WSA-5RP Wireless Surround Sound Rear Speakers Kit - Stable Lossless

Our review of the WSA-5RP Wireless Surround Sound Rear Speakers Kit finds it best for homeowners and home theater hobbyists who want a tidy way to add rear surrounds without running long speaker cables. The single biggest reason to buy is the dual-band 5.2 / 5.8GHz wireless link with 106 RF channels that minimizes interference and delivers near lossless audio, so the rear channels remain clear and stable even in WiFi-heavy environments. Setup is straightforward and it integrates with existing A/V receivers via speaker line level or stereo RCA inputs.

Key Features

• Dual-band lossless link: The selectable 5.2 and 5.8GHz wireless transmission with 106 RF channels reduces WiFi interference and preserves near lossless 24-bit 48kHz audio quality for rear channels.
• Built-in amplification: Two Class D amplifiers provide 2 x 25W RMS at 8 ohms (or 2 x 50W RMS at 4 ohms) so these units can drive passive bookshelf or surround speakers directly without extra amplifiers.
• Receiver-friendly inputs: Speaker line level and stereo RCA inputs let the kit accept full-band audio from an AV receiver, preamp, or external amplifier for flexible integration.
• Subwoofer passthrough: A mono subwoofer input and output are included to insert a powered subwoofer or subwoofer amplifier between the AV receiver and speakers for better low-frequency management.
• Long range operation: Line-of-sight range up to 100 ft (30M) supports typical living-room and medium-size home theater layouts without signal dropout.

Who It's For

The WSA-5RP is ideal for users who want to upgrade a two-channel or front-focused system into a surround setup without running long rear speaker cables across a room. It suits apartment owners, media rooms, and anyone concerned about WiFi interference who needs a stable wireless link for rear channels.

It is less suitable for audiophiles who demand fully wired, reference-grade multi-channel systems or for installers who require multi-room distributed audio with centralized amplification. Also, buyers who already have active wireless rear speakers may find fewer advantages compared with passive speakers driven by this kit.

Pros & Cons

Pros

• Reliable near lossless wireless transmission with selectable dual-band operation that minimizes interference.
• Built-in Class D amplification lets you connect passive surrounds directly without separate amps.
• Flexible inputs and subwoofer passthrough make it easy to integrate with most AV receivers and powered subs.

Cons

• Some customers reported occasional pop noise during certain conditions, so sensitive systems may need careful testing.
