Klipsch WA-2 Wireless Subwoofer Kit

Powerful bass is great—powerful bass placed exactly where it performs best is even better. The Klipsch WA-2 Wireless Subwoofer Kit adds simple, reliable wireless capability to compatible subwoofers with a dedicated “WA Port,” letting you send low-frequency effects (LFE) and bass information from your AV receiver/processor (or a stereo receiver with line-level outputs) without running a long, bulky subwoofer cable across the room.

This two-piece system (transmitter + receiver) is designed for easy plug-and-play operation: complete the quick first-time sync and the system is ready to automatically activate when you want to listen. With 2.4GHz operation, automatic channel selection, up to a 50 ft (15 m) signal range, and a frequency response built for deep bass content, the WA-2 makes cleaner installs and optimal sub placement far easier—especially in home theater, music, and whole-house audio setups. Use up to four WA-2 kits in an average-size household for flexible multi-room or multi-sub configurations (with compatible WA Port subwoofers).

What It’s Great At:

• Enabling wireless subwoofer placement for smoother, more accurate bass in the room
• Replacing long subwoofer cables for cleaner, simpler home theater and music setups
• Quick, hassle-free setup with automatic pairing behavior after the first sync
• Maintaining stable performance with 2.4GHz operation and automatic channel selection
• Supporting multi-sub or multi-zone layouts (use up to four WA-2 kits in an average-size household)
• Fine-tuning input levels with transmitter gain control for better compatibility across receivers/processors

Klipsch WA-2 Q&A:

What does the Klipsch WA-2 Wireless Subwoofer Kit do?

It wirelessly sends bass/LFE signal from your receiver or processor to a compatible WA Port-equipped subwoofer, reducing the need for a long subwoofer cable.

Will the WA-2 work with any subwoofer?

No. It only works with select Klipsch, Energy, Mirage, and Jamo subwoofers that have a dedicated “WA Port” input.

What’s the wireless range of the WA-2?

The system is designed to transmit up to a 50 ft (15 m) radius, helping you place the sub where it sounds best.

Does it require complicated setup or software?

No. It’s designed for plug-and-play use, with a simple first-time sync and automatic operation afterward.

Can I use more than one WA-2 kit in my home?

Yes. Up to four WA-2 kits can be used simultaneously in an average-size household (with compatible WA Port subwoofers).

What’s included in the box?

You get a transmitter, receiver, power supply, audio cable, Velcro strips, and the owner’s manual.

How do I connect it to my receiver if I don’t have a dedicated subwoofer output?

If your stereo receiver has line-level left/right preamp outputs, you can connect those to the transmitter inputs as an alternative.

What is the gain switch for, and how should it be set?

The gain switch helps match different receiver output levels; 0 dB is the recommended starting position, with -12 dB or +12 dB available for fine-tuning.
