Audio Lab AL 40 Loudspeaker

Recommended Posts

Hello everyone, Does anybody have any information on Audio Lab AL 40 speakers? I was given a pair that needs restoration but I cant find any information about them. The only clue I have is the back panel lable that states that their a 10 inch woofer with a 10 inch passive radiator, 5 inch mid, 1 inch dome tweeter, made in Poland. Any help would be appreciated. williamwilson64@tds.net

I have gleened a bit more informationas follows: I have recently been given a pair of Audio Lab Consort AL 40 speakers. These were imported from Poland by the Unitronex Corporation that had license to sell in the U. S. from 1970 to 1978. Does any one have any information, advertising literature, specification sheet, manual or any other information about these speakers or the product line of Audio Lab Consort? Thank you. <williamwilson64@tds.net>
