Parameter Estimation and Box Simulation with Speakerbench (Part 2) - Introducing Speakerbench

November 17, 2021 by Claus Futtrup and Jeff Candy

Parameter Estimation and Box Simulation with Speakerbench (Part 2) - Introducing Speakerbench

In the first part of this work, the authors discussed the difficulties in estimating cabinet losses using the classical Thiele-Small framework, and proposed a solution using an advanced transducer model. In this second article, the authors detail how their Speakerbench web-app offers an accurate and practical approach to this problem, and demonstrate how users will be able to easily and accurately determine the best suitable box volume for a loudspeaker system. This article was originally published in audioXpress, September 2021.

Parameter Estimation and Box Simulation with Speakerbench (Part 1) - Model Parameter Comparisons

The two authors investigate leakage loss as identified with an advanced transducer model and verified with measurements. This is compared to classical Thiele-Small modeling with the intention to motivate the reader to further explore advanced parameter estimation and box simulation with the Speakerbench Speaker Design Calculations online tool. This two-part article concludes with an overview of how Speakerbench offers an accurate and practical approach to this problem. This article was originally published in audioXpress, August 2021.

Audio Precision APx500 Flex Audio Analyzer — Hands-On

Vance Dickason writes about the Audio Precision APx500 Flex Audio Analyzer and shares his hands-on experience with this latest affordable analyzer solution, designed to work with third-party USB audio recording interfaces. Dan Knighten, AP's VP of Product Development, and Michael Martin, AP's Product Marketing Manager, brought a complete system to Dickason's place and assisted him in performing a series of R&D type measurements on the same driver featured in a Test Bench column. Which means, readers can compare the readings and results directly! This article was originally published in Voice Coil, March 2020.

Beyond Thiele/Small DUMAX and Klippel Driver Measurement Systems

March 13, 2019 by Thomas Perazella

Beyond Thiele/Small DUMAX and Klippel Driver Measurement Systems

Anyone who is serious about designing a loudspeaker using dynamic drivers is either familiar with, or has used, Thiele/Small parameters, generally accepted as ways to predict driver behavior in different enclosures. But there are other measurement methods we can use to determine and quantify nonlinearities: the DUMAX system, produced by DLC Design, and the Klippel Analyzer System by Klippel GmbH. This article was originally published in audioXpress, March 2003.
