The Marmitek Subwoofer Anywhere 640 is a dedicated wireless transmitter and receiver system for relocating an active subwoofer to any position in a room without running a cable from the surround amplifier. The transmitter connects to the subwoofer output of the amplifier; the receiver connects to the LFE/Line-In coaxial (RCA) input on the active subwoofer. Signal is transmitted digitally on the 2.4 GHz band, passing through walls and ceilings up to 20 m.

The system includes an automatic on/off function that responds to the amplifier's signal: the transmitter and receiver switch on when audio is present and switch off or enter standby when the signal stops. This preserves the subwoofer's own standby feature. Additional receivers can be connected to a single transmitter for multi-zone bass distribution.

Key Features

• Digital 2.4 GHz wireless transmission, GFSK modulation, up to 2 Mbps data rate
• Audio frequency range: 20 Hz–48 KHz
• Audio in/output: RCA, mono and stereo
• Transmission range: up to 100 m free field, up to 20 m through walls and ceilings
• Automatic pairing between transmitter and receiver
• Automatic on/off — the subwoofer's standby function continues to operate
• Multiple receivers per transmitter supported
• Supply: 100–240 VAC 50/60 Hz or 5 V via mini USB
• Works with any brand of active subwoofer

Product Benefits

• Placing the subwoofer freely optimises bass output: without a cable constraint, the ideal acoustic position (typically a corner or along a wall) can be selected without routing cables across the room floor
• Digital transmission at up to 2 Mbps with GFSK modulation delivers interference-free bass without the analogue noise floor of RF senders
• The automatic on/off circuit means neither the transmitter nor receiver needs a manual power switch — the system follows the amplifier
• The 20 Hz–48 KHz frequency range ensures that even the lowest subwoofer frequencies are transmitted without bandwidth restriction
• Universal 100–240 VAC supply covers all international mains voltages with no adapter change needed

Why You'll Love It

• The kit includes both mono and stereo converter cables (2× mono and 2× stereo mini jack female to coaxial), covering both LFE mono and stereo line-level subwoofer inputs without any additional adapter purchase
• All cables and power adapters are in the box — transmitter, receiver, 2× mini USB cables, 2× USB power adapters, and instruction manual — so setup is immediate on delivery
• Red and green LED status indicators on both units provide clear visual confirmation of power and link state during installation
• The subwoofer can be re-positioned at any time without modifying the amplifier connection — the transmitter stays at the amplifier and only the receiver moves with the subwoofer
