Radian Audio Engineering on Voice Coil Test Bench
For the February 2020 edition of Voice Coil magazine, Vance Dickason characterizes a new Radian ferrite compression driver.
The Test Bench focus on Radian's 835PB ferrite 1.4” aluminum diaphragm compression driver. After reviewing several of Radian’s neodymium series of compression drivers, Dickason characterized the 835PB and noted how this driver continues to have the expected rich feature set that is the hallmark of the company.
Renowned for its mastery of diaphragms, compression drivers and coaxial loudspeakers, with the 835PB, Radian Audio shows how the company continues to offer excellent performance in a fairly high power handling package (200 W continuous power handing). Features for the 835PB 3" diaphragm, 1.4" exit, compression driver includes a 3” polyimide voice coil former with a copper clad aluminum edge wound ribbon wire voice coil, a self-aligning field replaceable diaphragm assembly, and the most important feature, a proprietary processed and hardened aerospace-grade aluminum alloy diaphragm over a three slit phase plug. The 835BP is also available with a beryllium diaphragm.
