At SB we believe in the importance of subjective listening during the development process to complement the advanced FEM stimulation, motor optimization, diaphragm design, voice coil technology, adhesives etc. We have done extensive listening and also compared to several high priced competing transducers, and at SB Audience we are really excited about the sound of these new drivers.

The new line of products incorporate a heavy duty distinctive looking cast aluminium rear chamber that visually define the new products. The chamber has been optimized to minimize resonances and absorb reflections.

• Exremely light weight PEI diaphragm
• Smooth response with airy detailed highs
• High sensitivity and compact design

With well over 35 years of experience in professional sound reinforcement drivers, we strive to bring this know-how to the world with the most competitive high quality drivers on the market. 

SB Audience is spawned from the heavyweight manufacturing of Sinar Baja Electric Indonesia and has serviced well known brands in the PRO audio industry for decades with in house engineering and manufacturing. There are three categories within our standard product range: Bianco, achieves good performance at the most reasonable cost. Rosso, aims at high performance at an attractive price, and Nero is our higher performance line still achieving exceptional price performance ratio.
