His intention was simply to produce cosmetically appealing loudspeakers that accurately reproduce music while representing value for money. M.Q. Cabinets Limited, Monitor Audio's cabinet manufacturing facility, was established in 1976, allowing Monitor Audio to fully control the quality of workmanship that goes into every pair of their loudspeakers. M.Q. Cabinets rapidly established an impressive reputation for the quality of their solid wood and real wood veneered cabinets. So much so that they have produced or currently produce, cabinets for every well known (and not so well known) British loudspeaker manufacturer. Will be carefully packaged and sent with track & trace code. Pick up also possible upon agreement
