The PMC Loudspeakers MB3-A is a 3 way ATL active reference monitor - 20Hz - 25kHz frequency response, 128 dB max SPL. Sold as pair
Whether mounted in soffits or on stands, the MB3, with its distinctive 12-inch Radial bass driver, is ideal for medium-sized recording, mixing, mastering or outside broadcast facilities, or as rear surround speakers in larger multi-channel recording studios, film soundstages, or post-production houses. It produces an extremely smooth frequency response extending from 20Hz to 25kHz thanks to its ATL technology, and is also capable of producing high SPLs, to a maximum of 126dB, but without the distortion and loss of definition that are frequently associated with a device of its size, and without becoming fatiguing when used for extended periods.
As with all PMC models, there is a matching low-profile centre channel (MB3-C-A) for use in surround configurations. Dedicated subwoofers are not a necessity, as the MB3-A cabinets already cover the 20-60Hz sub-bass frequency range with ease. For this reason, 'PointOne' channel inputs are included on the Control 1200 to accommodate the LFE or sub channel from multi-channel mixes.
