Line Circle
The Klipsch RP-1400SW is a high-performance 14-inch powered subwoofer built to deliver deep, accurate bass for home theater and music systems. Its 500W RMS / 1000W peak Class D amplifier with an analog preamp stage drives a 14" ultra long throw Cerametallic™ woofer for clean output and serious impact. A front-firing Aerofoil slot port reduces turbulence for tighter, more controlled low frequencies and easier placement. With dual RCA/LFE inputs and optional WA-2 wireless compatibility, it’s an ideal upgrade for Reference Premiere and other premium speaker setups.

Features & Specs Line Circle

4" Ultra Long Throw Cerametallic™ Woofer
A rigid, lightweight cone structure helps the driver move serious air while staying controlled, reducing distortion and keeping bass clean at higher volumes.
500W RMS / 1000W Peak Class D Amplification (Analog Preamp Stage)
The efficient Class D power section delivers strong output with headroom, while the analog preamp stage helps preserve signal integrity for true-to-source bass.
Deep Extension: 16Hz–141Hz (±3dB)
Reaches into the lowest octaves for cinematic rumble and low-end texture, while still maintaining attack for kick drums and bass lines.
Front-Firing Aerofoil Slot Port
Designed to minimize turbulence and port noise, helping the sub sound tighter and cleaner—especially during demanding scenes and bass-heavy tracks.
Flexible Connections (Dual RCA/LFE + WA-2 Port)
Integrates easily with AV receivers via LFE, supports stereo pre-outs when needed, and enables optional wireless placement with the WA-2 kit.
Room-Tuning Controls (Low Pass + Phase)
Makes dialing in a smooth blend with your speakers straightforward, improving cohesion, impact, and overall bass balance in your room.

Klipsch RP-1400SW Q&A:

What kind of room is the RP-1400SW best for?
It’s an excellent fit for medium-to-large rooms where you want deep extension and high output, especially for home theater impact and full-range music listening.
Can I connect it to an AV receiver using an LFE/Sub Out?
Yes. Use the receiver’s Subwoofer/LFE output into the RP-1400SW’s L/LFE input for the most common home theater connection.
Does it work with stereo preamps or receivers without a dedicated sub output?
Yes. If your system provides left/right pre-outs, you can connect both channels to the subwoofer’s RCA inputs.
Can I place the subwoofer anywhere in the room?
The front-firing driver and front slot port make placement more flexible than many rear-ported designs. Corner placement often increases bass output, while mid-wall placement typically reduces it.
Does the RP-1400SW support a wireless connection?
It supports wireless operation using the Klipsch WA-2 Wireless Subwoofer Kit (sold separately) via the built-in WA-2 port.
What do the low pass and phase controls do?
The low pass (crossover) control helps blend the subwoofer with your speakers by setting where bass is handed off to the sub. The phase switch (0°/180°) helps align bass timing for stronger output at your listening position.
Will it automatically turn on and off?
Yes. In Auto mode, it turns on when it detects a signal and enters standby after roughly 15–20 minutes without signal.
Can I use multiple inputs at the same time?
Yes. The design allows simultaneous use of inputs (for example, one connection for home theater and another for a 2-channel setup), depending on how your system is configured.
