I am selilng a pair of very mint and rare East German studio monitor speaker driver model Schulz TH315/1.
Coaxial in design and time aligned, it uses a 12" woofer cone, a felt fabric neumatic filter and a aluminium tweeter. This pair comes with all orignal crossover with MP capacitors and RFT inductors, a frequency response graph of both units to show matched response, and 20 pages of documents about the th315/1 in german language.
Condition is 9/10, with only slight peeling of the hammertone paint on the back near the magnet bell on one unit, and overall condition is as good as you can dream of.
These drivers are now one of the rarest on earth. Its ancestor Eckmiller 015 field coil is almost impossible to find and is rarer.
Audio guru Thorsten Loesch raved about this drivers and regarded it as the top speaker drivers ever produced.
Age is about 30 years old I think.
