Klipsch RP-1200SW Q&A:

It combines a 12" ultra-long-throw Cerametallic™ driver with a 400W RMS / 800W peak Class D amplifier to deliver deep extension down to 16.5Hz and high output up to 121dB for cinematic impact.
How do I connect the RP-1200SW to an AV receiver?
Use the receiver’s subwoofer/LFE output into the subwoofer’s L/LFE input, or connect left/right pre-outs to the L/LFE and R inputs when needed.
Does the RP-1200SW support wireless connectivity?
Yes. It includes a WA-2 wireless port for the optional Klipsch WA-2 Wireless Subwoofer Kit (sold separately), allowing easier placement without running a long cable.
Can I use both wired and wireless inputs at the same time?
Yes. The design allows RCA and wireless inputs to be used simultaneously, which can be useful if you want one subwoofer available to more than one system in the same room.
What do the low-pass and phase controls do?
The Lowpass control helps blend the subwoofer with your speakers by setting where bass hands off, while the 0/180° phase switch helps align bass timing for stronger, smoother response at your listening position.
What is Auto standby and how does it work?
In AUTO, the subwoofer turns on when it senses a signal and drops into standby after about 15–20 minutes without a signal for convenient everyday use.
Is placement easier with this subwoofer design?
Yes. The front-firing driver and front Aerofoil slot port support flexible placement while helping keep bass clean and controlled.
What are the size and weight for planning cabinet or room placement?
The cabinet measures 18.89" (H) x 17.00" (W) x 25.92" (D) and weighs 68.6 lbs, so plan for a stable surface and enough clearance for easy access to controls and connections.
