Wharfedale EVO 4.S Centre Speaker

There are many evolutions in a lifetime of quality listening; we want to be there for all of yours. Borrowing from the very best of our flagship model Elysian, we built for you a premium step-up series packing more technology and more performance per square inch than any other speaker in its category. We were there for your first high-fidelity experience with models like Diamond & D300. Now we’re here for the next evolution in your home theatre journey thanks to EVO4.

Manufacturers Details: 

Upgrading On Your Terms

Our AMT (Air Motion Transformer) technology is a radical direction in high frequency reproduction. Not only musical with naturally low distortion, it’s also an efficient way of moving air. So no need to upgrade that amp. 

Looking Good, Sounds Great

Our radiused edges, unique chamber design and multi-layer sandwich construction absorbs energy, inhibits leakage and perfectly integrates with your room’s acoustics. Because a speaker’s look and its sound should take your breath away. 

Bigger Sweet Spot. Sweet!

AMT technology combines with a specially damped and vented soft-fabric midrange dome to create wide dispersion with a linear response from 800Hz to 5kHz, so you get great detail anywhere in the room.

Sit Them Anywhere

Our most advanced slot-loading technology ever (PLSP) equalises high internal cabinet pressure to low room pressure when venting bass energy. Because you want beautiful music no matter where you sit your speakers. 


EVO4.S is a 3-way surround speaker featuring  2 x 30*60mm AMT treble driver, 2 x 50mm soft-fabric midrange cone driver and a 150mm black woven kevlar cone driver. With a chassis size of 245 x 400 x 145+10-mm, EVO4.S is perfect for medium to large-sized home theatre spaces. Ensure the ground pound of a T-Rex chasing Jeff Goldblum through Jurassic Park shakes the ice cubes in your G&T, and never spend a fortune on choc tops at the cinema again thanks to the dynamic impact of EVO4.S. It’s your next evolution in home theatre listening and it’s available today.

Engineered With Care:

The Dawn of a New Standard

Wharfedale’s new EVO4 has grown out of the extensive research and development that produced the ELYSIAN flagship loudspeakers and borrows much of the technology involved in ELYSIAN. Primary focus is on the AMT development resulting in a radically different way of reproducing high frequency detail efficiently and accurately. Similar cabinet technology to ELYSIAN provides a stable and solid foundation for the drive units with radiused edges to help integrate the driver output with the room acoustics. In addition the unique SLPP bass reflex system, as developed for ELYSIAN, is now incorporated in EVO4. 

Key Features:


Developed from the advanced AMT in ELYSIAN, EVO4’s Air Motion Transformer treble unit utilizes a radically different way of moving air compared to the conventional dome tweeter. A large, pleated lightweight diaphragm is driven across its surface by rows of strategically placed magnets. Not only is this an efficient way of moving air but it is also very accurate as the diaphragm is under close control of the motor system at all times. The result is a wide bandwidth transducer that achieves low distortion naturally and delivers wonderful musical detail.

EVO4 Dome Midrange

To match to the EVO4 AMT, Wharfedale has developed a fast and responsive dome midrange with wide bandwidth thanks to the incorporation of a damped rear chamber. This soft fabric dome, damped with a plasticizer coating, is vented aperiodically into a specially shaped rear chamber that is profiled to scatter and absorb rear energy from the dome. As a result this dome midrange features a linear response from 800Hz to 5kHz, an astonishing bandwidth from such a unit. Thanks to its high flux magnet, the EVO4 midrange dome also has a high efficiency, ideally matched to that of the AMT, enabling it to respond easily and quickly to the dynamics of the music fed to it. The wide dispersion of this dome and AMT combination ensures that you’ll hear all the musical detail no matter where you sit.

EVO4 Bass

Utilizing the advanced, low distortion motor system developed for the ELYSIAN bass units, EVO4 marries this to a woven Kevlar cone fitted with a low loss rubber surround, giving a wide bandwidth driver which is equally adept at producing powerful bass in addition to a natural lower midrange quality. Like ELYSIAN, the bass units are loaded by the most advanced version of the unique Wharfedale Slot Port yet. Christened SLPP (Slot Loaded Profiled Port) the rear output of the bass units is not wasted. Instead the lowest frequency energy is vented to a slot at the base of the speaker, specially profiled to equalize the high internal pressure to the low pressure in the room.

EVO4 Crossover

Combining the outputs of the drivers is an advanced computer modeled crossover that has been developed over hundreds of hours of listening tests, fine tuned to make sure that the blend between the drive units is seamless. Crossover components have been specially chosen for their audio transparency and feature high-grade polypropylene capacitors and laminated silicon-iron and air core inductors, laid out to avoid electro-magnetic interference on a specially designed circuit board.
