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
60 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’s
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.

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.

"I must admit that I have personal knowledge of the longevity
of ASL's products. A friend of mine has owned a pair of Audiosound
speakers and an amplifier, since we were both at high school together.....
and that, I regret to say, is something more than 20 years ago.
His system has always worked perfectly and he has always told me
that he has never seen any reason to upgrade."
