Description
Put the Subwoofer Where the Room Needs It — Not Where the Cable Ends
The RXSB5 creates a dedicated wireless audio connection between compatible audio equipment when running a long RCA cable is difficult, impractical or unwanted.
Connect the transmitter to a subwoofer, LFE or line-level output, then place the receiver beside a powered subwoofer, powered speaker or remote amplifier. The audio signal travels wirelessly while your receiving equipment continues to use its normal AC power.
| Dedicated 5.8GHz Link | Up to 100 ft / 30 m* |
| RCA Stereo Audio | 20Hz–20kHz Full-Range |
*Maximum advertised distance is based on clear line-of-sight conditions. Actual wireless range depends on the installation environment.
What Problem Does the RXSB5 Solve?
Finished Room — No Easy Cable Route
Add a powered subwoofer without routing a long RCA cable across the floor, through a finished wall or around doorways.
Subwoofer Needs a Better Location
Move a compatible powered subwoofer away from the AV receiver when another location works better for the room layout.
Remote Powered Speaker or Amplifier
Send full-range stereo line-level audio to compatible powered speakers, active monitors or another amplifier in a difficult cable location.
Temporary or Flexible Installation
Useful where equipment may be moved or the space may be reconfigured without installing permanent signal wiring.
Home Audio Applications
• Home theatre powered subwoofer connection
• Media rooms and basement entertainment spaces
• Condos and finished rooms where new cable routing is difficult
• Powered stereo speakers positioned away from the audio source
• Stereo or AV systems that may be rearranged later
Commercial & Professional Applications
Boardrooms & Meeting Rooms: Send line-level audio to compatible powered speakers or a remote amplifier where installing a new signal cable is difficult.
Retail Displays & Showrooms: Create flexible audio demonstration areas without permanently routing analogue audio between display locations.
Reception & Waiting Areas: Send background or display audio to compatible powered equipment at another location in the room.
AV Demonstration & Training Spaces: Useful for temporary equipment layouts where the audio source and receiving system may change location.
Remote Amplifier Connection: Carry a line-level signal from a mixer, streamer or compatible source to an amplifier positioned elsewhere.

| Solution | Best Use | Choose It When |
|---|---|---|

| RXSB5 | Wireless Line-Level Audio | You need to send subwoofer or full-range line-level audio to powered equipment without a long audio cable. |
| RXS5 Wireless Audio Kit | Wireless Rear Speakers + Subwoofer | You need speaker-level functionality and a receiver with a built-in stereo amplifier for compatible passive rear speakers, plus subwoofer line-level support. |
Why a Dedicated 5.8GHz Audio Link?
The RXSB5 transmitter and receiver are designed to communicate directly with each other. No Wi-Fi network, app, account or Bluetooth pairing with a phone is required.
Because it is a dedicated audio connection, setup remains focused on one job: moving a compatible analogue audio signal from the source to the receiving equipment. As with any wireless system, actual performance depends on the building and RF environment.
