Sony (unknown model)

These smaller 2-way speakers by Sony were in pretty good shape when I found them, except for damage in one of the 6" woofers.
It turned out that the damaged (the center dome had fallen off).  

Restoration:

• Cleaned all dust and polished the exterior surfaces

• Repaired one woofer (glued center dome back on)

• Electronic test:  excellent;  see test report below

• Listening test:  very good

These smaller speakers are a little weak on deep base (below 100 Hz).  They are excellent as-is for background music or general listening. 
For home theater or serious audiophile listening, a subwoofer should be added.
