Questions & Answers

Features we love

Tallboy and satellite speakers

The combination of tallboy and satellite speakers will immerse you in your favourite films and games. Tallboys stand tall on their own, without the need to be shelf or wall mounted, while satellites are smaller speakers placed around your room out of sight. By using both types, your system is able to recreate a wide range of audio experiences, from horror movie monsters creeping up behind you to the thunderous roar of a waterfall in a nature documentary.

Powerful Surround Sound

With a huge 1000 Watts of power, this system is ideal if you love to immerse yourself in a movie. It can create more than enough volume to fill your whole house with sound, so it’s perfect for living every moment of the action, or all the thrills of the match. This model’s impressive wattage means you’ll never lose sound clarity, so film scores will always sound cinematic.

High res Audio

High resolution audio is like high definition TV for your ears. With this system, you can enjoy crisp, clear sound that’s well rounded and natural. The ability to hear clear dialogue, epic music and subtle background noises will truly enhance your movie nights. You’ll be able to enjoy everything in the way it was supposed to be heard, with deep bass and sharp high notes, for the best quality experience.

Connect via Bluetooth

Free yourself from annoying wires and stream your music wirelessly via Bluetooth. Simply connect using your smartphone or tablet. Instantly access your own music library or sign into streaming services to search for the perfect party playlist. At the touch of a button, you can fill the room with your favourite tracks, completely wirelessly.

optic cable and setup

had to buy optic cable as not supplied to make sky box work on surround sound and instruction to setup was not clear difficult to understand

Works well

Easy to set up and works very well. The Bluetooth function is good with the LG tv I also bought. Sound quality is good and gives you that cinema feeling when watching a film.

All will not work

Bought it to go on a Samsung 3d tv but it says on some parts ,only available on a LG tv , I was told it was fully compatabal with my tv , I am still thinking about getting in touch with them ?

Ace sound

We were very pleased with these items and the sound quality is awesome and the delivery service was awesome too very quick and very friendly


Expected better from LG. Cannot get decent sound from LG TV despite using optical cable. Same with HDMI connection. Time lag with Bluetooth connection. Only thing that works well is the Woofer. My old Panasonic performed better with clearer sound. And yes. I have set it up properly.


Great value for money, doesn’t take up too much space and looks great
