Versatile Performance for Dedicated Listening and Home-Theater Applications: High-Value Wharfedale EVO 4.1 Bookshelf Loudspeaker Plays with Boldness, Heft, and Coherency What happens when flagship audio technology trickles down to far more affordable designs? You get gear such as Wharfedale's overachieving EVO 4.1, a high-value two-way bookshelf loudspeaker that produces the kind of big, bold sound you'd expect from a much larger model. In music applications, EVO 4.1's silky-smooth tweeter and responsive bass driver deliver hours of fatigue-free listening. And EVO 4.1's transient response remains quick enough to deliver the sonic complexity rendered by a top-flight home-theater system. While EVO 4.1 is undoubtedly the sum of its total parts, its five-inch, bidirectional, black-woven Kevlar cone woofer cannot be overlooked. It incorporates self-damping material that reduces resonances to extremely low levels. In addition, a fixed, profiled phase plug ensures smooth acoustic roll-off that enables the driver to seamlessly mesh with an Air Motion Transformer tweeter. Taken together, these elements allow EVO 4.1 to excel when it comes to wide dispersion, articulate bass, and generous soundstaging. EVO 4.1's crossover also deserves special mention. Using the company's custom-designed Computer Aided Optimization technology during extensive listening tests, Wharfedale engineers carefully fine-tuned the crossover to the point that EVO 4.1 achieves balanced integration of its woofer and tweeter – allowing the speaker to draw attention to the program at hand. Measuring 13.2 x 8.3 x 11.6 inches (HWD) and weighing slightly more than 17 pounds, EVO4.1 fits in tight spaces while its 87dB sensitivity means it can be driven by a wide range of amplifiers.
