The Wharfedale Diamond 11.2 bookshelf loudspeakers throw a wicked curve ball to all other models & manufacturers in its price class in the form of "box-free" performance connected to its sensual, curvaceous contours. That Diamond 11.2 also possesses an innovative driver system, leading-edge slot-loaded port, sophisticated damping properties, & exquisite finishes further freezes its peers in their tracks. Designed to draw you into your favorite recordings with a sense of refinement, clarity, & immediacy often alien to affordable speakers, the largest bookshelf model in the Diamond 11 Series offers palpable depth via a six-inch Kevlar mid/bass driver & silky smoothness by way of a 1" textile-dome tweeter housed in its own private cabinet. If that wasn't enough, Diamond 11.2 also allows freedom of placement since it performs at an optimal level even when positioned close to rear walls.
Able to play with serious low-end extension, pinpoint detail, & revealing openness, the Stereophile Recommended Diamond 11.2 prides itself on being an all-rounder equipped to handle any type of music with equanimity. It's everything you could ask for in a model of its size, and far more when you consider its price. Inside, curved multi-level cabinets, internal bracing, and fiber-lined walls go to extra lengths to defeat resonance and operate without coloration. And Diamond 11.2's advanced drive units tout massive ceramic magnets for high sensitivity as well as highly linear motor systems for minimal distortion. Read more about the advancements inside Diamond 11.2 below and you'll further understand why this is anything but a typical bookshelf unit.
"After two months of living with the Tidal Akiras, I was pleasantly surprised by what the Wharfedale Diamond 11.2's gave me at 1/359 the price. ...Couple these Wharfedales with something like PS Audio's Sprout100 integrated amplifier that also costs $599, & you have the basis of a good-sounding system for $2 short of $1200."

Cutting-Edge Drivers Lend to Clarity, Immediacy, & Purity
Woven Kevlar cones bond to a super-lightweight surround made from hi-tech foam that delivers remarkable clarity and expression. The foam surround is manufactured in-house with a U.S.A.-made "water-resistant polyester foam" that has proven longevity, higher elongation, and better tensile, tear strength, and ozone resistance. The cones are driven by copper-clad aluminum coils, which surround a custom-shaped one-piece pole plate fitted with a copper cap to reduce inductance and linearize the magnetic flux. A specially designed basket, with a large open area behind the cone, holds together the driver assembly. The basket's rigidity improves transient impact and the big open area reduces early reflections while allowing the internal cabinet absorbent to do its work.
Wide Frequency Response Tweeters with Oversize Ceramic Magnets
Developed specifically for Diamond 11 Series, Wharfedale's Wide Frequency Response tweeter incorporates its own cabinet in the form of a rear chamber damped with fiber filling. The design provides a low resonant frequency below 800 Hz, ensuring the usual distortion heard from such resonance gets buried deep below the musical output. An over-sized ceramic magnet, chosen to give a smoother sound than common neodymium types, attaches to a vented pole piece with copper cap. Taken together, the features contribute to a wonderfully lucid midrange and smooth, pure, richly defined high-frequency detail.
Curves That Look Great & Contain Sound-Enhancing Properties
The main enclosure of each Diamond 11 Series speaker utilizes a multi-layer sandwich of woods of differing density to subdue the identifiable characteristics of the cabinet sound and let the advanced drivers speak for themselves. Critical bracing of the cabinet panels contributes to the eradication of audible resonance, as does the curving of the cabinet walls to provide a non-boxy shape. In addition, the cabinet walls are lined with a specially developed internal fiber chosen for its outstanding absorbent qualities across a wide bandwidth. The result: You hear the drive unit output unsullied by unwanted colorations caused by panel vibration or internal resonances, meaning you get more musical detail & texture.
Feel the Bass: Slot-Loaded Distributed Port
Instead of employing a standard circular reflex port, an updated version of Wharfedale's sophisticated Slot-Loaded Distributed Port augments bass performance. An internal port tube, with precisely curved openings to smooth airflow, opens into a slot formed between the cabinet & plinth – reducing the turbulence and chuffing suffered by conventional ported systems (and caused by the sudden outrush of high-pressure air into the low pressure in the room). You experience a natural recreation of the fundamental notes of bass instruments, matching the realistic sound of the midrange & treble characteristics. The design also allows you to position Diamond 11 speakers closer to a rear wall than is possible with conventional rear-ported speakers.
