McCauley's M88, pictured here, is a high output precision subwoofer system designed to scale from single unit deployments to large scale sound reinforcement applications. The M421 subwoofer, meanwhile, aims to set a new standard for low distortion, high impact, bass reproduction.
The M88 is designed to be easy to move, truck-pack and stack for events of all kinds. Capable of reproducing extended low frequencies, the M88's low frequency coupling technology and enclosure design makes this system well-suited for large format sound reinforcement applications. The M88's loudspeaker complement consists twin air loaded 18" cone drivers.
The M421, meanwhile, has a continuous power handling capacity in excess of 12,000 W (24,000 W instantaneous peak) and a measured peak output of 143 dBSPL at 4m within its operating band. With a flat response from 20 to 100Hz and a total weight under 490 lbs., the M421 promises a new level of low frequency energy for its size. The design features four 21" long excursion neodymium motor transducers with 6" voice coils that exhibit near-linear BL product through the entire range of cone motion. The drivers are configured in an isobaric connection and coupled to an FEA optimized acoustic transformer.
