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.
