Predictive Acoustics and Acoustical Modeling Software: ODEON Room Acoustics Software

This fifth article in the series explores the ODEON Room Acoustics Software, from the Danish company with the same name. Richard Honeycutt looks at the improved calculation methods and analysis capabilities of the sofware, incorporating an impulse response measurement system integrated to the software allowing easy comparison of calculated and measured responses.

This edition of Test Bench characterizes the 12FCX76, 12” high-performance pro sound coaxial from B&C Speakers. This coaxial driver is similar to the 12FHX76, where the “H” designates that it uses a horn-loaded compression driver, while the “C” in the 12FCX76 stands for conical-loaded compression driver (the “F” is for ferrite). The 12FCX76 uses ferrite motors for both the woofer and the compression driver. In terms of features, the 12FCX76 woofer is built on a 12-spoke (six twin-leg spokes) cast aluminum frame with eight mounting holes. This article was originally published in Voice Coil, July 2014.

The 1" diameter full-range drivers are among the most used transducers in consumer electronics. They are finding broad use in numerous Bluetooth speakers. The driver submitted by Tymphany for this Test Bench fits into that category. The Peerless by Tymphany PMT-40N25AL01-04 is a 25-mm (1”) diameter full-range driver built on a proprietary injection-molded two-piece polycarbonate (one piece for the motor assembly structure and one piece for the protective grill).
