Burmester B28 Loudspeaker
In 2022, Burmester launched the B28 loudspeaker model to complement the B-Series. The design of the B-Series is characterized by clear lines, which are reflected in both the shape of the housing and the fronts.
Like the larger B38, the B28 loudspeaker works on a 3-way principle, but in the case of the B28 all the drivers are arranged on the front of the speaker. To work independently without interaction, each is located within its own housing chamber. Sonically, the B28 speaker also benefits from systematically integrated stiffening elements for structural stabilization and reducing cabinet vibrations. Unwanted resonance is subsequently successfully minimized, increasing the loudspeaker’s accuracy. To eliminate microphonic effects, which can have a negative influence on the frequency response, the crossover is also placed in a separate chamber. The two flow-optimized, high rigidity bass reflex tubes employ very smooth surfaces to enable the B28 to reproduce the lowest frequencies with a high level of accuracy. By means of the sophisticated, technically high-quality signal routing and the use of fine core Burmester cables, as well as large cross sections, detrimental transmission losses can be almost eliminated.
