High Output Series Subwoofer
The twin eighteen High Output Series HOS 218 is intended for extreme
applications in large control rooms where SPL requirements are
paramount, but well-behaved low frequency reproduction is essential.
The large format (24" x 47" x 34" deep) slot-loaded design, under
the control of the SBX crossover, provides
peak SPL exceeding 130 dB over its entire operating band to below 30Hz.
