Spider Ranch Productions, located in San Francisco, CA, recently purchased McCauley Sound‘s new M421 Quad subwoofers to augment its existing inventory of McCauley Monarc MLA6 and MLA3 main line array systems and M88 2 x 18 subs.
The M421 incorporates four 21-inch long-excursion neodymium motor transducers with 6-inch voice coils, with the unit’s continuous power handling capacity in excess of 12,000 watts (24,000 watts instantaneous peak) and a maximum peak output of 155 dB SPL (at 1 meter).
Spider Ranch owner Alex Moran explains, “What makes the M421 special is that it adds a powerful bone-crushing low end that I have never heard before from any sub in all my 30 years of doing concert audio.”
Moran also notes that the M421 significantly increases his ability to handle a variety of large shows that demand heavy low end SPL. “It doesn’t just get loud, the fast response results in a highly musical experience.”
McCauley is now shipping the M421 worldwide.
