is a Canadian loudspeaker
company founded in 1972
by Paul Barton. The company is named after Barton and his wife Sue. The company is headquartered in Pickering, Ontario
and is now part of the Lenbrook Group.
PSB Speakers produces many lines of speakers from the high end Platinum series to the entry level Alpha series. Their speakers are very well respected by audiophiles who prefer a flat frequency response curve.
Paul Barton has spent a lot of time during the past few decades researching his speakers in the anechoic chambers at the National Research Council in Ottawa.
