The Vandersteen 3A is a higher-end variation on the theme established by the company's first loudspeaker, the 2C. The latter is still available, though much updated into the current, highly popular 2Ce. A four-way design, the 3A has separate sub-enclosures for each drive unit; the whole affair is covered with a knit grille-cloth "sock" with wood trim end pieces. A rear-mounted metal brace allows the user to vary the tiltback—an important consideration for best performance with this loudspeaker.

The Model Four is the largest model in KEF's current Reference series of loudspeakers, discounting the R107/2 Raymond Cooke Special-Edition (reviewed in a follow-up in October '95). It's also the largest KEF model that uses their Uni-Q® loudspeaker configuration. When I visited the KEF factory last October with a group of audio journalists from the US, KEF emphasized the importance of Uni-Q technology to their future plans. They consider it proprietary, and intend to enforce the worldwide patents they hold on the design. One look at KEF's current line will be enough to tell you why they're so serious. Uni-Q drivers may be found not only in most of the Reference series, but in most of their other models as well. The most significant exceptions: the Raymond Cooke series, a few inexpensive models, and their THX-certified loudspeaker system.

Americans might be forgiven if they haven't heard of Epos. A small, British specialist loudspeaker manufacturer, it was founded in 1983 by its designer, Robin Marshall—an ex-BBC engineer and a onetime consultant to Monitor Audio, according to Roy Hall of Epos's US importer, Music Hall. Their first model, the ES 20, didn't make it to the US, and was apparently a bit too pricey in the UK to make much of a splash there (about £700, $1300 at the current rate of exchange—a mint in a country with the patent on sub-$500/pair (UK prices!) two-ways). In 1986 or thereabouts, the new, smaller ES 14 was introduced, using updated versions of the same drivers in a smaller, ported cabinet. Music Hall only recently began importing the Epos into the US.

High-end-audio manufacturers are both more and less adventurous than their more mainstream contemporaries. While mainstream-audio manufacturers will almost invariably change their models every year, the changes are more often than not cosmetic—at least in between successive models. High-end manufacturers, on the other hand, will keep the same model in the line for several years, but make cosmetically invisible refinements along the way.
