Design
The Apogee Full Range uses full-range ribbon driver technology, incorporating foil midrange and tweeter components (FR-MRTW). This design eliminates the need for a traditional crossover network by using a seamless transition across frequencies. The speaker’s construction centers on a steel framework, providing structural support for the tension-sensitive ribbon elements.
Market
The ribbons in the Apogee Full Range were known to be very fragile, leading to high field service and repair rates. Replacement foil midrange and tweeter units (FR-MRTW) are available as tight-tolerance reproductions of the original parts, priced at $645.00 and including stainless steel bridges. Owner sentiment is strong, with some calling them the best speakers they’ve ever heard, though some found the bass response overly dominant.
