audioXpress September 2021 Takes Speaker Building to the Next Level

audioXpress September 2021 celebrates its Speaker Builder magazine origins, once again offering an expanded focus on loudspeaker building, design, and testing. Mike Klasco provides an update on Speaker Technology, Claus Futtrup and Jeff Candy discuss Parameter Estimation and Box Simulation with Speakerbench, and Geoff Hill tells us the Tetrahedral Test Chamber Story. In this edition we pay tribute to Roger Russell (1935-2021) and we feature two great DIY projects. Now available online and in print.

For this last edition of 2018, audioXpress compiled a Voice Market Update that explores some of the latest developments and platforms for voice processing, with contributed articles from world-renowned experts in voice. The December 2018 edition reviews the ZOTL Ultralinear Power Amplifier from Linear Tube Audio; explains how to explore Soviet Germanium Transistors; and measures new SMT Low-Voltage JFETs. This is an edition you don't want to miss.

In this edition, audioXpress pays tribute to one of its most esteemed and prolific writers, Ron Tipton (1936–2018). In our cover feature, Scott Dorsey details his fascinating visit to the Library of Congress National Audio-Visual Conservation Center. Tom Perazella concludes the construction of his flagship Egg Speakers, Andy Lewis explains more about Back EMF, Peter Lehmann shares his time-alignment design for a two-way speaker, and Ethan Winer shares his experience with the affordable LabNation SmartScope USB oscilloscope. And that's just the start of another great edition, now available in print and online.
