This AV Link & Adastra BH Series on wall spekaer bundle is an excellent way to add music to your garden.

Make the most of the British summer by relaxing on the sun lounger with some tunes in the background and impress your friends at your one of your famous BBQ's with high quality sound, let them pair their phones and play a game of Spotify Roulette whilst the kids dance around.

Ditch the tiny portable speaker that keeps running out of battery and upgrade to this wired system that's always ready to play your music.

Simply connect your smart phone or tablet and the amplifier will turn on and begin playing. You can even connect other audio sources such as an outdoor TV, perfect for summer movies in the garden and sporting events!

Important, please note that the amplifier itself is not weather resistant and must be installed in a dry safe environment such as indoors or in a watertight garage/shed.
