Our Gold series has received further acclaim, this time from seasoned industry reviewer Danny Phillips. The Gold 200AV 5.1 system has left a lasting impression for its balance of powerful yet detailed sound, earning a Trusted Reviews Recommended badge!

"Beautifully designed" Gold 300 & W15 Subwoofer

A full five stars for our Gold 300 floorstanding speaker and Gold W15 subwoofer!

Reviewer Bob Barrett tests the 2.1 Gold series setup with an array of music and film; putting it to the test and experiencing what the series has to offer:

"the soundstage was very wide, again compliments of the ribbon transducer. And the Gold 300 speakers reproduced it all with the tonal neutrality found among only the best loudspeakers."

"The W15 provided an excellent deep-bass foundation, adding to the scale and impact of this selection."

"The beautifully designed Monitor Audio Gold Series system is the best-sounding surround system at its price point that I’ve ever heard, period."

Gold 5.1 is a stunner!

October’s edition of Home Cinema Choice hosts a stunning review debut for the Gold 300AV 5.1 system. Awarding a Best Buy (rare at the price level) and five glorious stars in every category: Performance, Design, Features and Overall, the magazine’s home theatre doyen Adam Rayner concludes “So, the Gold 300AV costs plenty but offers enormity. It has the might and it has clarity. It can play sweet and linear at low levels or it can frighten the neighbours’ neighbours. The sheer bandwidth on tap is amazing and in truth, after admiring the design and finish and a little experimentation with the sub’s EQ settings, you’ll rapidly forget about the enclosures. The sound is immediately engaging, grasping you by the senses and dragging you into a movie with ease. With the Gold 300AV you get delicious performance in every direction. You could pay more and get less. Best buy, easy.”
