Its Evolution, Baby! Wharfedale EVO 4.2 Bookshelf Loudspeakers Do Dedicated Stereo and Versatile Home-Theater Duty, Feature 6.5-Inch Woofer and Deliver Impact, Imaging, and Detail Enjoy the impactful slam of a tower along with the superior imaging of a top-quality monitor with the Wharfedales EVO 4.2 bookshelf loudspeaker. Incorporating innovative engineering learned over its 80-plus years as an audio company, Wharfedale created a compact three-way model that produces layers of luxurious detail, a punchy midrange, and sonorous bass. Endowed with technology from Wharfedales Elysian flagship, it can fill an entire room with rich, colorful sound that belies its size. Inside, a 6.5-inch, bidirectional, black-woven Kevlar cone woofer incorporates a naturally self-damping material that reduces and distributes resonances to extremely low levels. In addition, a fixed, profiled phase plug ensures smooth acoustic roll-off that enables the drivers to seamlessly mesh with EVO 4.2s specially designed Air Motion Transformer tweeter and two-inch silk midrange driver. EVO4.2s crossover also deserves special mention. Using custom-designed Computer Aided Optimization technology during extensive listening tests, Wharfedale engineers carefully fine-tuned the crossover to the point that EVO 4.2 achieves balanced integration of its driver, woofer, and tweeter – allowing the speaker to practically disappear and draw your attention to the music program at hand. An all-rounder, EVO4.2 provides the detail audiophiles love and the dynamics home-theater enthusiasts crave. Measuring 17.9 x 9.8 x 13.8 inches (HWD) and weighing a shade more than 29 pounds, EVO4.2 claims a 90dB sensitivity that invites pairing with a wide range of amplifiers.
