AudioSound Laboratories web site (July 12, 2009): Audiosound Laboratories (ASL) is a totally Australian owned manufacturer and retailer with over 30 years experience in designing studio monitoring amplifiers, loudspeakers, tuners, as well as filters and signal processors.
Company founder, Mr. Ron Cooper, works very closely with Mr. A.N. Thiele (Thiele/Small parameters) who has written over sixty international engineering papers on loudspeakers, filters, amplifiers and numerous other electronic topics.
Very highly respected in the international electronic community, much of Mr. Thiele's work has become legendary throughout the world through his early paper on loudspeakers back in 1961, which was reprinted many years later (1973) in the journal of the American Audio Engineering Society (AES).
The accurate, extended, bass-end alignments of ASL loudspeakers are due to this close association with Mr. Thiele who wrote and customised the computer software which has been used by ASL for many years.
ASL's loudspeakers, amplifiers and electronics have been used by the Australian Broadcasting Corporation (ABC) & numerous broadcast stations and major recording studios around Australia for over 30 years, and eight of our loudspeakers have received the prestigious Australian Design Award. All loudspeakers and monitors are hand made and each matched pair undergo individual response tests. No mass production techniques are used. Our latest crossover technology in certain models features precision high slope, constant phase filters which virtually eliminate lobing in near-field monitoring situations.
ASL, as acoustic consultants, custom design special high-slope, cross-over/filters, subwoofers and active crossover systems to suit particular needs. Ask us about our total design and manufacturing solutions for specialised requirements where precise monitoring is required.
