Overview

Our take on the Wharfedale Diamond 225

Meet the Diamond 225s, the top model in Wharfedale's Diamond 200 Series of bookshelf speakers. These high-performance speakers offer robut full-range sound with punchy bass and crisp, clear highs — especially when paired with a high-current amplifier. 

Sparkling musical performance

Meet the Diamond 225s, the top model in Wharfedale's Diamond 200 Series of bookshelf speakers. These high-performance speakers offer robut full-range sound with punchy bass and crisp, clear highs — especially when paired with a high-current amplifier. 

High-quality drivers for music and movies

Each Diamond 225 speaker packs a powerful sonic punch. A 6-1/2" woven Kevlar® woofer complements a 1" soft dome tweeter, creating rich, full sound. They're ideal for the front or surround channels of a Wharfedale home theater system.

These speakers are also an excellent choice for a stereo music system. If you have a big room or want even deeper bass, consider adding a powered subwoofer to extend low-end performance. 

Praise from Stereophile


"Forget the Diamond's modest price. This humble wooden box is actually a connoisseur-level audio component. It could satisfy any sane music collector for decades”

— Herb Reichert, Stereophile March 2017

Wharfedale Diamond 225 Bookshelf speakers

The Wharfedale Diamond 225 bookshelf speakers feature two pairs of input terminals for bi-amping or bi-wiring.

Solid construction

Wharfedale paid special attention to the design of the 225s' speaker enclosures. They used advanced computer modeling to craft non-resonant cabinets with stiff walls and internal bracing. A slot-loaded port reinforces bass performance.

Bi-amp or bi-wire for even better sound

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

Sophisticated, sleek, artistic looking speakers!!!

Crutchfield Customer Review (What's this?)

Very Nice product. Everything I had expected and them some. These speakers were well built. Nice looking and contemporary feel to them.

Pros: Nice contemporary design. Sophisticated look. The SANUS speaker stands complement the sleek sophisticated look and design of the WHarfdale speakers, Low profile speaker stands are nice to have with plenty of power so it seems. Smooth Highs on French horn sounds coming through speakers. Especially on Classical music (specifically)

Cons: I had bought these speakers to bi amp with another Sony amplifier. They do not work that well with the BI AMP able capaballities??? I don't quite understand why the two amps to not complement each other while powering the new Wharfdale speakers??? The back of the speakers are NOT very easy to hide the speaker wires down the back of the SANUS Speaker stands The 18 " stands. I still have NOT FIGURED OUT HOW TO utilize the Sony Walkman yet, as far as uploading music to the SONY Walkman???

Crutchfield Customer Review (What's this?)

Because the Diamond 225--which is an audiophile-grade speaker (see Stereophile's Product of the Year Awards for 2017)--works so well as a near-field monitor, I use it at my computer station, driven by a Sony ES receiver (STR-DA5ES), but I originally tested it (on stands) next to KEF LS50 and DALI Mentor 6 speakers, where the 225 held its own, in both depth and articulacy, while powered by an NAD M27 amplifier (pre-amped by a Marantz AV8802a). I play all sorts of music, from punk to classical, and this speaker keeps up beautifully. Horns in Grieg's "Peer Gynt" are saturated with all their harmonics (not just "clear"). Drums in "Head Over Heels" (by Tears for Fears) are controlled but resonant. In Bach's Mass in B minor, voices spring to life without blaring. And Miles Davis never had it so good in this lazy, wistful corner of the room. The KEF LS50 is probably one level up in finesse, but, at a fraction of the price, the Diamond 225 is one of those purchases that, when you look back at it, you can say, with confidence, "that's a best buy"--and I mean "Crutchfield" when I say that!

Pros: Quality of sound. Price.

Cons:

Wharfedale does it again!

Crutchfield Customer Review (What's this?)

I've had wharfedale speakers in the past and so I'm quite familiar with the brand. I saw these at Crutchfield on sale and I decided to take the leap of faith on these speakers. First off the speakers arrived in 2 days not 3 days which was awesome. After unboxing the speakers I noticed what a gorgeous finish they had not some cheap vinyl wrap. After hooking them up to my tube amp I started to listen to some music from my satellite TV. I was immediately Blown Away how clean the speakers sounded. All speakers need to go through a burn in. What is scary is how much better the speakers will sound after the burn in. Since my tube amp has no adjustments for bass treble or mid-range it runs basically pretty flat. But the speakers sound so natural and clear that I really don't need to tweak anything. The treble is clear but not irritating. Mid-range is acceptable but what really makes the speaker great is the bass. It is a down-firing port and it's not overpowering when you turn up the volume. Just enough bass for flavor. There is a little space between the bottom of the speaker and the speaker plate allowing for the air to leave. I placed these speakers on 24 in stands and used 14 gauge speaker wire as a hookup. The black piano finish on the front and unique grills really set these bookshelf speakers apart from any speakers that I've owned in the past. I'm not using it as a surround sound speaker. Mainly for listening to music and bypassing the lousy small speakers on my flat screen.

Features

2-Way Driver Design: The Wharfedale Diamond 225 is a 2-way bookshelf loudspeaker which incorporates a 1" fabric soft-dome tweeter and 6.5" woven kevlar cone woofer. A finely tuned crossover guarantees a smooth transition between the tweeter and woofer 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.
  • 6.5" Woofer: Semi-elliptical "break-up" areas on the 6.5" woven-kevlar woofer 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 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: Each bookshelf 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 speakers provide 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.

Mounting Options: These bookshelf loudspeakers can simply be mounted on stands, shelves, or other piece of AV furniture with a flat surface. Eight self-adhesive rubber feet (4 for each speaker) are included to protect the bottom of the speaker and the mounting surface, while isolating the speaker cabinets from the mounting surface. The rubber feet add approximately 0.375" to the overall height of the speakers.

Note: The speakers do not include any type of wall-mount bracket, keyhole slot, or threaded insert.

Placement: Try to position the loudspeakers equidistant (6.5' to 13') from one another and the main listening position. The speakers should ideally be positioned so that the tweeters are roughly at ear level to a seated listener. 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.
