Shadow cabinets

摘要

Why has no other tiny speaker come along to match the huge stature of the BBC LS3/5A? Ultimately, it's because, in the 1960s and '70s, the BBC could indulge in an extended R&D process that would have been impossible for any commercial speaker maker. As with other BBC loudspeakers such as the LS6 (and the related Spendor BC1), the LS3/5A benefits from its costlier and harder-to-build thin-wall 'lossy' cabinet, which uses (in this case) 9mm birch ply, rather than greater thicknesses of cheaper engineered wood. Recently, the full-range metal-cone drive unit specialist E J Jordan announced a foray into complete speakers with its new Marlow model, inspired by setting Jordan units in LS3/5A cabinets.
