4-Way Floorstanding 12" Dual Concentric HiFi Loudspeaker (Gloss Walnut)

The Kingdom Royal is a new flagship loudspeaker representing the sum of Tannoy’s rich heritage, cutting-edge technical innovation and world renowned acoustic engineering.

 A true no-compromise design, Kingdom Royal brings together a new series of Tannoy reference components, a radical new cabinet and the finest quality materials throughout. From the high gloss wood veneer and Italian leather trim to the all-new 12in Dual Concentric™ driver with its cryogenically treated 3in HF dome and compression motor, every component represents the pinnacle of materials, technology and the summit of Tannoy’s technical excellence.

The result is a triumphant expression of Tannoy itself. Pushing the boundaries of high-end loudspeaker design to new levels, Kingdom Royal offers unsurpassed acoustic performance, ultra-low colouration, high efficiency and musical integrity unmatched by any other loudspeaker on the market today.

After four years of extensive research and development, Kingdom Royal brings a wealth of new features and new technologies to the loudspeaker market.

The Kingdom Royal cabinet delivers stunning visual form derived from its no compromise function. The massive curve-sided cabinet is constructed from machined high-density fibreboard and birch plywood sourced from cooler, slow growing regions of the world for its superior density and acoustic properties. Built with both vertically laminated sections (the inner fibre-loaded board) and horizontally laminated sections (the outer birch-ply hardwood) and braced with Tannoy’s DMT™ material, the cabinet is incredibly rigid despite the immense panel areas. This engineering technique has afforded a very stiff enclosure with high internal volume that allows the deepest bass notes to expand naturally into the room.

The sealed SuperTweeter™ enclosure is precision milled from a laminate of high density fibreboard and acoustically separated from the main cabinet enclosure. Tuned and damped by a long process of measurement and audition, the SuperTweeter’s performance is further enhanced by a soft dispersion panel set in front of the housing. After trialling a number of synthetic and natural materials, soft Italian leather was selected as the acoustic dispersion panel of choice.

The Kingdom Royal necessitated the largest crossover Tannoy has ever produced, being a double-decked design built on boards as wide as the cabinet interior. The entire crossover is decoupled from the cabinet base using an innovative free floating mounting system incorporating rubber suspension turrets and brass rods to separate the two layers. Both upper and lower boards are hardwired using silver-loaded solder and Acrolink’s six-nines copper (99.9999% pure copper) cable. The SuperTweeter™ circuit employs 99.997% purity single strand silver cable for its exceptional top end transparency. Tannoy’s DMT™ (Differential Materials Technology) compound is used to bed-in components, further improving damping and resulting in greater naturalness and pinpoint imaging. Each crossover uses the very latest ICW ClarityCap MR polypropylene capacitors, low loss laminated core inductors and non-inductive heat sink mounted thick film resistors. For impedance matching, the Dual Concentric™ HF unit uses a custom built autotransformer for greater clarity and top-end articulation than a traditional resistive circuit. Once assembled the entire double-deck crossover undergoes full deep cryogenic treatment to relieve component and conductor stresses at crystal level.

Tannoy has left no aspect of the Kingdom Royal unchallenged. Adjustments for the Dual Concentric’s Tweeter and SuperTweeter™ energy levels are available using a new low-loss switching panel mounted on the front baffle. For manoeuvring each speaker is supplied on castors but in the final listening position it is coupled to the floor using built in steel cones on the underside of the speaker that couple to substantial gold anodised aluminium feet. On the rear panel the finest WBT™ binding posts are configured in Tannoy’s unique five terminal design that affords Bi-Wiring or Bi-Amping as well as direct grounding (via the fifth terminal) for the chassis of the main drivers. Spare HF energy level control pins, spare SuperTweeter™ grille and six-nines pure copper bridging cables are supplied in a wooden presentation box.

This Kingdom Royal’s top class build quality is complimented with a sumptuous finish that mixes textures and colours in a very contemporary evolution of Tannoy’s Prestige loudspeaker range. Traditional wood veneer side panels are finished in contemporary deep gloss lacquer, while the smooth black satin finish baffle complements the gold trim and natural Italian leather. Subtle, sophisticated and classically good looking with the heavyweight weave cloth grille in place, yet bold, imposing and dynamic with the grilles removed, the Kingdom Royal is a speaker that spans stylistic genres with ease. Built in Tannoy’s UK factory to the very best engineering and quality standards, each Kingdom Royal loudspeaker weighs 120kg.
