Precision Series 2.5-Way Floor Standing Speaker

Description

The P3.0 is the flagship within the Precision Series and represents exceptional value and performance. It is known as a true high-end audio thoroughbred, delivering scale, authority, a believable soundstage with absolute control while at the same time communicating the tonal nuances that make a performance so emotionally compelling. Three decades of research & development underpin the Wilson Benesch design team. This experience has resulted in the gradual evolution of loudspeaker design culminating in the Precision Series, which distils core Wilson Benesch loudspeaker technologies within its loudspeaker enclosures. With trickle-down technology from the reference Geometry Series evident throughout its design.

1. TACTIC II DRIVE UNIT: ISOTACTIC POLYOPROPYLENE

Arguably the most critical component in any dynamic drive unit design is the choice of material in the cone. Wilson Benesch was the first company in the world to develop a consumer product that used Isotactic Polypropylene. More than a decade on, this remains the material of choice in all our drive unit technologies. It’s unique balance of high specific stiffness with exceptional damping provide what we regard as the optimum balance of material properties. Other hard dome technologies, including that using carbon fibre & ceramic have been extensively tested. Without exception all these technologies result in the need to design complex crossovers to control unwanted resonances within the cone which arise from very high specific stiffness. This complexity within crossover design is regarded as a compromise.

2. TACTIC II DRIVE UNIT: DESIGN PHILOSOPHY

At the very core of the development of Wilson Benesch drive unit technology was the ethos that transient response time should be reduced as much as possible. That is to say the response of the drive unit to change from equilibrium or steady state. There are no delays in nature and yet when a dynamic drive unit attempts to reproduce a range of frequencies from a recording, the laws of physics dictate that the moving mass of the drive unit will always reproduce sound with some delay. This is an unavoidable design limitation of all dynamic drive unit designs today.

However, these physical laws can be observed and used as a guide to optimise the dynamic drive unit design. By introducing light and stiff materials to reduce mass, powerful rare-earth magnets to increase power and control, highly optimised structural design to maximise the unique properties of each material and form within the structure, the Tactic II drive unit is a near optimal dynamic drive unit design.

Wilson Benesch has iteratively developed four drive unit designs. These have been referred to by the independent press as “lightning fast” and “one-third dynamic, two-thirds electrostatic”. Testament to the design ethos at the core of these technological developments.

3. LEONARDO TWEETER

The Leonardo Tweeter has been developed directly through an iterative design approach that gave birth to the Fibonnaci and Semisphere Tweeters before it. Unlike these exotic wide-bandwidth designs, the Leonardo does not employ a hybridised Silk-Carbon dome and thus its frequency response is flat to 24 kHz. However, the geometrically optimised and decoupled polymer-carbon fibre faceplate is taken directly from the same shelf as that used in the Eminence loudspeaker. This entirely proprietary component is manufactured in-house using the latest 3D printing technology. The faceplate acts as a waveguide to guarantee optimal dispersion and phase characteristics for the Leonardo Tweeter. Just like the Semisphere Tweeter, the Leonardo Tweeter features the proprietary Neodymium magnet ring in its rear chamber. This open architecture ensures optimal energy paths for both acoustic and thermal energy; critical design considerations where super low distortion levels are aspired to.

4. ALUMINIUM TOP & BOTTOM BRACING

The Precision Series uses a multi-material hybridised structure. This design philosophy has been developed by Wilson Benesch over three-decades of loudspeaker enclosure design. By combining multiple materials in this way, the designer is essentially forming a composite structure that allows the unique properties of each material to be used to create a design advantage. This exact same hybridised design ethos is used in the reference Geometry Series. The distinct Precision Series top and bottom ‘caps’, whilst elegant forms, are in fact critical components in the enclosure design. Precision CNC-machined from solid billets of aluminium, the caps lock in position the front and rear aluminium baffles with the wood side panels. The caps are then tied along the vertical axis of the Precision Series enclosure using aluminium alloy bars that brace the enclosure and compress the whole structure to ensure it is as sonically inert and stiff as possible. This tie and brace design is used across the Geometry Series and also within the Isobars of the R1 HIFI Rack. This construction technology is another example of trickle-down technologies taken directly from the reference Geometry Series.

5. INTERNAL DAMPING

As the leader in loudspeaker enclosure design, Wilson Benesch incorporated into the design of the Precision Series numerous features that allow the enclosure to be stiffened and damped optimally. Another example of this is seen in the tubular structures that populate the internal enclosure to provide both increased stiffness but also damping of the Precision Series enclosure along its horizontal axis.

6. INTERNAL ENCLOSURE TIES & BRACES

The hybridised Precision Series enclosure is further stiffened and damped using threaded steel bars. The bars terminate into threaded pockets on both the aluminium top and bottom caps, plus the front and rear aluminium baffles. The bars are then torqued to create a compressive force across the vertical axis of the Precision Series P3.0 enclosure. This design feature is used across our reference loudspeaker line and also within the Isobars of the R1 HIFI Rack. This construction technology is another example of trickle-down technologies taken directly from the reference Geometry Series.

Reviews

VUmétre, Issue #72, France, 2019

French audio journal VUmétre have reviewed the Precision Series P3.0 loudspeaker. The review is in French language so those unable to read French won’t sadly be able to enjoy all the content of the review, but we have had a few key sentences translated to share with all of you:

Although many loudspeakers offer real image quality, few are able to overcome the physical limits of the walls or the position of the loudspeaker in the room. With the P3.0s, when one closes the eyes, these physical barriers disappear. There is no longer the sense that the sound is projected from two speakers, instead it is just the music that expresses itself. This sensation of spatial awareness, of freedom, is particularly exhilarating.
They reproduce sonic impact with spontaneity and enthusiasm. The bass register is particularly eloquent. Its legibility and scale are quite exemplary. In addition, we can listen to high levels of sound without noticing the slightest feeling of auditory fatigue. The P3.0 is a master of rhythm, perfectly illustrated with the irresistible swing between the drums and the organ on “Muse 2 The Pharaoh” by Prince during which it is absolutely impossible not to tap the foot.
To say that these Wilson Benesch loudspeakers retain the sound identity of products from the company’s past is obvious. The new Precision Series P3.0 is based upon the same technological blueprint, creating a beautiful sound. It is characterised by a natural clarity, a high-class sense of rhythm and ability to recreate the intimacy of a recording. The low frequency is sovereign, the midrange heady and acute yet subtle. It is able to deliver high quality sound with remarkable consistency. It is recommended you listen to these urgently.
