The Vanishing 70RT packs impressively large sonic performance into a cutout size of just 6-1/2 inches, while practically invisible grilles and a minimal-flange design offer a truly unobtrusive design. Packed with innovative technology, but thoughtfully priced, this speaker makes an excellent stealth rear or side surround speaker for home theater installations on a budget. The lightweight polypropylene cone and sensitive silk dome tweeter can be angled for superior off-axis performance. Use the reflective room compensation switch to digitally compensate for “reflective” rooms, giving you extraordinary placement flexibility. The innovative addition of the woofer driver behind the main speaker adds unparalleled depth and dynamics.
