The loudspeaker base is constructed of an MDF enclosure that houses the two long-throw cone drivers and the crossover components. This configuration allows for a claimed effective frequency range of 70 hertz to 20 kilohertz (–6 decibels, half space). The 520i, used as front left and right speakers, features a 50-inch-tall, planar magnetic line-source and two 6.5-inch cone drivers located in the base. Voilà! Sound.įor this review, I partnered the Radia system with a Samsung LCD monitor, an Onkyo DV-SP800 universal disc player, a Parasound Halo C 2 processor, Sunfire Cinema Seven Signature Edition and Simaudio Moon Aurora seven-channel amplifiers, and Kimber 8TC speaker wire. When the conductors are energized by an amplifier's signal, the membrane responds by moving in a push-pull fashion as the signal varies. The membrane is bonded with conductive traces and then suspended in a magnetic field. What distinguishes the planar ribbon driver from more-traditional speaker technologies is simply this: Most of the frequency range is generated not by a cone driver but by a flexible membrane. According to B-G, improvements include 'new advanced Linkwitz-Reilly crossovers for improved balance and reduced phase distortion and updated planar ribbon drive units for higher efficiency, lower distortion, and extended frequency response.' The individual speaker nomenclature has not changed from the earlier model, except for the addition of the letter 'i' (for 'improved') to each speaker designation. You may not be too familiar with the Bohlender-Graebener name but, when it comes to hybrid planar magnetic driver technology, the name isn't uttered without a good deal of respect.Ī couple of years after B-G was launched, HT reviewed an early iteration of the present review system. The Radia Series speaker system is the latest development from what can be considered a seriously thick branch in the speaker-manufacturing tree.
