Gold GX

November 2011

Setting the Gold Standard

Home Cinema Choice magazine gives their verdict on the Gold GX Series with an all round 5 star approval across the board.

In the latest January 2012 issue of Home Cinema Choice magazine our Gold GX series was reviewed, tried and tested for performance, design and features and then rewarded with a fantastic overall review of 5/5 stars across the categories.

Here's a snippet taken from the full review "Running through Pirates...had me scribbling all sorts of notes ('huge, rich, foundation-shifting bass with power and grip'; 'nil flex on the 15in piston'; 'Exciting, musical and able to create a sense of scale'), but all you need to know is that I loved this system with a passion."

I have just added GXW-15 Sub Woofer to my Monitor Gold system and the results are superb.I have other subs but the addition of this unit puts the icing on the cake. Select one of your favourite action DVD's turn up the wick and enjoy the base vibrations, superb, it's clean,deep and controlled. The quality of build, no cabinet extra vibration, is excellent. The manual is also well written and makes the speaker set up easy even for a novice.
