I have a pair of Yamaha NS-1000M speakers and am in the process of conducting an extensive refurbishment/update of them.
Replace all capacitors with polypropylene (same value) - improve tolerances/matching
Externalise crossovers
Make stands
Improve bracing of cabinet/bass driver
Repair/improve mounting of mid driver
Remove L-pads (replace with fixed resistors)
Make anti-diffraction rings for tweeter and mid
Replace/remake badges
Remake rear connector panel
Remake all gaskets
Replace all cables
Smooth and refinish all driver rebates
Replace rear panel wood screws with M4 T-nuts and bolts
Refinish cabinets in high gloss black laminate
If interested, step-by-step pictures and description can be found here (updated as work progresses):
