By design, this is a classic 2.5-band speaker, while the woofer and woofer/ midrange speaker are "borrowed" from the textbook shelf model B10, which has been successfully produced since 2011. The case is just over a meter high and weighs 35 kg. It is made of MDF sheets with a thickness of more than 30 mm, and the midrange/treble speaker bundle is additionally reinforced with an aluminum panel.
The model is a three-lane floorstanding loudspeakers, the dimensions of each column are 210 x 1165 x 460 mm. The speaker set includes an Air Motion Transformer (AMT) ribbon radiator, a 17 cm midrange driver with a fiberglass diffuser, and a side-mounted bass speaker with a 32 cm double-layer cellulose cone and a powerful neodymium magnetic system.
The Burmester BX100 speakers offer true High-end sound with luxurious full-spectrum detail and brilliance. The model is designed according to a four-band scheme and guarantees reproduction in the entire audible frequency spectrum (from 20 to 30,000 Hz). The modular design of the system makes it possible to radically reduce body resonances.
The towers are 1,433 mm high, weigh 195 kg and, according to the developers, "make an innovative leap in sound quality." An 18-cm speaker is mounted on an aluminum plate in an MDF case. Twitter has been adapted to the new acoustic conditions. Drivers with oval coils are responsible for the medium frequencies. A large magnet plays an important role in high sound quality.
The Burmester BC350 acoustics are equipped with two 32 cm woofers for bass, two 22 cm drivers for midrange, and two Air Motion Transformer speakers sound the high frequencies. The speakers can operate in two modes - Pure, optimized for audiophiles (focusing on resolution).
