Shake the Foundations (If You Want): Klipsch SPL-150 Powered Subwoofer Plays with Major Depth and Impact, Features 15-Inch Cerametallic Woofer and 122dB Maximum Output
Weighing in at more than 75 pounds, the Klipsch SPL-150 powered subwoofer is a bad, bad musical instrument. The aural equivalent of a military-grade depth charge when added to either a two-channel or surround-sound system, it will ensure you never lack for serious bass, low-end extension, and explosive impact again. And while it's fun to talk about SPL-150's foundation-shaking prowess, particularly when paired with any of the company's Reference Series loudspeakers, it's equally practical to talk about the audiophile technology and components inside that allow it to be far more capable than just delivering boom-and-sizzle fireworks.
The 21.5 x 19.5 x 22.3-inch (HWD) SPL-150 leverages the technological advantages of a highly efficient amplifier with analog preamplifier stage and a 15-inch, long-throw, spun-copper Cerametallic woofer matted to a dual-layer, copper-wound voice coil to play with clean, rich, detailed sound. A front-firing slot port with exclusive internal flare technology that leads to easy placement, low-pass crossover and variable phase controls, and the ability to simultaneously utilize both the RCA and wireless inputs speak to SPL-150's user-friendly design. Compatible with Klipsch's optional WA-2 wireless subwoofer kit, SPL-150 also looks sharp thanks to its ebony finish, shock-absorbing feet, and woven cloth grille.
If you're ready to experience how a subwoofer can dramatically change what you feel and hear, SPL-150 is certain to please. 100% Music Direct Guaranteed.
"And while the 150 uses an amplifier that puts out "only" 400 watts (800 watts peak), the efficient vented design means it sounds much bigger than it is. Phase, low-pass and gain controls help tailor the sound to perfection. This is a great choice if your audio system will have a lot of focus on music."

Front-Firing Cerametallic Woofer
Cerametallic woofers are exceptionally light and extremely rigid, providing remarkable low-frequency response with minimal cone breakup and distortion for higher, cleaner output using less amplifier power.
The built-in, high-efficiency amplifier features an analog preamp design that 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.
Slot Port with Internal Flare Technology
Proprietary internal geometry that minimizes port noise for clean undistorted low frequencies. The front-firing design allows for placement flexibility.
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.
Simultaneously Use Both Inputs
Both the RCA and wireless inputs can be utilized, giving you the ability to use a single subwoofer with multiple system in the same room. For example, you can use the wireless input for your home theater set up and the RCA input for your two-channel system, without needing to switch inputs when changing between systems.
Shock-absorbing rubber feet, steel grille posts, and a woven cloth grille give SPL subwoofers a premium look and feel.
