Monitor Audio Radius On-Wall 4G Speaker

78mm deep, and it comes with its own bracket

The Monitor Audio Radius On-Wall 4G is a slimline two way with twin 4.5 inch RST III bass-mid drivers either side of a 25mm C-CAM Gold Dome tweeter, in a cabinet just 78mm deep. It is sold as a single speaker, so a left and right pair means ordering two, and a three channel front stage means three. A wall bracket and fixing template are supplied in the box.

Why You'll Love It

• Nothing extra to buy. The wall bracket and a fixing template are included, so the speaker arrives ready to mount rather than needing a separate accessory order.
• Loud where it counts. 90dB installed sensitivity and 114dB maximum peak SPL make this the most efficient speaker in the Radius 4G range, which is what you want either side of a television.
• Barely there on the wall. At 78mm deep it sits close enough to the plaster to live beside a wall mounted screen without looking like an afterthought.

Under the Hood

• Two way design with 2 x 4.5 inch RST III bass-mid drivers and a 25mm C-CAM Gold Dome tweeter, crossing over at 2.3kHz.
• Ported cabinet tuned to 62Hz, with through-bolt driver bracing and the new Radius 4G crossover design.
• In-room response from 69Hz to 35kHz at -6dB, 114dB maximum peak SPL to AES75, and 100W continuous power handling to CTA 426-B.

CHT Insider Verdict

The two things to get right here are quantity and crossover. It is sold one at a time, so price a full front stage accordingly, and it rolls off at 69Hz in room, so it is a subwoofer partner rather than a full range speaker. Given that, it is a strong on-wall option, and the included bracket saves both money and the usual guessing about what hardware fits.

Pro Tip: Mount it vertically for left and right, and only lay it horizontally for a centre channel if you have no alternative. A horizontal driver-tweeter-driver layout narrows the sweet spot horizontally, which is the opposite of what you want for the seats at either end of the sofa.
