All Sony speakers made in Canada used Japanese drivers from companies like Foster or Pioneer. Drivers were shipped from Japan, but the enclosures were Canadian made.

Bass driver looks like some made by RSC (Radio Speakers Canada), these all look like North American drivers, not Japanese.

My Dad oversaw pretty much all speaker manufacturing here in Canada for Sony. According to him, all drivers were Japanese, made to Sony specifications.

Not the ones in the boxes pictured. The 4 character code strating with D is a Canadian OEM code. Built to Sony specifications likely.

Dave,

You're probably right. I prodded my Dad a bit more, and now he's remembering a lot of lower cost speakers were outsourced. He was in charge of the speakers made by Sony, but he does not have much information on the outsourced product.

DavidL thanks! so the timeline has us in the disco era

planet10 i think your speaker sleuthing abilities are amazing is this RSC stuff or does it come from the old Cambridge Speaker plant in Waterloo the frame reminds me of other stuff like Electrohome,Viking etc. or is this early McBride stuff (the hint there comes in the form of the frame being pre stamped for 70v x-former mounting).
it appears the numbering on the drivers is a packaged set:
dwe7 pack : woofer-DWB6 SS610B
mid-DWH6 SS610M
tweeter-DWH6 SS610T

so the last thumbnail shot is of a 5 inch hole, on which a 6 inch(eff. cone dia) 7.25(frame) bass driver was mounted (baffle thickness 5/8) not to mention a layer of perforated plastic and a grillcloth.
now we need to track down the guy at the plant who said: that how i was told to make them!

if your father was involved with manufacturing/distribution for Sony i'd really like to communicate with him about his tenure/time there as i'm trying to gather info on the canadian electronics manufacturing sector in that era.

sincerely
