Denon SC-3000 (1981)
A high-end 3-way sealed bookshelf speaker system developed from Denon's flagship SC-5000.
Overview
The SC-3000 is the compact counterpart to Denon's top-tier floorstanding SC-5000. It inherits core technologies from that flagship and puts them in a bookshelf cabinet. It is a 3-way design with a sealed enclosure, and the frequency response runs from 30 Hz to 30 kHz. The drivers use proprietary diaphragm materials and a symmetrical layout.

Design
The SC-3000 uses a hermetically sealed enclosure made of hard particle board with a walnut natural wood finish. The 30 cm cone-type woofer has a High-M/P diaphragm made of wood pulp and refined ramie fiber, reinforced with concentric and radial ribs. The midrange is a 10 cm cone-type squawker with a double-layered High-M-T diaphragm. The folds of the woven fabric sit at 45 degrees to each other. The 5 cm tweeter has a semi-dome diaphragm with a special aluminum alloy center and High-M-T cone. All drivers use ferrite magnets and aluminum die-cast frames. The network section has direct wiring and one-point grounding. The unit layout is symmetrical.
