Burmester BA31





The cabinet front is made from solid, acoustically decoupled aluminum finished in silver, medium bronzed or black. The speaker housing, elaborately braced on the inside for stiffness, is available in high-gloss finished makassar or walnut light and walnut dark. Alternatively, the speaker is also available in white or black high-gloss enamel. Of course, a combination of finishes for fronts and cabinets may be custom selected.


In Burmester’s specialized Berlin speaker factory the hand-assembled frequency crossovers are carefully connected to the drivers, with individual crossovers dedicated to different frequency ranges to ensure optimal performance. They are expertly mounted as close as possible to the respective drivers.
