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.

Launching at Cinema-Con 2019 (April 1-4) in Las Vegas, Danley Sound Lab's new range of cinema speakers combine the unique technologies and designs that have made the brand founded by Tom Danley. Loudspeakers featuring Danley’s Synergy Horn, full range, point source designs, and Tapped Horn subwoofers, combine to create a complete solution for cinema, including a dedicated surround speaker that is a fully horn-loaded, two-way coaxial design, and all powered by the company's range of DSP amplifiers with dedicated presets.

Fulcrum Acoustic is recognized by the industry for its unique approach to loudspeaker design. The company continues to expand that approach with its latest FH15 Full-Range Coaxial Horn product line. The FH15 Series features 2-way, coaxial horn systems with a 15” horn-loaded woofer and a 4” diaphragm compression driver to provide precise pattern control to below 400 Hz, low frequency extension to 54 Hz, and extremely high output for products of their size while using only a single amplifier channel.
