giving you the ability to use a single subwoofer with multiple systems in the same room. For example, you can use the wireless input for your home theater set up and the RCA input for your 2-channel system, without needing to switch inputs when changing between systems.


Klispsch SPL subwoofers feature a scratch-resistant ebony finish that looks like real wood and covers the entire cabinet. Shock-absorbing rubber feet, steel grille posts and a woven cloth grille give the SPL subwoofers a premium look and feel.
