 Model MW-2

The following photos are a pair of MW-2's that I owned and refurbished (cabinet refinishing, re-foaming woofers).
 
 
 
 
Above: Woofers, after being re-foamed.  Note that this driver is customized for this application: under the felt dust cover there is a large number of lead shot held by epoxy to adjust the driver parameters.
 
 
 
Above: original crossover/terminal plate, inside the back of the cabinet.  The parts are covered in what looks like PL construction adhesive, so it is virtually impossible to work on the crossover without destroying it.  Note the motor start capacitors, as well as at least one other electrolytic cap, a couple air core coils, and a number of 10 watt sand cast resistors.
