Bowers & Wilkins 700 Series Signature Speakers

Bowers and Wilkins recently revealed it will produce Signature versions of two 700 Series speaker models: The 705 floorstander and the 702 bookshelf. The company touts a more refined and optimized crossover as well as finer fit and finish as differentiating factors versus the "standard" 700 Series models.

Here is the full press release:

N. Reading, MA - June 24, 2020: Signature product launches are rare and special events in Bowers & Wilkins’ 54-year history, but when the world-leading specialist audio brand attaches the name Signature to its loudspeakers, you can be sure the results are very special.

This month sees the introduction of two new Signature versions of premium loudspeakers from the Bowers & Wilkins 700 Series range: the stand-mount 705 Signature and floor-standing 702 Signature.

The new 705 Signature and 702 Signature models share a common philosophy with their predecessors: like previous Signatures, the new models are carefully upgraded and lavishly finished loudspeakers that represent the apex of current Bowers & Wilkins design, engineering and manufacturing processes. A huge amount of care and attention has been paid to improving their acoustic performance via an upgraded crossover design, and also to carefully crafting the luxurious new cabinet finish.

Launched in 2017, the elegant Bowers & Wilkins 700 Series range of speakers already delivers exceptional performance thanks to its careful use of technologies first seen in the high-end 800 Series Diamond, such as the Solid Body Tweeter-on-Top assembly, unique Continuum cone drivers and Aerofoil profile bass drivers. Used in combination with bespoke 700 Series technologies such as the Carbon Dome tweeter plus carefully optimized and rigid cabinets, the result is a range of loudspeakers as superb to listen to as it is to look at.

As Signature products, the new 705 & 702 Signature have received further, detailed improvements enabled by upgraded crossover designs and components.

Both models now feature specially treated and upgraded bypass capacitors sourced from Mundorf, larger heatsinking and, in the case of the 702, an upgraded LF capacitor on the bass section of the crossover. In tandem with the immense benefits both models enjoy as a result of their Tweeter-on-Top configuration, these upgrades improve the already-remarkable resolution, openness and spatial retrieval on offer, lending them an even-more polished, refined and involving sound.

Upgraded finish

Keeping up with established Signature practices, the 705 and 702 Signature boast a stunning new Datuk Gloss ebony-colored veneer with a distinctive, beautiful grain. This custom-designed finish combines the beauty of exotic real-wood veneers with the environmental benefits of a sustainably-sourced supply, in this case from specialist Italian wood company Alpi.

Each pair of speakers is unique, with no two models sharing the same grain pattern or figuring. Bowers & Wilkins adds to Alpi’s painstaking workmanship by applying nine coats of finish – including primer, base coat and lacquer

– to create a deep, lustrous appearance. To further accentuate and highlight the quality of finish on each model, both Signature speakers have bright metal trim rings around the mid/bass and midrange cones plus bright, silver- finished tweeter grilles. Finally, both models have a Signature identity plate on their rear panel, turning each speaker into a genuine and unique piece of art.

Exceptional engineering on-board

Carbon Dome Tweeter

Both 700 Series Signature models feature Bowers & Wilkins Carbon Dome tweeter technology. Designed to bridge the performance gap between the Aluminum Double Dome used in the 600 Series and the Diamond Dome used in the 800 Series Diamond, the Carbon Dome is composed of two sections. The front portion is a 30-micron aluminum dome that has been stiffened by a PVD (Physical Vapor Deposition) coating of carbon. The second section is a 300-micron carbon ring that has been profiled to match the form of the main dome. This is then bonded to the inner face of the structure. The outcome is exceptional stiffness and resistance to distortion without undue mass and a first break-up point of 47kHz.

Solid Body Tweeters

As with all preceding Signature products, the 705 Signature and 702 Signature are Tweeter-On-Top designs featuring, in this case, Solid Body Tweeter technology. This design is derived entirely from the approach used in the 800 Series Diamond and has the same performance benefits. As with the 700 Series speakers, instead of using a hollow zinc housing, the new Signature models use the same shape milled from a solid mass of aluminum to provide a stiffer and less resonant structure. Weighing over 1kg, it is exceptionally inert, and benefits from the same decoupling mechanism and acoustically transparent grille design as the 800 Series Diamond. This design also allows the use of the mass of the tweeter body as a heatsink for the dome.

Continuum cone

Continuum cone midrange drivers were first seen in the 800 Series Diamond. The Continuum cone’s design is based on the concept of optimized and controlled flexibility. This helps the cone to avoid the abrupt transition from pistonic to break-up mode behavior that drastically impairs the openness and neutrality of a conventional drive unit. Continuum is a woven composite that gives highly controlled break-up, for a more transparent and detailed midrange.

Midrange chassis

The 702 Signature is equipped with a dedicated midrange FST drive unit using a FEA-optimized aluminum chassis with a very stiff optimized form, further enhanced with the addition of a tuned mass damper on the front face of the chassis. This dampens any remaining resonance in the structure, resulting in a cleaner midrange presentation.

Midrange decoupling

The midrange decoupling system simplifies the design used in the 800 Series Diamond for a significant improvement
in midrange spaciousness across the board.

Aerofoil-profile bass cone

A new implementation of the Aerofoil cone used in the 800 Series Diamond is featured on the 702 Signature, using a composite structure of inner and outer skins filled with EPS. The result is a dramatic uplift in bass performance.

First sentence correction needed. "Bowers and Wilkins recently revealed it will produce Signature versions of two 700 Series speaker models: The 705 floorstander and the 702 bookshelf."

Any integrated amp brand/model recommendation(s) for the 702 floorstander?

I use Simaudio mono amps with the 702 S2 with excellent results. One of their integrated Amps with streaming would be excellent.

I use three 400m for the front three. well I use 400m with everything. Speakers come and speakers go. My amps remain and have done well with Dynaudio, KEF and Bowers.

I will need to track down the signature series for a listen.

I just read a very detailed and thorough review Demoing the 705 Signatures against the Martin Logan Motion 60XTi's which I'd love to demo or even buy. In summation the XTi's stood out in the bass section against the 705S's as the XTi's are capable of reaching 23Hz @F3. However even though the Motion's are very good imaging speakers the 705S's were noticeably better in there midrange section which to me is where the meat and gravy is in your speakers, a poor midrange and it doesn't matter how good your woofer is. Bang for the buck though the reviewer thought the XTi's were the way to go so my guess is that the mid's on the XTi's were still strong enough even though the 705S's were stronger.
