Adastra Bluetooth Music System + 5.25" Slimline Ceiling Speakers (Pair)

by Adastra
£89.99 (inc. VAT)


This Adastra Bluetooth Music System comes complete with a pair of 5.25" slimline ceiling speakers and is a cost-effective audio solution that brings high-quality music to your kitchen, lounge or bedroom.

Playing music in your kitchen or lounge has never been easier; simply pair your smartphone or tablet to the Bluetooth amplifier and away you go! You can even pair your Amazon Alexa or Google Home and control the system with your voice 'Alexa play the radio'. Alternatively, you can plug a device straight into the Aux/TV input. 

Our Adastra Bluetooth Music System is quick and easy to install and has you streaming all of your favourite music in no time. The supplied Bluetooth amplifier is extremely compact and can sit in a cupboard, in the wall or even above the ceiling.

The 5.25" slimline ceiling speakers feature a hi-flex polypropylene cone main driver for extended low frequency response, and a mylar tweeter unit for accurate HF reproduction. A flared wave-guide baffle helps to aid dispersion for wider coverage, and a precision 2-way filter network gives accurate high-low separation. The twist-fit grille enables quick and neat installation resulting in a premium quality sound delivery system.

Supplied with 20 metres of 2-core 2x24 speaker cable.
