Wharfedale E20 (2012)

The Wharfedale E20 is a compact bookshelf loudspeaker introduced in 2012 as part of Wharfedale's E Series. It is not a vintage model in the traditional sense, but it draws on Wharfedale's long British loudspeaker heritage and its reputation for transparent, musical speakers at accessible prices. It sits at the entry-level to mid-tier part of the range. It was built for listeners who want a balanced sound for stereo music and for a home theater setup.

Design and Build Quality

The E20 has a clean, minimalist look. The cabinet measures 300 mm high, 180 mm wide and 260 mm deep, so it fits on bookshelves, stands or in smaller living spaces. It weighs 5.8 kg. The enclosure is medium-density fiberboard (MDF) with internal bracing to reduce resonances and panel vibrations. The stiffer box means less coloration from cabinet flex.

The front baffle is gently curved. That helps reduce diffraction effects - sound wave distortions caused by sharp edges - which can smear the stereo image. Finishes include high-gloss black, satin white and rosewood vinyl wrap. The magnetic grilles are fabric-covered and easy to remove, so you can run the speaker covered or with the drivers exposed.

Driver Technology and Acoustic Engineering

The E20 uses two custom-designed drivers. The 130 mm (5.25 inch) mid/bass driver has a woven Kevlar cone, a material prized in high-end audio for its strength, rigidity and damping. Kevlar resists deformation under pressure, so the cone moves accurately and stays linear at higher volumes. That gives tight, controlled bass and a clear midrange, which matters for vocals and instrumental timbre.

The tweeter is a 25 mm (1 inch) soft dome made from textile material. Soft domes are known for a smooth, non-fatiguing high-frequency response, without the harshness sometimes heard from metal domes. It sits in a shallow waveguide that improves dispersion and gives a wider, more consistent sweet spot across the listening area. That helps in awkward rooms where the listener is not seated directly on-axis.

The crossover is set at 2.8 kHz. Wharfedale engineers paid particular attention to phase coherence and driver alignment, minimizing time delays between the two frequency bands. The aim is a cohesive soundstage where instruments and voices are precisely located in space.

Bass Reflex Design and Placement Flexibility

The E20 is a bass reflex design with a rear-firing port. The port lets the rear wave of the woofer reinforce the lower midrange and upper bass. Frequency response extends down to 55 Hz, which is good for a speaker this size. It won't reproduce the deepest sub-bass without help, but it delivers a full, articulate low end, especially with a subwoofer in a home theater system.

The rear port needs some thought during placement. Wharfedale recommends keeping the speaker at least 5-10 cm away from the wall to prevent port blockage and bass buildup. Even so, the E20 is fairly forgiving compared to more sensitive models, and it works both free-standing and near a wall.

Performance and Sound Characteristics

Sensitivity is 87 dB and nominal impedance is 8 ohms, so the E20 is easy to drive. It pairs with a wide range of amplifiers, from budget AV receivers to higher-end integrated amps. It handles up to 100 watts, which leaves headroom for dynamic passages without distortion.

The E20 has a balanced, natural sound. The midrange is clear and detailed, which suits vocal-centric genres like jazz, acoustic and classic rock. The treble is smooth and extended without being overly bright, so it is easy to listen to for long sessions. Bass is tight and well controlled, with good articulation in the lower registers. Percussion and electric bass lines stay distinct and rhythmic.

Stereo imaging is a strong point. The E20 throws a wide, stable soundstage, with instruments placed accurately in three-dimensional space. Set up correctly, ideally in an equilateral triangle with the listening position, the speakers give a convincing sense of depth and separation.

Position in the Wharfedale Lineup

The E20 belonged to a broader E Series that included larger models like the E30 and E40, plus a dedicated center channel and subwoofer for full 5.1 surround configurations. The series was succeeded by the Diamond 200 series and later the Evo series. The E20 is still respected among users who like its British tuning, solid build and musicality.

Legacy and User Reception

The E20 is not as widely discussed as some of Wharfedale's flagship models, but it has kept a loyal following. Audiophiles and casual listeners alike praise its ability to outperform its price point, with a mature, refined sound for its compact size. It is often recommended for small to medium-sized rooms, desktop setups or secondary systems where space is limited.

Used units can still be found in good condition, and many continue to serve as reliable monitors in home studios or as part of compact hi-fi systems. Its combination of Kevlar drivers, thoughtful crossover design, and elegant aesthetics ensures that the Wharfedale E20 remains a relevant and respected speaker nearly a decade after its release.

The Wharfedale E20 is a well-engineered bookshelf speaker with a balanced sound, suited to music, movies or mixed media.
