Test Bench: A New Beryllium Tweeter from BlieSMa

This Test Bench characterizes the T34B-4 34mm beryllium dome tweeter from BlieSMa, a German company founded in 2018 by Stas Malikov. BlieSMa’s first tweeter offering, the T34A-4 34 mm aluminum/magnesium alloy dome, appeared in Voice Coil’s June 2018 Test Bench. This month, I received the company’s second offering, and it seems logical that this driver, the T34B-4, is a 34 mm beryllium dome tweeter. This article was published in Voice Coil, March 2019.

BlieSMa, located in Blieskastel, Germany, was founded January 16, 2018 by Stas Malikov. Prior to starting BlieSMa, Malikov worked at Ultrasound Technologies, at Morel as a QC manager and a transducer engineer, and at Accuton as a production engineer for the last 8 years. The first product released by BlieSMa is the T34A, a 34 mm tweeter. Available since May 2018, the T34A is a metal aluminum/magnesium alloy dome tweeter.
