Test Bench: Three New High-End 25mm High-Frequency Transducers from BlieSMa

This Test Bench combines three new 25mm high-frequency transducers from German brand BlieSMa into a single characterization: the BlieSMa T25S-6 Silk Dome, the BlieSMa T25B-6 Beryllium Dome, and the BlieSMa T25D-6 Diamond Dome. All three tweeters appear to be built on the same platform, but optimized for each diaphragm material, and all three share pretty much the same feature set. BlieSMa was founded in January 16, 2018 by former Morel and Accuton engineer, Stanislav Malikov. This article was originally published in Voice Coil, September 2021.

In Voice Coil September 2021, Vance Dickason writes about DSP crossovers from Danville Signal, Joe Hayes (Vastigo) writes about the DaS AuReality patented 3D loudspeaker technology, and Mike Klasco finds speaker-related technologies that help support smart speaker design efforts. This edition's Test Bench characterizes three new 25mm high-frequency tweeters from BlieSMa, using silk, beryllium, and diamond domes: BlieSMa’s T25S-6, T25B-6, and T25D-6.
