Diamond 12.3 Floorstanding Speakers

$1,189.99 $1,699.99

The Diamond 12.3 is a slim 2.5-way floorstanding speaker for medium to large rooms — a full-range tower that needs no subwoofer for most music. Twin 130 mm (5") woven-cone drivers and a 25 mm textile-dome tweeter deliver a room-filling sound with a 40 Hz bass extension.

The 2.5-way bass-reflex design uses its two drivers to balance bass output and midrange clarity, crossing over at 2.2 kHz for a 45 Hz – 20 kHz response and a 102 dB peak SPL. At 89 dB sensitivity and 8 Ω (5 Ω minimum), it suits amplifiers from 30 to 150 W.

It is the compact floorstander of the Diamond 12 Series, sitting just below the larger 12.4. See it alongside our other floorstanding speakers.

Wharfedale Australia is the official, AVR-authorised distributor — every Diamond 12.3 is backed by genuine Australian warranty and local support.

GIVING YOU GOOSEBUMPS

Goosebump-inducing audio has long been relegated to only the fattest wallets. But not anymore. Thanks to intelligent design aided by the advancements of modern computer simulation, it’s the music through Diamond 12 that’ll leave you speechless, not its price.

COSTLY? FINK AGAIN.

Collaboration with one of the most successful loudspeaker designers on the planet, Karl-Heinz Fink, has helped produce Wharfedale’s most impressive Diamond series to date, and your all-access pass to the exclusive world of refined audio engineering.

ITS MUSIC FULL THROTTLE

These 2.5-way floorstanding loudspeakers feature 25mm textile dome tweeters and 2 x 130mm advanced PP cone drivers. The seperate bass and midrange drivers, combined with its large chassis size, make Diamond 12.3 perfect for medium to large sized listening spaces.

PUTTING YOU IN HARMONY

Precision-made magnet systems incorporate aluminium compensation rings to cull distortion and discordant tones caused by intermodulation. Wharfedale’s most advanced Diamond motor system ever built now puts you in perfect harmony with your music.

WE CALL IT ‘KLARITY’

A new formulated blend of polypropylene and mica significantly reduce flex to create a rigid, lightweight cone with low colouration and lightning-fast response. So, your new Diamond’s play harder, handle more power, and perform flawlessly, every time.

DIVE IN TO YOUR MUSIC

Dome tweeters incorporate woven polyester film and high-loss coatings to generate silky smooth high-frequency extension. And with driver systems optimised for wide dispersion, vocals, woodwinds, and strings sections ripple out, wall-to-wall, bathing you in sound.

DETAIL WITH A SIDE OF RIBS

New drive cones include custom-engineered ribbing combined with a low-damping surround. This increases cone rigidity and reduces colouration, giving you a more dynamic, more detailed listening experience – one that honours (not colours) your favourite recordings.

CROSSOVER TO HIGH-END AUDIO

Air core inductors, typically found in the most expensive loudspeakers, produce the lowest distortion of all inductor types. Combined with acoustic LKR 24db crossover topology, it creates incredibly fast, clean bass response. It’s high-end thinking for low-frequency brilliance.

INTELLIGENT SPOT BRACING

Computer simulated design intelligently braces opposing cabinet walls using specific wood composites to create Diamond’s most effective reduction in cabinet resonance. So your favourite recordings shine in vibrant technicolour, not the colour of your speaker cabinets.

HEARING YOU LOUD & CLEAR

Voice coils are wound on high-power epoxy/glass fibre bobbins seen only in the most expensive loudspeaker models. The reduced distortion and increased power handling means you can go loud, real loud, and still enjoy incredible clarity.
