The Evo 4.1 speakers are modelled on the technologies and concepts seen in Wharfedale's highly acclaimed Elysian speakers. Emphasising on incorporating Air Motion Transformer technology in the speakers, the Evo series offer a high quality sound with low distortion guaranteed. The AMT driver provides low distortion and enhanced dynamics. Designed for any taste

Slot-Loaded Distributed Port Design: The EVO 4.1 uses a slot-loaded distributed port design, wherein the internal gate tube opens in a slot that is formed between the speaker cabinet and the base. This reduces turbulence and audible "chuffing" of conventional gate systems, caused by the sudden burst of high-pressure air in low pressure in space. Another advantage is the increased efficiency of the energy transfer of the bass reflex tuning to the space. Both ends of the gate are provided with a semi-parabolic input and output curve that controls the air flow through the gate tube and allows a higher air volume into the system loaded with slots for a further improvement of the low-frequency output performance of the speaker. No guessing why when a range ends, that not every model gets discounted. A couple never sold as well and end up in Richer Sounds or Sevenoaks at 40% off.

Conclusions

The EVO4 line of Wharfedale uses technology and design elements that have been developed for the company's flagship, the Elysian line. The 4.1s are equipped with an advanced folded ribbon tasting that produces silky high frequencies, and a 5 "woven Kevlar Woofer offers a solid bass display. The drivers are housed in a few curved bas reflex cabinets that are carefully designed with internal reinforcements to dampen the vibrations. Low frequencies are handled by Wharfedale's low-distortion motor system, coupled with woven kevlar cones to deliver powerful bass you can both hear and feel. The strong, lightweight Kevlar makes the driver both fast and powerful, delivering accurate bass that can be impressively low and loud when desired. Most notably within the Wharfedale EVO 4 series is the newly incorporated Air Motion Transformer, a specially engineered tweeter that pushes the boundaries of conventional tweeter technology by moving higher amounts of air around, encouraging a silky-smooth high frequency performance. With this highly efficient technology only do you enjoy finer musical details, but resolution is greatly improved as well as dynamics, accuracy and distortion levels.

Bi-amping: With Bi-Amping you can use individual amplifiers for the high & low frequency sections of your speaker for a larger dynamic range & lower distortion. We recommend that your individual amplifiers have the same reinforcement to maintain the voice balance of the speaker. Placement

Wharfedale Evo 4.1 Speakers (Pair)

As for position, I have them on stands (spiked through carpet on concrete floor) just over a foot away from side walls and pretty much open from behind and slightly toed in towards listening position. I was mightily impressed with what I received for the money. I went with the white wood veneer version to fit in seemlessly with my IKEA furniture :) The build quality is reminescent of older generation B&W Nautilus 805 speakers(!). Yes, it’s that good. The MDF enclosure is well-damped and basically dead. On the rear end, you’ll find gold plated bi-wiring terminals. Everything feels premium about this little speaker. I also loved the magnetic dust covers. A slight disappointment is the cheapish metal bridge for the bi-wiring terminal. But hey, we’re talking about a 400 Euro bookshelf speaker here. The Wharfedale EVO4.1 Stands are purpose-designed for the Wharfedale EVO4.1 standmount (or bookshelf) loudspeakers.

Prices valid in stores (all including VAT) until close of business on 29th November 2023. (Some of these web prices are cheaper than in-store, so please mention that you've seen these offers online.)We have reasonable directivity for a while but then physics takes over and beam width narrows logarithmically with frequency (shown as a line here since horizontal axis is in log). Below that beam width is a bit larger than usual so the imaging would be more diffused around the speaker (good thing in small speakers in my opinion). I don't know if this is a dealbreaker but after reading this I kind of focused more on the Diamond 12.2. I wonder if the Evo 4.1 is still worth it Tying everything together is a fine sense of timing that results in surefooted rhythms and the ability to present a mass of instrumentation as a cohesive and musical whole. The longer we listen, the less we find ourselves analysing the sound, and the more we simply enjoy the results. AMT (Air Motion Transformer) Inverter: The Wharfedale EVO 4.1 Bookshelf speaker uses a specially designed 1,1875" x 2,375" AMT (Air Motion Transformer) transducer for his own silky high frequency reproduction. The design of the AMT makes it possible to move a higher air volume during implementation than with a conventional soft dome tid. This higher pressure, which is stimulated by the principles of the AMT design, offers improved HF display of point sources with lower deformation properties than conventional tweeters. This is reflected in the stunning and pure brightness of the musical performance of all EVO 4.1 bookshelf speakers. The highly advanced AMT (Air Motion Transformer) tweeter delivers class-leading detail and precision through its high-tech design. By squeezing the air between sound plates, the EVO 4.1 offers a highly consistent and precise top end that’s fast to respond to all types of music – making your favourite tunes sound more believable than ever.
