Burmester B18 : Speaker
The B18 loudspeaker has been developed as a 2½-way bass reflex speaker with a front-firing design and is a universal sound talent: space-saving, yet at the same time extremely musical and dynamically thrilling. The high-frequency reproduction benefits from the ring radiator which is custom-made for Burmester and guarantees optimum clarity and resolution. The low-mid and mid-low drivers are a derivative on the basis of the proven chassis which has already earned the B10 compact speaker an impressive sound performance. The highly complex frequency crossover sits in an isolated enclosure chamber, just like the low-mid driver whose own sealed compartment yields an outstandingly clean mid-frequency performance
