Test Bench: The Dayton Audio DMA58-4 2" Full-Range Speaker Driver

In this Test Bench, the focus is the Dayton Audio DMA58-4, a new 2" full-range line array/smart speaker from Dayton Audio. DMA stands for Dual Magnet Aluminum Cone and the series already includes five models of full-range drivers, all using a proprietary 12-spoke injection-molded frame. This frame is very open to reduce reflections back into the cone and also has a very generous mounting flange making multiple driver arrays cosmetically attractive and compact.

Test Bench: B&C Speakers DCX464 High Power Coaxial Compression Driver and Horn
by Vance Dickason

Test Bench: B&C Speakers DCX464 High Power Coaxial Compression Driver and Horn

The driver to be characterized in this Test Bench is from B&C Speakers and is the DCX464, a pretty unusual ring radiator compression driver. First, because it’s a coaxial compression driver - a rare category of compression driver, and second because the DCX464 compression driver and the accompanying horn measure down to an honest 300 Hz, which is quite a low frequency considering only a few OEM horns on the market go even as low as 400 Hz.
