Beolab 4000 speaker conversion with Wifi and Trueplay support

Enhance your vintage Beolab 4000 by turning it into a state-of-the-art Sonos player with our comprehensive upgrade kit. Experience significantly improved sound quality after upgrading, seamlessly integrating your speaker into your Sonos system.

Unlike other solutions that require separate Sonos components, this upgrade turns your Beolab 4000 into a fully integrated Wifi Sonos speaker. With dedicated play/pause and volume control buttons, along with Ethernet and a power outlet, your speaker becomes a fully integrated part of your Sonos setup.

Simply replace the outdated electronics in your existing speaker, preserving the essential woofers and tweeters. Install the new amplifier circuit board, power supply and keypad and refresh the old grommets with new ones supplied. It is important that the speaker is completely sealed for optimal sound.

After the hardware upgrade, you can fine-tune the speaker's performance by running Sonos Trueplay from your iOS or Android phone. This calibration ensures a straight frequency spectrum, optimizing the audio experience to its full potential.

The kit contains everything needed to convert a single speaker. If you're looking to upgrade a pair, buy two kits for a massive upgrade to both speakers.
