Yes, the 89 uses either a K-7 or a K-21 speaker. The field coil and pot of the K series speakers are larger than those of the S-7, but the field coils of both the K-7/K-21 and S-7 are rated at 65 mA. The K-7/K-21 will produce a bit more bass due to the larger field.
Remember, the model 60 was a cheaper radio than the 89, so it had a cheaper speaker with a smaller field and pot.
Don't forget Rich Stamer in NJ if you decide to have one of those speakers reconed...

Some of us here on the Phorum have used Rich's services in the past and I'm not aware of anyone who has had a single bad experience with his work.
