The Fusion Reference Bookshelf is a high performance ported speaker system employing a state-of-the-art crossover, drive units, cabinet materials, and interior coatings. This combination results in ultra low coloration with zero distortion! Extreme linear response, with less than 2 db variation and low distortion, makes it ideal for near-field monitoring. The Dyna™ silk dome tweeter has it’s own back enclosure for low resonance and coloration. The patented 7” Seas™ Reed woofer has a pure copper pole and advanced motor system with extremely high acceleration to provide the necessary “stop/start” required for the highest level of mid-range fidelity. In addition, shorting rings and a raised spyder provide a very tight and controlled bass response. Available in various custom finishes.
