Wilson Benesch Omnium – Ultra High-End Class Acoustics Listening Test

Extra-class floorstanding acoustic systems, Wilson Benesch Omnium – the culmination of 30 years of development experience from the famous British company. The model was created in collaboration after long and thorough research work of the SSUCHY project. The second from the top in the company's range, loudspeakers embodied the most advanced, bold and new sound solutions.

Design

Wilson Benesch Omnium amazes in a good way – everything here is made according to the excess principle and “for centuries”. For example, the support system is turned from a 120-kilogram aluminum billet and lightened in the process to 30 kg. The cabinet itself, made using A.C.T. 3Zero Monocoque technology, is made of biocomposite (Advanced Biocomposite Monocoque Technology, Poly-Alloy, Hybridised Construction), has a steel frame made of 13 mm elements inside and has maximum rigidity. It was the work in the pan-European SSUCHY project that allowed us to create a unique material from hybrid natural fibers and bio-based polymers - it provided an order of magnitude better damping than the previous version of carbon fiber cases. But the upper part of the loudspeakers is made of composite carbon fiber of an extremely complex profile - it dissipates reflected energy and levels out standing waves in the listening room.

The speaker system is 2.5 bands. The sensitivity of Wilson Benesch Omnium reaches 89 dB with an impedance of 4.5 Ohms, and the frequency response is in the range from 27 to 30,000 Hz with an error of 2 dB. One speaker weighs 140 kg with a height of 1,740 mm.

The 25 mm Semisphere tweeter, which was previously used in the company's speakers, has been significantly modified - and now there is a Fibonacci tweeter. Its dome also uses a geometrically optimized carbon fiber / nylon composite structure. The structure of the system was inspired by sacred geometry, hence the name. The driver with a patented neodymium magnet is mechanically decoupled from the body and guarantees wide dispersion in the absence of structural resonances. 

Technologies

The main drivers of Wilson Benesch Omnium use the characteristic Fibonacci Element caps. Made of carbon fiber / nylon elements of a complex three-dimensional shape, they guarantee both an improved frequency response and a noticeable reduction in distortion. The diffusers themselves are no less interesting; their diaphragms are made of Isotactic Polypropylene. This material has high rigidity and works perfectly with sound energy - so if a crossover is used in the speakers themselves, then only for bass and high frequencies. The midrange 170 mm Tactic 3.0 drivers are directly connected to the amplifier without a crossover, which eliminates phase distortion and achieves incredible sound realism.

In total, two 170 mm Wilson Benesch Tactic 3.0 woofers work for the upper bass, one similar woofer for the lower bass and two paired isobaric assemblies (2 x 170mm Wilson Benesch Tactic in Clamshell Formation) again for lower bass. The company's favorite Isobaric Drive System scheme significantly extends the length of the bass - in it, the woofers are connected in such a way that the rear driver provides the front driver with constant pressure behind its diffuser. As a result, the bass is very fast and tight.

The crossovers for the isobaric system are First-Order 500Hz Low Pass Filter, for the rest of the bass - First-Order, for the midrange frequencies, as already mentioned, a crossover is not used (the Directly Amplifier Coupled scheme is implemented). And only the tweeter uses a Second-Order crossover with a 5kHz High Pass Filter. No less interesting acoustic design - all bass and midrange drivers work in the Infinite Baffle Sealed Enclosure scheme, and the tweeter - in a closed box Labyrinth Sealed Tweeter Backplate.

Listening

Wilson Benesch Omnium, without a doubt, became the "highlight of the season" at the High End Munich 2025 exhibition. I didn't want to leave the listening room, and I wanted to start each new day by "calibrating" my perception with these loudspeakers. The enchanting ability of Wilson Benesch Omnium to reveal the true soul of music to the listener turned working with the loudspeakers into a real pleasure, which is characteristic not just of very good or even one of the best audio equipment. But of a true industry standard - regardless of the price category.

Wilson Benesch Omnium acoustic systems perfectly cope with any genre - their complete genre indifference allows you to easily dive into rock ballads, move on to complex electronic music, and then amaze with hyperrealism on the most difficult classical pieces. The grand piano literally materializes in the hall, and a large symphony orchestra breathes and forms a percussion fortissimo, indistinguishable from a real performance.

The reference depth of black and the phenomenal sense of rhythm draw you into listening like a whirlpool - the melodies change, time loses its meaning, and familiar compositions come to life with new emotions and colors. The beauty of the sound is especially strong here - the plasticity and fluidity of the delivery envelops and makes you feel the music not with your ears, but with your subconscious. The bass is dry and super-fast, has a huge length and excellent texture. The midrange is soulful and precise, the high frequencies never prevail, but amaze with detail. Bravo.

Conclusions

Wilson Benesch Omnium are reference acoustic systems, the industry standard in the field of Ultra High-End. We did not find any reason for criticism - everything is great here.
