One of the leading brands in the HiFi industry, Wharfedale has produced some excellent speakers in the past decades. The Diamond series of loudspeakers is one of the most outstanding offerings from the brand, launched in 1981. Each new series of Diamond takes the most powerful features from the previous generations and adds improvements to offer more in terms of performance and cost.
In this post, we review the Diamond 11.2 loudspeaker and take a closer look at its features, specifications, performance, and other details to help readers understand what they can expect from this product.
Wharfedale Diamond 11.2 Review – UPDATED 2021
According to the company, the Diamond 11 series gives a chance to start afresh by wrapping all the design and performance features from the earlier versions into a single redesigned package. The aim of the brand with this generation of loudspeakers is to offer affordable pieces while building from the ground up keeping performance at the forefront.
Wharfedale is a British brand that carries out its research and development in the United Kingdom but is acquired by a Chinese company, the IAG Group which also owns Quad, Audiolab, Luxman, Castle Acoustics, and Mission.
The Diamond 11.2 is the biggest of the three bookshelf speakers in the newly introduced range of eight models in the series, including two center channels and three floor-standing models. This speaker is an extension of the Diamond 11 series that adds to the home cinema experience when added to a surround sound system.
The Diamond 11.2 contains a 1-inch fabric-dome tweeter and a 6.5-inch mid/woofer inside a fiber-filled, MDF cabinet. The company puts a lot of effort into driver construction. The bass and midrange driver consists of a woven Kevlar cone woofer and uses a basket with a rib network to maintain rigidity while leaving an open space behind the cone to reduce reflections and let the internal cabinet function properly.
The speaker height is 14-inches but it is wider and deeper than the previous versions. The tweeter is mounted at the center of the waveguide to control dispersion but has a specially shaped rear chamber for precise sound. The sidewalls of the enclosure are curved at the back to reduce resonance while the slot acting as a reflex port extends across the width and depth but has curves at the entry and exit for linear airflow.
Despite the affordable price, the Diamond 11.2 features an attractive glossy black front. Electrical connection occurs through a pair of binding posts on the rear of the cabinet. Both tweeter and woofer have a copper-cap plate known to linearize magnetic flux and reduce inductance.

Textile Dome Tweeter
The new bookshelf speaker is capable of delivering improved high-frequency performance with the evolved tweeter design. The textile dome tweeter comes with a large ceramic magnet system featuring a copper cap and vented pole plate to guarantee low resonance and high linearity for a precise sound at high frequencies. The low-profile waveguide around the tweeter offers wider dispersion of these frequencies.
The Diamond 11.2 speakers pack a punch with carefully constructed drivers. The 6.5-inch woven Kevlar woofer complements the 1-inch soft dome tweeter to provide a fuller, richer sound.
For the Diamond 11 series, Wharfedale has refined the cabinet construction further with curved walls that give a less boxy shape. This helps reduce unwanted colorations from internal resonance and panel vibrations to allow more musical detail.
The rear-panel distribution port is slot-loaded to reduce noise associated with average ported systems. This innovative design gives a more linear airflow through the port for smoother performance.
To design the cabinet for the Wharfedale Diamond 11 series, the engineers have refined multiple layers of woods with varying density to subdue cabinet sound characteristics, allowing the drivers to show their performance. The cabinet walls are further lined with special internal fiber known for its absorbent qualities across a wide bandwidth.
Fine-Tuned Crossover Components
The company considers a highly evolved crossover system to create a series of circuit options with a combination of bass/midrange and treble drivers. These are then evaluated with the help of listening tests over a period of time across a variety of music. When a circuit is finalized, it is fine-tuned for components to give the most enjoyable and accurate sound performance.
The bookshelf speaker features an acoustically transparent cloth grille that attaches with magnets to the front of the cabinet.
The Diamond 11.2 loudspeaker can be mounted on stands, shelves, or any rigid surface. It comes with self-adhesive rubber feet to protect the bottom and the mounting surface and to add some height.
Wharfedale Diamond 11.2 Test
When listening to the loudspeaker as a part of a home theatre system, you can then realized its true talent lies in its insightful midrange. The voice comes out textured beyond what other models could produce and there is a graininess to the guitar that other speakers might sound clean.
There is no denying that the Diamond 11.2 offers a lot of low-end frequencies as well. It is rare that such a small loudspeaker can produce such hefty bass even at a moderate volume. The frequencies take over the mix and the sense of timing and dynamics is a bit loose, giving a colder feeling than listening to the same tracks on some other speakers.
Playing a piece of music like ‘A Midsummer Night’s Dream’, the Diamond 11.2 provides a warm and rich sound, with a sweep of the orchestra. Violins sound perfect without being harsh, the lower strings show the right body and the soundstage is wide and deep. The piano sounds convincing and sweet as well.
The Wharfedale Diamond 11.2 bookshelf loudspeaker is a great choice for 2 channel stereo music as well as multichannel home theatre applications. To use it in a two-channel application, position them at equal distances from each other and the listening position. Place the speakers in such a way that tweeters are at ear level to the listener.
The Diamond 11.2 speaker also works as a front or surround speaker in a home theatre system. Position the speakers at equal distances on either side of the screen at ear level and angle them slightly towards the listening position for using them as front speakers. When using them as surround speakers, they should be positioned higher behind the listening position. If the side or rear walls are too far from the listening position, consider stand-mounting the loudspeakers.
Wharfedale Diamond 11.2 Vs 225 – How They Compare?
Both Diamond 11.2 and Diamond 225 are bookshelf speakers from Wharfedale that are similar in several ways, but also have some differences. Both these models are 2-way speakers featuring a 1″ soft-dome tweeter and 6.5″ woven Kevlar woofer. The frequency range of the two speakers is also quite similar.
The two models have the same impedance of 8 ohms but they differ in terms of sensitivity levels. A difference of 1dB in speaker sensitivity makes the Diamond 11.2 a little more sensitive as compared to the 225, being able to play louder with the same power. Another difference lies in the bi-wiring feature. The Diamond 225 comes with Post to allow bi-wiring whereas the 11.2 model has two posts that don’t support bi-wiring.
Overall, the two speakers from the Diamond series are affordable options for bookshelf models. In terms of value, the 11.2 performs on par with the 225. For a small to medium listening room, both the models deliver satisfactory performance over a wide range of music styles, sounding simple and decent.
The Diamond 11 series from Wharfedale is a popular line that serves as a classic entry point to high-fidelity sound with lifelike sound and natural instrument sound reproduction. It is an ideal choice for those who want an outstanding HiFi performance without breaking the bank. The Diamond 11.2 bookshelf loudspeaker, with all the features from the previous generations combined with the latest advancements, makes an excellent addition to a beautiful-sounding home theatre system.
