Special Features

Today I pulled the woofer on one and took a look around in them. The big surprise is that the woofer has what looks just like the normal aluminum frame that I'm getting used to seeing on Cantons but actually it's a plastic frame! It looks like it might be some kind of glass reinforced plastic, but plastic nonetheless. The speaker box is also a 2 piece plastic cab with the front baffle being the 2nd piece and is removable, being held on with 6 screws.

The caps are the typical Canton caps made by Wego and don't have any value markings other than 23vac, just part numbers. The part numbers for everything are as follows:

Tweeter = 2746
Woofer = 1368
Cap (tweeter) = 3779
Coil (tweeter) = 2097
Cap (woofer) = 1228
Coil (woofer) = 2862
And 2 resistors, 12 ohms and 150 ohms.

I'm putting a list together of the cap numbers from all the different Canton speakers that I and some friends have and will be writing Canton to ask if they can identify them. I'll post when I get an answer just to put it on record. Wego apparently specializes in producing OEM caps etc made to spec for the end user. And I've already found out that pulling and measuring a cap with an LCR meter doesn't help much because some (most?) of the caps are made to some non standard values, such as what I found in a CT 80. A cap with PN 1615 measured 139.9µF when I pulled it. I found out in a German HiFi forum that that cap has an original value of 120µF. So this is turning into an interesting bit of research.
