With the latest addition to the expanding Radius family, Monitor Audio demonstrates once again that you don’t need large, intrusive loudspeakers to bring true hi-fi performance to music and film. By any standards, the Radius 720 subwoofer is a remarkable design, which proves that diminutive dimensions and dynamite performance are not mutually exclusive.
An evolution of the super-compact R360 subwoofer, it possesses the speed, subtlety and accuracy to enhance the highest quality music reproduction but delivers the power and slam demanded by movie soundtracks with an ease and authority unprecedented for its size. The R720’s twin downward-firing 8" treated paper cone drivers are mounted within a ported enclosure and controlled by a powerful built-in 250 watt amplifier. Its versatile control settings make it the perfect partner for all Radius loudspeakers and ensure compatibility with most other speaker packages. Crossover control range is 40Hz -180Hz.
Speaker level connections achieve optimum performance in a stereo audio system or in the absence of RCA outputs on the amplifier. RCA stereo inputs and an LFE input are provided for connection to a two-channel amplifier or multi-channel home cinema receiver. An auto function switches the R720 on when an input signal is detected. And switches it off after approximately 15 minutes if no input signal is detected. As with all Radius products, build quality and finish are of the highest order. The R720’s cabinet is constructed from heavy duty MDF throughout, lending a weight and solidity that belie its svelte dimensions. The real wood veneer, satin and lacquer finishes, aluminium back plate and smooth-acting, rubberised controls are all part of the quality-led approach that sets Radius apart.

A new type of port technology which uses a straight rifled design to accelerate air flow and reduce turbulence. HiVe II technology has the ability to move air in and out much quicker than a conventional port, the result is fast powerful bass coupled with superior transient response.

Radius R270
“It’s hard to imagine a more elegantly styled speaker system than this one from Monitor Audio. The performance is superb, highlighted by razor-sharp precision, with the sub easily able to keep up with the rest of the system and deliver the necessary muscle."

'The Radius range just keeps on giving...it doesn't impose itself like many large systems...sonically, the system is massively impressive...open, detailed and dynamic; composed and coherent even when pushed...it should be seen and heard!'There are currently no user reviews for this product.
