The high-frequency reproduction benefits from the ring radiator developed exclusively for Burmester, which ensures optimum transparency and resolution. Low-mid and mid-woofer are an advanced development based on an already proven drive unit, which also aids the B18 to achieve an impressive sound performance.
The highly complex crossover is in its own enclosure chamber, as is the mid-bass driver, whose own closed enclosure results in particularly clean midrange performance.
The B18’s sandwich-constructed base is made of a high-molecular-weight thermoplastic polymer in combination with other materials of high internal damping and rigidity for optimum decoupling of the speaker from the floor. The solid MDF front, in conjunction with the enclosure optimized using FEM analysis, ensures accurate, precise bass response and significantly reduces cabinet reverberation. In addition to the mechanical damping by a foam cylinder, the B18 speaker has a bass switch to adjust the bass response according to room conditions and personal listening taste.
