Wilson Benesch Fibonacci Series - Endeavor 3Zero 2.5-Way Stand Mount Loudspeaker (pair)
A SUPER MONITOR.
AN AFFIRMATIONAL LISTENING EXPERIENCE.
Since its foundation, Wilson Benesch has invested heavily in ambitious research and development projects in the fields of materials science and manufacturing. The Endeavour 3Zero exploits more than three decades of work, to distil a multitude of cutting-edge Wilson Benesch technologies in its flagship standmount loudspeaker design.
The Endeavour 3Zero builds upon the Discovery 3Zero, adding additional air volume in a larger enclosure that adds more drive and composure to the larger of the two siblings.
Like the smaller Discovery 3Zero, the Endeavour 3Zero places the Fibonacci hybrid dome Tweeter directly at the acoustic centre of bass and midrange drivers. The sonic delivery is perfectly poised, tonally balanced, natural-sounding and seamlessly integrated. Listening to the Endeavour 3Zero is an affirmational experience.
Through expert design, craftsmanship, the deployment of advanced materials technology and geometrically optimised componentry, Wilson Benesch has created a stand mount loudspeaker design with no compromise. The Endeavour 3Zero faithfully reproduces the musical ensemble, as though the performers were there in the room before you.
DESIGN
TACTIC 3.0 DRIVE UNIT
The structure at the centre of the diaphragm plays a critical role in the behaviour of the drive unit. Commonly referred to as the “dust cap”, the name understates the importance of this component. In the Tactic 3.0, Wilson Benesch added the Fibonacci Element.
Produced in house using additive manufacturing technology, the Fibonacci Element can be printed according to pre-designed parameters. Such is the precision of the additive manufacturing software, that the Wilson Benesch design team can see in cross-section and design three-dimensionally the optimal layup of carbon fibre and nylon, defining both stiffness and weight across the structure. The result is a new geometrical form that is comprised of a double curvature with both open and closed aspects in the form of a lattice structure again borrowed from natural geometry. 5 different materials and adhesives provide significant improvements in both the accuracy of the frequency response and the reduction of distortion.
This is a critical aspect of the relationship between the drive unit and its ability to integrate with the roll off of the tweeter and bass drive units. In the past, several materials have been drawn upon to enable the fine-tuning of this marriage. Additive Manufacturing has opened up a new chapter in the pursuit of this subtle but extremely important aspect of loudspeaker design. For the first time, the principal aspects of this structure can all be adjusted in a way that was previously impossible.
FIBONACCI SILK-CARBON HYBRID TWEETER
The latest iteration of Wilson Benesch tweeter technology builds upon the Semisphere tweeter design pushing it into the next generation. As with all Wilson Benesch designs, the advances of the previous generation are built upon an iterative research and development pathway. With the Fibonacci tweeter, advances have been made within the structures adjacent to the motor and the hybridised dome. The Fibonacci tweeter faceplate is formed from a carbon fibre - nylon composite structure creating a geometrically optimised structure - the Fibonacci Element - that has been inspired by sacred geometry found in nature. In terms of acoustic performance, the faceplate delivers a new benchmark in terms of flat frequency response and ultrawide dispersion. In addition, the Fibonacci Element is decoupled from the motor and tweeter chassis which almost entirely eliminates structural borne resonance within this critical structure that surrounds the tweeter dome.
A.C.T. 3ZERO BIOCOMPOSITE MONOCOQUE
The Fibonacci Series introduces a full line of loudspeakers from the Wilson Benesch brand that are built from the new A.C.T. 3Zero biocomposite Monocoque. The new monocoque marks significant advances not only in terms of the acoustic performance of the Wilson Benesch reference line, but it also represents a deliberate and conscious move toward natural, renewable and sustainable materials technology.
ISOBARIC DRIVE SYSTEM
The principal low-frequency load of all loudspeakers in the Fibonacci Series is delivered by the Isobaric Drive System. Here two Tactic 3.0 Drive Units combine to create an Isobaric Drive System. The Isotactic Drive System is responsible for reproducing an incredibly tight and controlled bass response that is perfectly integrated with all other woofers in the loudspeaker chassis, particularly the midrange Tactic 3.0 drive unit.
STEALTH: CARBON FIBRE COMPOSITE TOP
Wilson Benesch fit a beautifully sculptural carbon fibre composite top to its reference line loudspeakers. The forms are inspired by natural, organic shapes, curves and free flowing lines found in nature.
The carbon fibre tops are extremely complex forms are created using a combination of hand sculpting in clay which are in turn measured using a laser and in turn loaded into advanced 3D digital computer aided design (CAD) software at Wilson Benesch. By importing data in this way, Wilson Benesch are able to use powerful software algorithms to further optimise the 3D form before manufacturing.
When a longitudinal sound wave strikes a flat surface, sound is reflected in a coherent manner. However, the reflective nature of a structure varies according to the shape of the surface. Uneven surfaces will diffract sound wave energy, rather than reflect it directly with little reduction in the energy of the sound wave which it perceived as colouration in the HIFI system. Therefore the complex ‘stealth like’ form is critical to the performance of the loudspeaker. By removing any flat, reflective surfaces and creating a highly complex structure, any reflective sound energy is scattered. This diminishes its energy and also avoids standing wave patterns within the listening space that are easily detected by the human ear as distortion or colouration.
13MM STEEL TIES: COMPRESSION IN THE VERTICAL AXIS
The Endeavour 3Zero enclosure is held under tons of compressive force using 13mm threaded steel bars. The steel bars run the length of the enclosure and the integrated stand. They tie the large precision machined aluminium foot into the elegant base plate and in turn into the Endeavour 3Zero top plate. These vertical steel ties exert tons of compressive force in the vertical axis where the first resonant modes will emerge.

The Audio Beat, Roy Gregory, 2015
The Endeavour is a speaker that challenges assumptions and the status quo. It’s different in its approach, its materials and the way it presents the musical performance. It turns accepted notions of the established audio swings and roundabouts on their head, surprising and delighting in equal measure. But most of all it succeeds in achieving that quality shared by all really great loudspeakers – the ability to put the music first. Self-effacing to a fault, this is in many ways one of the least obviously impressive loudspeakers I’ve heard — that is until you start listening in earnest and ringing the changes. The way and degree to which it responds to input, whether that’s the musical signal or changes in the driving system, underlines just how little of itself it inserts into the process. It gives performers not just a voice but an authenticity in a way that very few other loudspeakers can match.
