Hi
Can anyone confirm the model of the mid/bass drivers used in the above speaker?
I thought they were Audax HD20B25 H
but I have now seen that there are a variety of Audax HD20B25 then various suffices (J, E etc.)

Thanks

Usually Audax stamped the model number on the back of the magnet structure.
It can be hard to make out as it wasn't very dark printing.

Thanks but unfortunately there is a large lump of wood firmly stuck to the magnet which in turn goes against back of the cabinet.
