Product Description
The Klipsch RP-1400CSW is a 14-inch Reference Premiere compact subwoofer. Its sealed cabinet takes up about half the floor space of a full-size Reference Premiere subwoofer, yet a front-firing Cerametallic woofer and a 500W RMS (1000W peak) Class D amplifier reach down to 15Hz with up to 121dB of output for movies, music and gaming.
Coming soon: new for fall 2026, expected to ship in late November 2026.
All the Bass in Half the Space
Klipsch designed the Reference Premiere Compact Subwoofers for today’s living rooms, media rooms and dedicated listening spaces. The sealed enclosure occupies about half the footprint of the full-size RP subwoofers, so it is easier to place, while extending the low end of your system by up to one octave.
High-Excursion Cerametallic Woofer
A 14-inch Ultra Long Throw Cerametallic™ woofer fires forward from a rigid MDF acoustic suspension (sealed) cabinet, for clean, articulate bass with real depth and impact.
Class D Power with an Analog Preamp
A precision analog preamplifier stage feeds a high-efficiency Class D amplifier rated at 500W RMS and 1000W peak.
Easy Tuning
Rear-panel crossover, phase and gain controls have high-contrast labels, so they are easy to read while you set up. And yes, the gain control goes to 11.
Wired and Wireless Connections
Connect with the dual RCA / LFE line-level inputs, or add the optional Klipsch WA-2 Wireless Subwoofer Kit (sold separately) for more freedom in where you place the subwoofer. The RCA and wireless inputs work at the same time, so one subwoofer can serve more than one system in the same room.
Reference Premiere Styling
A scratch-resistant Ebony vinyl finish, copper accents, rounded cabinet edges, shock-absorbing rubber feet and a floating fabric grille match the rest of the Reference Premiere family.
