Bowers & Wilkins CT8 SW Custom Theatre Subwoofer

Integral to the system’s no-compromise approach to bass management is the subwoofer, illustrated here with a pair deployed at extreme left and right for low frequencies that will push your sound envelope to the limit. The Bowers & Wilkins CT8 SW features a 15” driver. Like all the bass drivers in the range it features a rigid composite sandwich cone.

Bass Drivers

As you might imagine, one of the secrets of developing a high performance bass driver is finding a cone material with high enough strength to keep its shape under the heaviest of strain, yet not too heavy that it loses its responsiveness.

The choice is a modern carbon fibre and rigid foam sandwich construction used in car and aircraft bodies. Its outstanding mechanical properties and relatively low mass make it tailor-made for the job of turning low frequency effects into real-life sound.

About Bowers & Wilkins

1960s: Humble beginnings

The sleepy coastal town of Worthing in South England might not look like a hotbed of 1960s freewheeling experimentation, but for audio fans it’s a place that’s synonymous with innovation. Thanks to the first Bowers & Wilkins speakers built here in the early years of the company, music lovers could experience albums such as Sgt. Pepper and Pet Sounds in new, mind-expanding depth and clarity.

1970s: A decade of milestones

The decade that saw a series of musical upheavals from disco to punk rock also brought several major milestones for Bowers & Wilkins. The company introduced curved cabinet forms and new cone materials such as Aramid fibre. And it all culminated in the launch of the 801, soon to become the reference speaker of choice for many of the world’s leading recording studios.

1980s: The application of science

Extensive investment in research led to the establishment of the company’s dedicated R&D facility in Steyning. The era of MTV pop superstardom and bombastic stadium rock also saw Bowers & Wilkins buck the trend and introduce something small and unobtrusive: the “compact monitor”, or CM1.

1990s: Rewriting the rulebook

The 1990s saw the pioneering work of the Steyning research team realised in spectacular fashion with the launch of Nautilus™, a speaker that upended preconceived notions of speaker design. It also saw major product launches at both ends of the spectrum, with the unveiling of the highly regarded entry-level 600 Series and the flagship Nautilus 800 Series.

2000s: Hi-fi goes digital

The decade that brought us iPods and smartphones saw us embrace the new world of digital with the launch of the Zeppelin. We also expanded into the car audio market with our partnership with Jaguar, and launched a revolutionary new speaker technology in the form of diamond tweeter domes.

The 2010s: Innovation overdrive

Monumental technological change seemed to be everywhere in the 2010s, and Bowers & Wilkins was no exception.
