Burmester BA71 Reference Floorstanding Speaker

Speakers priced as a pair.

Its fundamental bass power despite its lean and elegant appearance is due to the separation of the bass diaphragm into four identical, compact bass drivers, which are energetically supported in the lowest registers by a bass reflex port. Two low-to-mid range drivers in a sealed compartment for each speaker provide well-balanced, tonally correct sound up to the treble register for which a new Air Motion Transformer (AMT) tweeter has been custom developed. However, what really sets this speaker apart is its adaptability to different rooms and listening tastes. An additional, rear-firing ambience tweeter can be infinitely adjusted to adapt the sound to individual tastes or listening room acoustics. It opens up the width and depth of the soundstage in a way that heretofore seemed possible only with omnidirectional or dipole speakers. However, with Burmester’s Ambience loudspeakers this phenomenon is not only achievable but also adjustable.

Design
The front of the elegant speaker is made of solid aluminum in the colors silver, medium bronze or black. The interior of the elaborately stiffened corpus made of sturdy wood is optionally available with surfaces in macassar high gloss, walnut high gloss in a light and a dark variant, high gloss white or high gloss black. The fronts and housing surfaces can of course be individually combined with one another.

Handmade
Before installation, each of the loudspeaker chassis is recorded in a one-week process, measured and supplemented with the corresponding counterpart for perfect stereo sound. The hand-assembled crossovers are connected to the loudspeaker chassis in the high-end manufacturer’s loudspeaker manufacture. In order to achieve the best possible performance in your respective task area, a separate crossover has been designed for each frequency range. These are expertly installed as close as possible to the respective chassis.
