SD 1 speaker Tweeter and Crossover


the entire speaker is constructed from gravity-cast PBM, a kind of synthetic resin which is both rather heavy and very inert.
The speaker is a 3 way design, the bass being handled by a pair of 8" doped paper units at the bottom of the cabinet. These are internally separated from the rest of the speaker and are reflex loaded by a small port on the rear. The midrange unit is an 8" polypropylene unit which is driven 'semi-active'. The rest of the treble is then handled by a Monacor magnetostatic hybrid ribbon tweeter.
