The Burmester BC150 is a large floorstanding loudspeaker from the German maker of high-end electronics and loudspeakers. A low nominal impedance and a very heavy cabinet define it.
Key specs that matter
The BC150 covers 34 Hz to 20 kHz within 3 dB. Sensitivity is 88.5 dB at 1 W and 1 m, and the nominal impedance is 3 ohms. Burmester gives an amplifier requirement of up to 400 W. The cabinet measures 30.9 x 143.3 x 60.1 cm, and each speaker weighs 180 kg.
Pairing
The 3 ohm load and the 400 W requirement make it a speaker for a high-power amplifier that is rated to drive low impedances. Burmester's own power amplifiers and preamplifiers are the natural partners.
Alternatives
Burmester also makes the BC350, another floorstanding loudspeaker in its range.
