Напольная акустика — Wilson Benesch Resolution 3Zero

The Resolution 3Zero is a floorstanding loudspeaker handcrafted in the UK by Wilson Benesch. The company describes it as a merger of technologies drawn from two other 3Zero models, the A.C.T. 3Zero and the Endeavour 3Zero, placed into a full range tower. North American pricing is listed at USD 79,999 per pair, and bespoke customisation is offered on request.

Key specs that matter

The configuration is described as 2-way electric and 4-way acoustic. Seven drivers are fitted per channel - a 25 mm Fibonacci Hybrid Silk-Carbon tweeter, a 170 mm Tactic 3.0 midrange, a 170 mm Tactic 3.0 low bass unit at the top of the enclosure and two Isobaric Drive Systems, each holding a pair of 170 mm Tactic units in clamshell formation. Frequency response is 30 Hz to 30 kHz within 2 dB, sensitivity is 90 dB at 1 m on axis with 2.83 V, and impedance is 6 ohm nominal with a 3 ohm minimum. Each cabinet stands 1558 mm tall, 191 mm wide at the baffle and 519 mm across the foot, runs 505 mm deep and weighs 98 kg.

Engineering and use context

The tweeter sits behind a second-order 5 kHz high-pass filter, the low bass unit uses a first-order network and both isobaric systems roll off through first-order 500 Hz low-pass filters. The midrange has no crossover in its signal path at all - it is coupled straight to the amplifier and rolled off acoustically. Tactic 3.0 cones carry a Fibonacci Element dust cap made by additive manufacturing from a carbon fibre and nylon layup, and the tweeter motor is decoupled from its carbon composite faceplate. The enclosure is an A.C.T. 3Zero biocomposite monocoque with poly-alloy hybrid construction, capped by a curved carbon fibre Stealth Top that limits reflected energy and standing waves. Low bass and midrange work in sealed infinite baffle volumes, the tweeter in a labyrinth chamber, and the isobaric section vents through a port tuned on the underside.

Pairing

Because the impedance dips well below nominal, a partnering amplifier needs to cope with low loads and deliver current, despite the fairly high efficiency. A bi-wirable terminal panel sits on the foot at ground level, so separate bass and treble runs are possible. Four M28 spikes with 1.5 pitch thread support each channel. Standard finish is textured black, with walnut, burr walnut, ebonised walnut and six automotive paint colours as options, and the isobaric pods come in black, rhodium silver or gold.

Alternatives

The Wilson Benesch Endeavour 3Zero is the floorstanding model in the same 3Zero family that supplied part of this design's technology.
