Mike,
I might be looking at this from the wrong angle. What cabinet contain this 90? a table top (B) or the a floor model ( X,H,or L). I'm thinking you have the B but seems like you've got the console set. Console has a larger speaker (10 1/2"). The chassis are the same.

Sorry was had 24A on my mind....
Yes John there is a easier one to follow in the library.
