CODA Audio Launches HOPS10-Pro Advanced Triaxial Professional Loudspeaker

The new HOPS10-Pro from CODA Audio is a high output 3-way point source loudspeaker with an advanced design, featuring dual 10” neodymium low distortion woofers to provide power and accuracy across low frequencies, combined with a 1.4" coaxial neodymium midrange and high-frequency ring-diaphragm driver. The design alignment ensures a perfectly coherent and uniform wavefront, resulting in a full-range sound reinforcement solution with a powerful 1400W rating, in a compact enclosure.

Capable of 135dB peak SPL, Martin Audio’s latest announcement, THS, is an extremely powerful point source loudspeaker which combines very high output with extended frequency response. This new design using a custom version of the DCX464 Coaxial HF dual-diaphragm compression driver and a 15" woofer, joins the wider TH series from the British manufacturer, and is ideally suited to medium-scale DJ club applications and installations which call for exceptionally high sound levels from a compact, standalone loudspeaker system.

In this issue. Mike Klasco looks at the exciting progress happening in magnets and new signal processing options for speaker design. James Croft compares patents of ducted loudspeaker designs for automotive. And for Test Bench, Vance Dickason characterizes the new Russo 44CDN-PK 1" PEEK diaphragm compression driver from SB Audience, and the B&C Speakers DCX354 ring radiator coaxial dual-diaphragm compression driver.

Modern speaker arrays demand closer source spacing, higher output, and lighter weight. To meet this continuing challenge, Italian manufacturer B&C Speakers introduced the new DCX354 coaxial ring radiator. A more compact sibling of the groundbreaking DCX464 launched in 2019, the DCX354 comprises five years of R&D, two patents, and a radical MF diaphragm design to achieve what the company describes as its loudest, widest-bandwidth compression driver yet.

In the wake of innovation breakthroughs made possible by wide-bandwidth ring radiator drivers, B&C Speakers has now released the ME464 1.4-inch horn built especially to extract the full potential of the DCX family of coaxial drivers. The largest horn so far introduced by the Italian company and commercially available, the ME464 horn offers 70° x 55° nominal coverage with constant directivity and excellent loading down to 300 Hz. The development follows the introduction of the B&C DCM414 midrange compression driver, building on the DNA of the DCX464 HF coaxial design.

The October 2019 edition of Voice Coil is packed full of essential reading material. Vance Dickason discusses Zero Phase in Studio Monitors with commentary from industry experts. In Acoustic Patents, a new Speaker Structure design patented by Yamaha, and a new Passive Acoustic Radiator Module, invented by Joseph Sahyoun are under review. And Test Bench characterizes a new high power coaxial compression driver and horn from B&C Speakers, and a 28 mm silk dome tweeter from Trueanalog. Now available to download!

B&C Speakers' engineers have been working for the last five years on a family of next generation high frequency devices. The result is the DCX464, a new time coherent coaxial ring radiator design with a neodymium magnet assembly, which the company believes will open new horizons for the professional audio industry. The 1.4” horn throat diameter of the DCX464 delivers a complete response from 300 to 18000 Hz thanks to a patent pending design that combines both diaphragms. VC
