This is possibly the coolest music video ever made!

I can rebuild most low frequency speaker drivers and midranges built in the last hundred years. However, some drivers use metric or odd dimensioned parts which are just about impossible to obtain.
I can refoam almost anything except strange rectangular drivers.
I can diagnose and repair any form of problem with a speaker's crossover circuitry.
I can turn old speakers with good cabinets into clones of HUMAN products.
I can rebuild and repair musical instrument and PA drivers. These sometimes cost a bit more than the chart in the price list, since they often use rather expensive, proprietary or incredibly high power handling components. Sometimes, they just need to be "fixed" - I have seen many with small tears, screwdriver damage, or broken "tinsel" flexible leads. These can often be repaired for much less than the cost of full reconing.
