What is the DDD system?
Instead of a typical single woofer, it uses a structure where an internal 14cm driver and an 18cm passive radiator are positioned opposite each other to produce low frequencies.
The aim was to:
Extend bass even in a small size
Reduce cabinet resonance and vibration
Stabilize sound image localization
This is a sophisticated design typical of Technics at the time.
