About the Wharfedale Diamond 230

Sparkling musical performance

Looking for outstanding value in a floor-standing speaker? You'll be hard-pressed to find better performance for the money than the Wharfedale Diamond 230. This is the smallest tower in the Diamond 200 Series, yet it offers robust full-range sound with tight bass and crisp highs — perfect for small- to medium-sized rooms. 

Sparkling musical performance

Looking for outstanding value in a floor-standing speaker? You'll be hard-pressed to find better performance for the money than the Wharfedale Diamond 230. This is the smallest tower in the Diamond 200 Series, yet it offers robust full-range sound with tight bass and crisp highs — perfect for small- to medium-sized rooms. 

High-quality drivers for music and movies

The Diamond 230 packs a powerful sonic punch. It features two 6-1/2" woven Kevlar® woofers — one for bass and another for midrange. The woofers are teamed with a 1" soft dome tweeter. Together these drivers create rich, full sound for music and movie soundtracks. 

Solid construction

Wharfedale paid special attention to the design of the 230's enclosure. They used advanced computer modeling to craft a non-resonant cabinet with stiff walls and internal bracing. A slot-loaded port on the underside of the tower reinforces bass performance.

Bi-amp or bi-wire for even better sound

On the back of the 230 you'll find two sets of speaker input terminals. These let you bi-amp or bi-wire your speaker to get the best sound out of it. 

Build a full system

Grab a pair of the 230s for a sweet-sounding stereo music system, or mix and match them with other models from the Diamond 200 Series for voice-matched surround sound:
Center channel: Diamond 220C or Diamond 240C
Bookshelf speakers: Diamond 210Diamond 220, or Diamond 225
Floor-standing speakers: Diamond 240 or Diamond 250

Product Research


2.5-Way Driver Design: The Wharfedale Diamond 230 is a 2.5-way floorstanding loudspeaker which incorporates a 1" fabric soft-dome tweeter and two 6.5" woven kevlar cone woofers. A finely tuned crossover guarantees a smooth transition between the tweeter and woofers with an enjoyable audible experience, both on and off-axis.

  • 1" Tweeter: The 1" tweeter uses a sheer fabric dome and advanced ferrite magnet system, surrounded by a carefully crafted wave guide that encourages outstanding midrange performance too.
  • Dual 6.5" Woofers:  Semi-elliptical "break-up" areas on the 6.5" woven-kevlar woofer cones smooth the response through the audible range. The cone edges are treated with a unique diamond pattern rubber surround.

Non-Resonant Cabinet: The speaker cabinet combines layers of particle board and MDF, bonded in a unique structure to damp annoying resonances and block internal sound leakage. The result is that the "noise" and distortion from cabinet walls are buried more than a 35dB below the driver output. Cabinet walls and internal bracing were developed using Wharfedale's latest "Virtual Speaker" software, with the help of Delayed Cumulative Spectral Analysis. The top, bottom, and side walls of the cabinets are finished with a wood veneer (black, rosewood, or walnut), while the baffle is finished with a gloss black lacquer.

Bass Port: Exiting the base of the speaker cabinet is a slot loaded distributed port created by the plinth. This equalizes the air pressure to mimic that inside the cabinet allowing a smooth transition between the pressure variation in the cabinet and the low frequency sound developed in the room.

Dual Binding Posts: The floorstanding loudspeaker has two sets of binding posts connected by jumper-plates. The binding posts will accept bare wire (up to 10AWG), pin connectors, spade connectors, & banana plugs (single only). Using these dual binding posts, you can bi-amp or bi-wire the speakers. Bi-wiring or bi-amping the speaker provides improved bass & treble performance. If you decide to bi-wire or bi-amp, you must remove the jumpers between the terminal posts (failure to do this could result in damage to your amplifier and loudspeakers).

  • Bi-Wiring: Bi-wiring can provide noticeable improvements in the overall transparency of your loudspeakers. Run separate speaker wires to the low & high frequency drivers from a single amplifier (the upper set of binding posts are for the high frequency drivers; the lower set of binding posts are for the low frequency drivers).
  • Bi-Amping: Bi-amping allows you to use separate amplifiers for the high & low frequency sections of your loudspeaker for greater dynamic range & lower distortion. We recommend that your separate amplifiers have identical gain to preserve the speaker's voicing balance.

Spike Feet & Isolation Pucks: The Wharfedale Diamond 230 floorstanding loudspeaker comes with four spike feet for carpet installation. Four isolation pucks with foam padding are also included to protect your hardwood, tile, laminate, and vinyl flooring. The spike feet screw into the bottom of the speaker cabinet's plinth and are adjustable so you can level up the speaker. The spike feet can be placed directly on carpet or set in the isolation pucks to protect hardwood, tile, and laminate, and vinyl flooring. The isolation pucks add approximately 0.25" to the overall height of the speaker.

Placement: Try to position the loudspeakers equidistant (6.5' to 13') from one another and the main listening position. The speakers should be "toed" or angled (15° to 40°) into the main listening position. The speakers can be positioned as close as 2.3125' to 3.3' from a side facing wall. There should be a distance of at least 0.6875' to 3.3' between the back of the speaker cabinets and the wall (the speakers' bass extension will improve if they are positioned closer to a wall or corner).

Diamond Series: The Wharfedale Diamond series consists of three floor-standing loudspeakers (Diamond 230 / Diamond 240 / Diamond 250), three bookshelf loudspeakers (Diamond 210 / Diamond 220 / Diamond 225), and two center-channel speakers (Diamond 220C / Diamond 240C) - all sold separately.

I have Denon X550BT. Does this AVR can supply enough power for this speakers with a full 5.1 setup?
[ AK Dutta  Aug 22, 2018 ]
1 answer
It appears you have a Denon model made for use in the UK. Regardless, it's rated output (70 watts per channel into 8 Ohms) falls well within the recommended range (between 25 & 150 watts) for the Diamond 230.
