Loudsoft FINE Suspension Nonlinear FEA Spider and Surround Design Program

An overview of Loudsoft's latest FINE Suspension Nonlinear FEA Spider and Surround Design software. This new transducer engineering tool, specific to the development of speaker surrounds and spiders (dampers), allows for the simulation of different types of surrounds and spiders from imported DFX files or created from templates with parameters selected by the user, and then outputs the compliance curves similar to the Kms and Cms curves measured by Klippel DA2 or KA3 analyzers.

Test Bench: The AMT200P Pro Sound AMT and XMT200 Horn from Eighteen Sound

Test Bench: The AMT200P Pro Sound AMT and XMT200 Horn from Eighteen Sound

This Test Bench article characterizes Eighteen Sound’s AMT200P Air Motion Transformer and accompanying XMT200 6.5” waveguide. This driver is the brand's latest entry into the high-frequency transducer category, specifically designed for the pro sound community. The Eighteen Sound AMT200P includes a rectangular throat with a Kapton diaphragm with a neodymium magnet structure, and is rated for a power handling of 90W AES above 1.2kHz, with a sensitivity of 105dB, and a recommended crossover frequency of 1.2kHz at 48dB/octave. While the AMT200P can be used as a standard planar device it can be also coupled with a dedicated constant directivity horn, the 90°x 20° XMT200, featured in the characterization.

Test Bench: The 15DS100 15” Pro Sound Subwoofer from B&C Speakers

This Test Bench explication characterizes the 15DS100 15” professional subwoofer from B&C Speakers. This new transducer from the Italian company is a very high power handling design, able to deliver 3kW continuous (1.6W nominal), thanks to B&C's latest generation of very long voice coils - a great asset in applications from discreet PA subwoofers to three-way PA speakers. The B&C 15DS100-4 uses a proprietary 12-spoke cast aluminum frame with cooling vents for the neodymium FEA motor, which uses a 4” four-layer voice coil wound with round aluminum wire on a non-conducting glass fiber former.

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.
