Cut right to the heart of your music with the Wharfedale Diamond 11.3 tower loudspeakers. Bolstered by a six-inch woofer & 6" bass/midrange driver, the two-and-half-way floor-standers play with an authoritativeness, immediacy, transparency, and dynamic uncommon anywhere near its price class. Proudly expanding on the Diamond Series heritage originally established more than three decades ago, Wharfedale thoughtfully considered every aspect of Diamond 11.3 on the inside and out so that it performs with optimal results. Brand-new drive units with high-tech foam surrounds, an exclusive Wide Frequency Response tweeter with its own cabinet, and a cutting-edge slot-loaded port that permits placement close to rear walls are just a few of the audiophile-minded advantages that yield open, natural, and richly expressive sound.
Such prolific abilities from a sub-$1000 loudspeaker would've been unthinkable even a year ago. Not to mention such elegant aesthetics. More than eye-catching architecture, Diamond 11.3's sensually curved cabinets contribute to its "box-free" character and actively eliminate resonance. Ditto the internal bracing & fiber-lined walls. Able to play without unwanted colorations and detrimental vibrations, Diamond 11.3 is a champion of textures, tones, and transients. Its pedigree reaches all the way to the use of over-sized ceramic magnets rather than traditional neodymium in the tweeter, which produce smoother sonics and lend to pure, gorgeously rendered high frequencies.
"It delivers music in a tangible, coherent way with fine drive and rhythmic integrity. And although subtlety is an undoubted strong suit, it isn't achieved at the expense of scale and body. Also exceptional for what is essentially a budget speaker is the way it backs up these qualities with poise and control that's seldom found wanting..."

Clarity, Expression, Openness: Advanced Midrange & Bass Drivers
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, & 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.
Designed for Brilliance: Wide Frequency Response Tweeter
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 800Hz, 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 & smooth, pure, richly defined high-frequency detail.
More Than Just a Pretty Face: Curved Cabinets
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.
Bass Fundamentals: 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 and 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.
