Mellow Acoustics FrontRo Pro Electrostatic Speaker

The Mellow Acoustics FrontRo Pro electrostatic speaker is a compact hybrid design that is hand-built in England. The FrontRo Pro electrostatic is comprises of locally sourced materials and joinery, and embodies fresh design theory. After years of research and refinement, FrontRo Pro uses the Oscillating sphere concept to radiate sound as uniformly as possible in all directions, like dropping a pebble in a pond. It immerses you in reflected sound as well as direct sound and thus creates a holographic sound image – unique amongst high-end speakers for the true audiophile.

The latest version features a new dynamic woofer with a powerful rare earth magnet for extended bass and an improved delay line for extra sparkle in the extreme treble. For more information, visit news page or download our product brochure here.

Oscillating Sphere concept

The electrodes of the Mellow Acoustics FrontRo Pro electrostatic speaker are divided into concentric rings, which are fed from a delay line. Hence, the sound emanates from the centre first and then from each successive ring until it leaves the outermost ring, by which time the sound from the centre is already some distance from the diaphragm. This produces a hemispherical wave front which spreads out in all directions.

Reviews:

Janine Elliot, Hifi Pig:

“…a highly 3D performance with pin-sharp top end and extended bass. The FrontRo was simply excellent in portraying the composer’s thoughts, working well at low level as well as loud. Birds and sea waves were equally real that my cat even pricked its ears to go hunting for game.”

Paul Messenger, Hi-Fi+:

“This is a loudspeaker with a distinct focus on sound that simply does the business, supplying good sound quality wherever one sits and
outstanding quality if you listen in the sweet spot.”

Jess Marshall, Luxury Lifestyle Magazine:

“FrontRo speakers are, an investment in music, an investment in entertainment, and an investment in interior design. For music lovers everywhere speakers don’t get much better, or more stylish than this.”
