Sonics AS-337 #2

I bought this pair from an old Army vet.  The wood is nice, but scratched and has a few deep scratches.
This is a 3-way sealed speaker system with 5 drivers.  Woofer is 10" in diameter.

The Sonics brand was made in Japan in the 1970's and sold in American military exchanges.  

Problems discovered:

• One horn tweeter was missing

• Sound was very muddy and flat

• Some deep scratches in the finish, too deep to fully repair.

• Original lattice grills were removed.  The fabric was kept and in excellent condition.

Restoration:

• Cleaned all dust

• Removed tape and most stains

• Replaced the crossovers.  I left the original crossovers in place, in case a future owner wants a 100% original restoration.  As a result, the 3 buttons on the control panel are not functional.

• Replaced the missing horn tweeter

• Listening test: very satisfactory

• Electronic test:  satisfactory: see FR report below

• Touched up and polished the finish.  

• Sound is good; the audiophile will find it a little weak from 50 Hz to 100 Hz but easily corrected with equalization.
