Burmester BC150 Reference Floorstanding Speaker

The BC150 features a specially developed damping system. For this purpose, the complex cabinet is coated with a 4mm thick steel plate and a special plastic. This dampens even the smallest vibrations.
Inside the speaker, stiffeners made of aluminum tubes are employed. These stabilize and solidify the integrity of the cabinet, so that the bass drive unit movement is converted to musical information alone. All drivers are braced against the cabinet with high preload forces to achieve optimum power transfer and create secure, long term coupling.

The BC150’s two Air-Motion-Transformer (AMT) tweeters in the design contribute significantly to the precision and detail that are distinctive characteristics of Burmester products. The front-located AMT drive unit is derived from the one used in the flagship BC350 and tailored for use in the BC150. Due to the lightweight, large-area foil membrane, which is located in a very powerful magnetic field, the high-frequency reproduction achieves optimum detail and transparency in combination with musical fluidity. The second AMT, located to the rear of the cabinet is adjustable to tailor the spatial depth of the sound stage according to personal preference. 

The midrange speaker of the BC150 uses, oval-shaped voice coil, which significantly increases the dimensional stability of the lightweight membrane. Thus, the BC150 is able to deliver excellent detail and tonally neutral music reproduction. By means of the very powerful magnet and the associated excellent mass-drive ratio, the sound image of the BC150 also achieves an impressively high degree of agility and resolution.

The large, side-firing woofer provides an exceptionally powerful, deep yet crisp bass. Again, this unit is also derived from the bass driver used in the flagship BC350 and optimally adapted to the conditions of the BC150. Its long-stroke diaphragm coupled with the powerful drive ensures powerful and immediate bass reproduction with sufficient headroom. The very lowest frequencies are delivered via the flow-optimized, carbon fiber bass reflex port with a very high degree of accuracy.
