Our take on the Wharfedale Diamond 240

The Diamond 240 sits is the "sweet spot" of Wharfedale's Diamond 200 Series floor-standing speakers. It's the least expensive tower speaker in this line to employ a three-way design, distributing frequencies among two 6-1/2" woofers, a 5-1/8" midrange driver, and a 1" soft dome tweeter. Its neutral tone and strong bass response make it ideal for reproducing natural, lifelike sound in medium- to large-sized rooms.

Awesome for music and movies

Use a pair of Diamond 240s to anchor the front soundstage of a Wharfedale home theater system. This speaker is also equally impressive as part of a stereo music system, delivering dynamic sound throughout its frequency range.   

Solid construction

Wharfedale paid special attention to the design of the 240's enclosure. They used advanced computer modeling to craft a non-resonant cabinet with stiff walls and solid 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 240 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

Pair the 240 with other models from the Diamond 200 series for voice-matched sound:
Center channel: Diamond 220C or Diamond 240C
Bookshelf speakers: Diamond 210Diamond 220, or Diamond 225
Floor-standing speakers: Diamond 230 or Diamond 250

Great sounding speakers. The sound is very pleasing with no listening fatigue. They also look very nice in home decor.



Really like these

Crutchfield Customer Review (What's this?)

I REALLY like these speakers! I owned a nice set of 3-way speakers back in the 80's, but in the 90's I fell into the subwoofer/satellite craze and dwelled there for many years. I had some nice bookshelf speakers over the years (JBL, Polk, Klipsch, Infinity, Wharfdale) and enjoyed them all. Recently however, I started getting curious about floorstanding speakers again, with the advancements in technology and the tower designs that don't occupy any more floor space than bookshelf speakers on stands. I'm very glad I did! These towers look and sound great, and now I remember what I was missing from my 3-way speakers back in the 80's. I love the way each instrument and vocal comes through clearly, and the overall sound is so warm and balanced. I'm using them primarily for music but they are part of a home theater so they will get some use for movies as well (the matching center channel for these is also great). They do require some power to drive them. I'm using a Denon X4200W AVR (125 watts per channel). I have them bi-amped using 12-gauge wire and I'm loving the sound. Got these at Black Friday pricing and couldn't be happier.

Pros: Clear, detailed, and balanced sound Unique styling Big speaker sound in a small footprint Can get by without a subwoofer, for music at least

Cons: Power hungry

Product Research


3-Way Driver Design: The Wharfedale Diamond 240 is a 3-way floorstanding loudspeaker which incorporates a 1" fabric soft-dome tweeter, 5.125 woven kevlar midrange driver, and two 6.5" woven kevlar cone woofers. Finely tuned crossovers guarantee a smooth transition between the tweeter, midrange, and woofers with an enjoyable audible experience, both on and off-axis.

  • Fabric Soft-Dome 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.
  • Woven Kevlar Woofer Cones: Semi-elliptical "break-up" areas on the woven-kevlar woofer cones (including the 5.125" midrange & dual 6.5" woofers) 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 240 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.
