Reference BlieSMa M74A-6

BlieSMa was founded and in Germany in 2018 by Stanislav Malikov who for a long time worked in such world famous companies which produce loudspeaker drivers as Morel (Israel) and Thiel&Partner (Germany, more familar in the world by its trademark - Accuton). The main activity is the development and production of high-quality loudspeaker drivers.

The tweeters come in pairs and come in two versions: aluminium and beryllium - one of the best material available to speaker drivers manufacturers today.

BlieSMa T34B-4 Beryllium Dome Tweeter

The BlieSMa T34B-4 1-1/2" Beryllium tweeter is the beryllium version of the T34A-4. Offering an even more linear frequency response and the benefit of a resonance peak that lies beyond the 30kHz. The large surface area combined with a Peak to Peak excursion of 3mm gives this tweeter the ability to be safely used down to 1300Hz.

BlieSMa T34A-4 Aluminium-Magnesium Dome Tweeter

The BlieSMa T34A-4 1-1/2" Aluminium-Magnesium tweeter belongs to the absolute best of this market. The extremely linear frequency response and its amazing wide dispersion are unmatched by any other tweeter. The large surface area combined with a Peak to Peak excursion of 3mm gives this tweeter the ability to be safely used down to 1300Hz.

BlieSMa T25B-6 Beryllium Tweeter

The BlieSMa T25B-6 is a 25mm beryllium dome with ultrasonic first breakup mode. Extremely low moving mass for better transient response and higher efficiency.

BlieSMa T25A-6 Aluminum Dome Tweeter

The BlieSMa T25A-6 features flexible and lightweight lead wires made in Denmark. Thick aluminium powder coated flange and an aluminium rear chamber with natural wool damping. Gold plated wire terminals. Recommended frequency range 2.2kHz-35kHz.
