Planar Ribbon Loudspeaker
THE RADIA SERIES planar technology
520i
With a wonderfully natural sound, and a slender shape that makes it one
of the most versatile loudspeakers available, the Radia Series 520i loudspeaker is something
to covet. The Radia 520i uses a 50-inch planar ribbon line-source driver with a linear
push-pull motor, which drives an ultra-light diaphragm above its passive crossover point of
350 Hz. Handling the lower frequencies is a pair of high-powered, long-throw mid-woofers.
Together, this innovative combination delivers the timing and dynamics to effortlessly
handle any source material from music to home theater.
Unlike many audiophile speakers, the Radia 520i offers excellent power handling,
accurately reproduces dynamic peaks and offers long-term reliability as well. Housed in
a custom, black-anodized aluminum tower with an MDF base, the Radia 520i is finished
in a striking wear-resistant coating, which means it’s a product that you will enjoy for
many years to come.
Dynamic. Smooth. Ultra clean. The 520i shatters the performance barrier that is inherent
with conventional high-performance loudspeakers.
›Flexible Exclusive line-source Radia planar technology produces a cylindrical sound
field, eliminating any unwanted mid and high-frequency floor and ceiling reflections.
›Dynamic Accurately reproduces dynamic peaks at high power for realistic reproduction.
›Lifelike Planar ribbon drivers provide amazing clarity, resolution and fidelity.
Critically acclaimed, the Radia 520i is a favorite among audiophiles and reviewers from
around the world.

The loudspeaker consists of an MDF enclosure, which houses the mid-bass
drivers and crossover components. An aluminum tower containing a modified
RD50 planar ribbon driver is attached to complete the speaker system.
Both the enclosure and base have a durable black coating. The planar driver
is finished with a black fabric grille and black anodized tower.
The crossover network divides frequencies between the mid-bass and planar
drivers at 350 Hz. The crossover is equipped for bi-wiring and is shipped with
removable shorting straps across the high and low frequency inputs.
The Radia 520i is easy to drive with any high-quality amplifier or receiver.
It also features ample power handling and can be used in large-sized rooms
for either music or home theater applications. Though the 520i can be used
full-range, a high-quality subwoofer, such as the Radia 210i, is strongly
recommended for optimum low-frequency extension as well as additional
power handling.
