An Interview with Patrick Turnmire

This interview was published in Voice Coil August 2013. Nearly 10 years since Patrick Turnmire, of Redrock Acoustics, had started providing Voice Coil with valuable Klippel data for Vance Dickason’s the Test Bench column. In this interview Patrick Turnmire explains his work with his company, Redrock Acoustics.

Speaker Design — The Cooks and the Wizards

Speaker Design — The Cooks and the Wizards

Some speaker designers approach their creations based purely on self-acquired knowledge and research, deliberately trying to distance themselves from existing trends and debates. Others, base their work on team efforts, industry partnerships, and sometimes market-oriented options. These are the people who I’ve started to categorize as the Wizards and the Cooks.

Diffraction Doesn’t Have to Be a Problem

This article shows an easy way to control baffle diffraction using a stepped baffle example. The author experiments with the use of felt, directly applied to the baffle and measures the results. Each piece of felt and its placement has different results. The article clearly demonstrates the diffraction effect on speakers and the benefits of having it under control.

Actran’s Acoustic and Vibration Simulation Software

The kind of acoustic simulation tools that were once the exclusive province of automotive and aerospace engineers are now available to loudspeaker designers. A speaker designer working in a home studio can design a new enclosure or ported box using the same simulation technology automotive engineers use to design quiet auto interiors or, more precisely, almost the same simulation technology.

Technology Stories We Should Mention: From Innovation to Market

Technology Stories We Should Mention: From Innovation to Market

The marketing breakthrough for a new technology is not just about successfully launching another disruptive product. In audio, or any other industry, innovation needs to be supported with clear go-to-market strategies. Sometimes unexpected engineering issues don't work in tandem with the marketing plan after the big product reveal - but really bad is to lose the momentum after all the awards and positive press.

Yorba Acoustics to Launch Unique Guitar Speaker Model G1 at NAMM 2015

Yorba Acoustics (YA) from Riverside, California, will be introducing the new Model G1 Guitar Speaker at the 2015 NAMM Show. The G1 uses a new patent pending reflector technology with a unique geometrical device for correcting the frequency response of the two opposing drivers as well as improving dispersion for better on and off-axis listening positions. As YA says, “The Astonishing Look Is Where Form Follows Function”.

$Acoustic Diffraction: Does It Matter?$

January 14, 2015 by James Moriyasu

Acoustic Diffraction: Does It Matter?

An excellent article from the audioXpress archive, published originally in February 2003, James Moriyasu offers a complete study examining speaker cabinet edge diffraction and what we can do to reduce it. The author attempts to measure the extent of acoustic edge diffraction and test possible solutions for reducing its levels
