Burmester BA 71
Absolutely breathtaking, the BA 7.1 have a meticulous reproduction of even the most subtly details in your music. Complemented by a mighty dynamics, warmth and substance in genuine Burmester Quality.
With the Ambience BA71 Dieter Burmester created a loudspeaker that combines striking sound with the highest musical fidelity and almost unlimited power reserves. 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.
The front of this elegant speaker is made of solid aluminum and available in silver, medium bronzed or black. The speaker enclosure made of solid wood is elaborately braced on the inside and available in these cabinet finishes: High-gloss makassar, high-gloss walnut in light or dark, high-gloss white or high-gloss black enamel. Of course, the finish of fronts and cabinets may be custom combined.
Drivers are carefully selected and subjected to a weeklong burn-in process before mounted in identical pairs to ensure perfect stereo sound. The hand-assembled frequency crossovers are carefully connected to the drivers, with individual crossovers for different frequency ranges to ensure optimal performance. They are expertly mounted as close as possible to the respective drivers.
- Four identical woofers for enormous power handling and dynamics, coupled with high sensitivity.
- Separate closed chamber for the low-mid chassis to save them from the low-frequent pressure waves and thus refine the mid-range.
- Air Motion Transformer (AMT) with feather-light diaphragm, super strong neodymium drive, outstanding wealth of details, sonic neutrality and continuous high level capability.
- Veneer and lacquer finishes in five different versions may be combined with aluminum fronts in three different colours.
