I bought some "vintage" canton speakers and now i have some issues with them..

With a coil and a cap, that's a 12 dB/octave rolloff. With a crossover point of 900 Hz, the midrange should be an additional 12 dB down at 450, another 12 dB down at 225 Hz, and another 12 dB down at 112 Hz.

So, it would be normal to hear sound from the midrange at 400 Hz; it will just be significantly lower in volume, since it will be getting less than 10% of the power of a 900 Hz signal (10 dB change = 10x the power required).

Ok, since no one was willing to help i looked at this once again and i think i got it right this time. This is what i came up with , please someone confirm
if this is correct.

So I have finally had time to look this over. IF I make the guess that the leads to the woofer coil (#1550) are connected in series from the woofer plus to the input plus, then yes, the schematic looks good to me. I wouldn't have to make a guess if you had taken the time to remove that cork washer so we can see for sure where the coil is connected. Logic says in series for a woofer but why make guesses when it's not nessicary?

Interesting that the mid appears to have a 2nd order cross to the tweeter (3690 cap + 1549 coil) but only a 1st order cross to the woofer (2096 coil).

Did you contact Canton and ask about a schematic? If they still have one you could read the coil values and then use Xsim to model the whole thing.

Most Cantons are a bit hot IMO.

I've had the opposite experience, better bass than expected for their respective size.
