The K2 Audio Bluetooth Express is an innovative garden speaker solution for discrete background music, all year round.

Simply install the external amplifier enclosure near your listening area, wire to the speakers and connect to power (in a dry safe place!) and your system is up and running.


Bluetooth Streaming: Simply connect your smartphone, tablet or computer wirelessly with Bluetooth and stream your favourite music from internet music apps, internet radio and much more.

Powerful: At 20W per channel of Class D digital amplification this little amplifier packs a punch and is suitable for moderate music listening on your patio. You’ll be surprised at the sound output this system can produce.

Always Ready: The K2 Audio amplifier stays in an ultra low power standby mode and simply wakes up when you connect your device via Bluetooth. No buttons to press, just connect and stream.

Stereo / Mono: You can set this amplifier as stereo for a true left and right soundstage, or set it to mono to allow for better speaker positioning in your garden. Often outdoor music can benefit from mono sound allowing you greater coverage and flexibility.

Water Resistant: The amplifier is housed in a water resistant external socket enclosure that can be wall mounted near the listening area, all year round. The speakers are also designed for outdoor use so can be mounted in your garden year-round.

Works With Alexa: You can also connect an Amazon Echo device to the amplifier via Bluetooth (Echo sold separately) to enable voice control of your speaker system.

This is sold as a complete kit including the amplifier, enclosure, speakers, speaker cable and power supply. As it’s an installed solution you may need additional items such as cable management.

The amplifier can be sited outside however the power supply is not waterproof and must be installed indoors, or in a suitably rated outdoor power enclosure.
