Speaker Quality

The K2 Audio Bluetooth amplifier and ceiling speaker system allows you to add discreet in ceiling speakers to your room without bulky amplifiers and cables on show.

Don't be fooled by it's compact size, this is a highly capable system that's always ready to play your music.


  • BLUETOOTH: Connect your smartphone, tablet or computer wirelessly using Bluetooth and stream a world of music, movies and any app from your device.

  • AUX INPUT: There is a rear mounted 3.5mm audio input allowing you to connect local audio devices or TV's. The amplifier automatically turns on and plays once you turn on the TV or audio device.

  • POWERFUL: Despite it's compact size, this amplifier has a high quality UK made 22W class D digital amplifier and has four separate outputs to run up to four in ceiling, wall or outdoor speakers.

  • EASY TO INSTALL: This amplifier simply fits into a standard two gang electrical back box. It can be flush mounted or surface and as it doesn't have any buttons to press you can hide it in a kitchen cupboard or in the loft.

  • SMART SPEAKER COMPATIBLE: You can easily pair this to an Amazon Echo or a Google Home device for hands free voice control of your music and content. The speaker remains connected at all times, always ready to use.

  • CUSTOM NAMING: Through a simple to use web browser you can easily adjust the Bluetooth name (ideal if you have more than one in your home, one can be called "Kitchen" and so on...) you can set a PIN code for secure connections and also adjust the bass, mid and treble.

  • MONO MODE: You can also set this to mono output. Perfect if you just want one speaker in a room or if you're putting up to four outdoor speakers around your garden where stereo pairing isn't possible.



Upgrade Your Ceiling Speakers To High Definition


The standard speakers included with the Systemline E50 are the Q Acoustics Install QI65CB.

At 6.5" these are capable background music ceiling speakers designed to offer great sound quality at a low cost.

These are ideal for general background music, podcasts etc.


If you're looking for better sound quality then we'd suggest upgrading to the high definition QI65C speakers.

These are a night and day difference to the QI65CB, featuring a polypropylene cone instead of cardboard and a separate tweeter for high frequencies and built in electronics crossovers.

In English that means you get more bass and a much clearer, crisper sound quality.

The high def speakers are perfect where sound quality is important as they really do sound significantly better without costing a fortune.
