Design
The CA-70 has a hidden passive radiator system called "Acoustic 3D" under the tape deck. Air reaches it through ports on the sides, where the detachable speakers connect to the central unit. The radiator only works when the speakers are attached. It has a foam surround, and so do the main speakers. You also get a detachable full remote control, a hearing protection function (Ear Guard), and a Super Bass feature. The full metal body adds structural integrity and acoustic isolation.
Market
One CA-70 was listed for $100 approximately three years prior to the listing date, typically sold as non-functioning for parts or repair. The usual problems are deteriorated foam surrounds on both the main speakers and the passive radiator, which need refoaming. Controls need cleaning, and the tape deck belts need replacing. A blown fuse is another possible repair. The service manual is available for purchase.
