Test Bench: Radian Audio Engineering 475PB 1-Inch Compression Driver

In this Test Bench I characterized the 475PB, a 1" compression driver from Radian Audio Engineering. The 475PB has a similar set of features as Radian’s 745PB. This includes a 1” throat diameter, a 134 mm × 19 mm ferrite magnet motor, and the most important feature—a proprietary processed and hardened aerospace-grade aluminum alloy diaphragm over a three-slit phase plug.

Test Bench: Radian Audio Engineering 745PB 1.4” Compression Driver

In this Test Bench I characterized the 745PB 1.4” compression driver from Radian Audio Engineering. Based in Orange, CA, Radian is a serious player in the OEM loudspeaker component business, the sound contractor/fixed installation market, and the portable/tour sound industry. The 745PB has the expected rich feature set of other Radian compression drivers. Subjectively, this speaker is incredibly musical, detailed, and extremely easy to listen to — certainly a goal for all monitors. This article was originally published in Voice Coil, December 2018.

Test Bench: Dayton Audio RS180P-8 7” Reference Series Midwoofer

The 7” RS180P-8 Reference Series midwoofer from Dayton Audio uses a nice six-spoke cast-aluminum frame with narrow 10-mm wide spokes to minimize reflections back into the cone. The cone assembly is composed of a three-part lightweight paper cone that combines Kevlar and glass fiber with the paper slurry. Cosmetically speaking, this is very good looking driver.
