Wharfedale’s Diamond speakers have served as the classic entry point to true high-fidelity sound, their exceptional value for money earning numerous ‘product of the year’ awards around the world. Free shipping ( to Continental US only! )
Outside-the-box thinking translates into outside-the-box sound from the Wharfedale Diamond 11.5 tower loudspeakers. Curved for your pleasure, the largest and mightiest entry in the Diamond 11 Series pull no punches when it comes to immersive performance and price-beguiling technology. The three-way floor-standers arrive ready to fill even the largest spaces with powerful, emotionally arresting sound by way of two 8" Kevlar woofers, a five-inch Kevlar midrange driver, and one 1" textile-dome tweeter. With Diamond 11.5, you don't just hear music. You feel it, picture it, and become part of it. Proudly building on a heritage that began nearly four decades ago with the original Diamond Series, Diamond 11.5 is built from the inside-out to stand out as the greatest value in its price class and provide a scope of audiophile faculties – detail, openness, expressiveness, smoothness, balance, realism – independent of genre preference.
Offering a freedom of placement that extends to being able to positioned close to rear walls, Diamond 11.5 excels when it comes to playback fundamentals. The natural decay of an extended note, the tautness and depth of realistic bass, the separation between instruments, the textures of a delicate voice, the energy of a climax, the tension of a slow-built passage: All the specifics that often mean the difference between accurate, spellbinding sonics and a faint, two-dimensional duplication of what happened in a studio or on a stage. To paraphrase a golden-age Eric B. & Rakim track, Diamond 11.5 has soul. And you'll experience it every time it's put to use.
Diamond 11.5's proficiency owes to both its elegant contours ( in addition to impressive looks, they defeat colorations and resonance ) and the array of sophisticated materials, drivers, and components within its 44.3" x 11.4" x 13.8" frame. Explore the engineering and construction in-depth below, & know that an updated version of Wharfedale's Slot-Loaded Distribution Port as well as the Wide Frequency Response tweeter – complete with its own cabinet, are exclusive to Diamond Series & pay aural dividends in the form of clarity, precision, and faithful-to-the-source information.
Highly Advanced Drive Unit Systems Provide Overachieving Performance
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.
Wide Frequency Response Tweeter with Over-Sized Ceramic Magnet
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.
Look at the Curves, Hear What They Do
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.
Natural, Taut Bass Via Slot-Loaded Distributed Port Design
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 (& 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.
