Speaker replacement

Many original speakers now look like this one below:

No wonder that the sound quality leaves a bit to be desired

Earlier models use 10 cm speakers while later models (from around 1986 on) use 13 cm speakers.
The speaker frames are dimensionally identical except for the center cutout, so an upgrade to the larger 13 cm speaker can be done without having to modify the doors.
I upgraded to 13 cm models and had good experience with Pioneer TS-G1323i speakers. The improvement in sound quality was astonishing.

I bought a 114 mm hole saw to reproduce exact copies of the later speaker frames.
Should you need the later frames, I can provide these.
