Fun fact
It is still made today because so much vintage gear is still in use, and modern speaker cable adapters exist for it.
Tips & tricks
To connect vintage speakers to a modern amp, use a DIN-to-banana or DIN-to-bare-wire adapter; polarity is marked on the plug.
Philosophy
The sound of European living rooms in the 1970s. A plug that quietly kept polarity honest before anyone worried about it.
