I’ve just picked up a pair of Technics SB-MX100D which a friend was about to put in the skip. They cabinets and stands are mint beautiful oak veneer but the surrounds of the bas drivers are completely disintegrated. One driver is somewhere in Singapore looking for a replacement and at the moment I don’t even know if it is retrievable or whether it has been disposed of.
I'm told these are approx 1992 vintage and were not cheap.
My question to you all is should I even try to breathe some life back into these beautys?
I will find out if the missing driver is still alive and if so I think I might try to fix new rubber surrounds but in case the driver is gone for good
Can anyone suggest a suitable driver replacement given the following baffle cut out dims
Overall outer flange recess 190mm diameter
Baffle cut out inner hole diameter 165mm
Fixing holes 6 No equal on pitch circle diameter of 180mm (I can drill new holes if drivers are 5 holes etc but very limited scope to play with the diameter
Original driver was Technics EAS18PL100A
Tweeter is Technics EAS25KH100A
Tweeter is 6 ohm, Bass Driver may be 8 ohm or 6 ohm the print mark is fuzzy
Here’s some stuff from a German website via Google Translate
