It would be worth a try to take a small speaker and cut four pie-shaped 
segments from the cone, leaving four strips about 1/4" (6.4 mm) wide to 
hold the voice coil in position.  You might also try something like the 
zero-beat indicator that's been discussed here to give a visual 
indication of correct tuning.
