LoudSoft Updates FINECone 2020 Simulation Software

The new release of LoudSoft's FINECone 2020 software is a welcome and important update for the loudspeaker industry. LoudSoft seems to have listened to its customers and added a new Geometry Modeler, which makes simulating cone frequency response much easier for engineers using FINECone. FINECone is an acoustic Finite Element dome/cone simulation application to assist on the design of new drivers, calculating frequency responses and detecting problems in existing designs.

This article discusses an approach for time-efficient testing of loudspeaker suspension parts, close to their final operating conditions. It refers to the Linear Suspension Test set (LST Lite), a hardware and software add-on for the Klippel QC loudspeaker end-of-line testing system. The system may be applied to 100% of the parts or to a random sample. This article was originally published in Voice Coil, December 2012 (with some updates introduced from 2019 documents).

This month I tested one of Volt Loudspeakers' signature products, the 3” VM752 midrange dome. The VM752’s features include a coated single-piece fabric dome/surround, a FEA-designed ferrite motor structure, and a 75 mm diameter Nomex/Kapton voice coil former wound with round copper wire. A short flare horn is built into the rear-mounted (0.75” depth) faceplate. The VM752 also offers 94 dB sensitivity, and 100 W (AES) rated power handling, has a 200 mm diameter ferrite magnet, with a 2 mm Xmax, and a 500-Hz-to-4-kHz operating range.

Voice Coil August 2017 is now available. Read an excellent tutorial from Charlie Hughes about optimizing loudspeaker directivity through the crossover region, and read James Croft’s review of a new bass-reflex speaker cabinet design. In Test Bench, we learn more about are Tymphany's new DFM-2535R00-08 compression driver and Volt Loudspeakers' new VM527 dome midrange.
