Dear Mr. Troels,
I enclose photos of upgraded speakers. I attached 8 mm thick duralumin
plates to the front baffle, 20 mm under the mids, I glued 3 mm leather
to the surface. The sound is significantly better, it is fuller. has
more more details, all tones have better contours, especially the bass
is more accurate and fuller.
Best regards,
Juraj
