Cambridge Physics 310 (c. 1982)
Not much is documented about the Cambridge Physics 310 beyond a single period review, but that review - Audio (November 1982, p.71) - gives a clear picture of the speaker. It's a three-way system. A 10-inch woofer in a sealed enclosure handles the bass, a 4½-inch cone driver covers the midrange, and a 1-inch dome tweeter takes over from 4 kHz upward. The enclosure is solidly built oiled walnut and weighs nearly 50 lbs (23 kg).
The same review notes that Cambridge Physics said the 310 was suitable for bookshelf placement. The reviewer found the mass a bit much for an ordinary shelf unless it was a very sturdy one. He also advised that if the system were mounted on a flat surface, it should be above a small child's head height (the sentence trails off in the surviving scan). Beyond that, the record is thin. No production years, original price, or further specifications have surfaced.
