The Bang & Olufsen BeoLab 90 is a flagship, digitally controlled, powered floorstanding loudspeaker created to deliver ultra high-fidelity sound for demanding home listening. Each speaker integrates 18 Scan-Speak drivers—seven 1" Illuminator tweeters, seven 4.5" Illuminator midrange units, three 10" Discovery woofers, and one 13" Revelator front woofer—driven by 8,200 watts of built-in amplification via 14 Bang & Olufsen ICEpower AM300-X modules for the tweeter and midrange drivers and four Heliox class-D amplifiers for the woofers. Advanced DSP with two Analog Devices ADSP-21489 processors enables Active Room Compensation, Beam Width Control (Narrow, Wide, Omni) and Beam Direction Control, allowing the speaker's radiation pattern to be tailored to different rooms and listening positions. The BeoLab 90 offers extensive connectivity, including Wireless Power Link and WiSA, plus wired USB Audio, S/PDIF coaxial, Toslink optical, Digital Power Link, and analog inputs such as B&O Power Link, RCA, and fully balanced XLR on the master speaker. The enclosure uses a robust cast-aluminium internal structure combined with oak wood and fabric finishes, and each speaker measures approximately 1253 mm (H) x 735 mm (W) x 747 mm (D) and weighs about 137 kg (302 lb). Frequency response is specified from below 12 Hz to above 43 kHz, and maximum output is rated up to 120-123 dB SPL at 1 m for a single speaker, with up to 126 dB SPL per pair, making the BeoLab 90 one of the most powerful and technologically advanced domestic loudspeakers available. Originally introduced to celebrate Bang & Olufsen's 90th anniversary, it continues to serve as the brand's reference floorstanding loudspeaker.
