From Paul Messenger
I need to report that my close association with Hi-Fi Choice magazine (covering some 30 of the past 34 years) was terminated following the magazine’s recent purchase by an organisation with the unlikely name of My Hobby Store (which also now owns Hi-Fi News).
Although the previous owners hadn’t seemed in the least concerned, the new management was unhappy that HIFICRITIC was promoted on the basis that its freedom from advertising ensured superior independence from commercial pressures. I was effectively given an ultimatum that if I wanted to continue to work for Choice, I would have to give up editing CRITIC.
Acoustics: Sound Fields and Transducers by Beranek and Mellow
ISBN-13: 9780123914217, Elsevier Science, 0/4/2012 720PP
I first encountered Leo Beranek’s book Acoustics while researching material for High Performance Loudspeakers which first edition was published in 1976/77, when Acoustics had been in print for some 20 years. Now, more than half a century later and encouraged by Tim Mellow, Beranek and Mellow have collaborated to produce a new edition of Acoustics, founded on the original classical fundamentals but with a modern slant more clearly focused on electroacoustics and carrying the sub-title, Sound Fields and Transducers.
Designed in the first half of 2011 by Martin Colloms, Christien Ellis (CE Electro-Acoustics, www.christienellis.co.uk) and Miles O’Carroll (firstname.lastname@example.org) The Rhythm King has passed its proving trials and is ready for demonstration at the National Audio Show September 24/25. Room S15 with ticketed presentations on the design principles involved.
Wilmslow Audio built the enclosure to drawings created by Miles O’Carroll from design sketches by Martin Colloms and Christien Ellis. Wilmslow Audio have agreed to supply all the parts required including the exclusive supply of the Cotswold Acoustics manufactured, BMR full range planar driver. The custom made Multi-Contact terminated solid core internal and external wiring harnesses are built by DNM Design and work with external, easily updated crossover networks.
This speaker is designed for wall boundary matching and a neutral timbre.
