Back in 1983, Brock Adamson started building loudspeakers. Thirty years later, Adamson Systems Engineering is a name associated with big speakers and bigger tours. Time to look back then…
1983-1993
MOST IMPORTANT GIG Brock Adamson, founder and president of
Adamson System Engineering, was hired as the events site-wide audio
The ‘game changing’ MH225
consultant for the 1986 Vancouver Expo. “Transportation and
Communication: World in Motion – World in Touch”. It was only the second time that Canada held a world fair and the last one to be held in North America. It was the first recognition that Brock received as a world- class sound designer.
BEST PRODUCT:
M200 DRIVER/MH225 CABINET The M200 and the MH225 c.1988 both get a mention because “they are two parts of a whole”, says president and CEO Brock Adamson. The MH225 was the

MILESTONE: SETTING UP THE ‘SHOP’ “I remember the ’80s as a learning experience,” says Brock. He started designing speakers several years prior to becoming a partner at Vancouver’s well known hire company Rocky Mountain Sound. After his experience at the Vancouver Expo, Brock decided that to advance his designs he had to go where he had the best access to the most current technology, machine tooling and manufacturing in the country. And so he moved to Ontario and opened up the Adamson ‘shop’.
first Adamson cabinet to pair the M200 mid-range compression driver with an acoustic waveguide. Adamson’s research, combined with the principals from Dr Earl Geddes’ publications on Waveguide Theory, allowed the firm to introduce the first Acoustic Waveguide in a commercial loudspeaker system. “The benefits of these early waveguides included lowered turbulence, improved directivity and better loading. The M200 and the waveguide was a quantum leap in maximising the SPL without distortion.” The MH225 truly was a game-changer,
says Brock. “It was capable of extreme output without sacrificing clarity throughout the frequency range, with excellent directivity.” Audio engineers everywhere took notice, putting the Adamson brand on the map in sound reinforcement technology.
