The Biema Beta II (bII) active line array has a twin 12” bass unit containing a built-in fan-cooled high power amplifier and adjustable active crossover for fine tuning the system output. The four mid/high cabinets each contain twin 6.5” drivers and two 2” PA tweeters and have a variable vertical angle adjustment with locking pins for tailoring the sound coverage to suit the venue. May be hung from a speaker rig using the built-in hardpoints or mounted to a ceiling with the C1221 bracket.
Multiple units may be daisy chained together to form an even larger PA system. Supplied as a complete system, with active subwoofer cabinet and four mid/high cabinets, in two sturdy flight cases with wheels.
