Mb Quart\'s Vera line has been mercilessly underestimated since its launch! Very heavy and high-quality cabinets, state-of-the-art and highly resilient chassis technology as well as the best crossover equipment distinguish these loudspeakers. Grills are brand new, never opened/used.
The Vera\'s 6-inch woofer is an all-new design featuring a 3-inch, lightweight, copper-coated aluminum voice coil, wound on a titanium former to fortify the driver\'s power-handling numbers. Why titanium? It\'s lighter, stronger, and dissipates heat better than the more-common aluminum, fiberglass, or Kapton formers found on most high-end designs. The voice coil is further cooled by the aerodynamically designed polymer composite cone that encourages air flow, as well as by an oversized air vent near the magnet system (MB Quart uses similar heat dissipating techniques in the tweeter). The driver\'s aluminum basket is thermally coupled to the die-cast-aluminum central baffle (between the woofer and tweeter); that hefty metal baffle draws heat away from the cabinet\'s interior. The engineers placed the baffle on a special gasket to minimize the energy transfer from the speaker\'s moving parts—the woofer and tweeter—to the cabinet.
Titanium dome tweeters are a longstanding MB Quart design feature, but the Vera\'s high-frequency driver is the most sophisticated and expensive tweeter the company has ever manufactured. This titanium dome uses a soft Polyolefin Copolymer surround to control \"oil can\" effects, ringing, and other nastiness that plagues some metal dome designs. A felt-lined, egg-shaped chamber on the tweeter\'s backside minimizes resonance.
The Vera cabinets\' gracefully curved side panels and luminous veneers wouldn\'t be out of place on a $10,000 speaker. I attribute the cabinets\' uber-solidity to the 25-millimeter-thick (nearly 1 inch) high-density-fiberboard
High quality crossover parts - clarity caps, air core inductors, high quality resistors.
Cabinet has anti-resonance foam padding on the interior and is well packed with poly-fill.
