CM1 Awarded EISA 2006-2007

Official Quote from EISA:-

"B&W's CM1 is a masterpiece in the audiophile class of mini-monitor loudspeaker. Physically small but big-hearted, the CM1 plays music with passion, having a full-bodied bass with fresh, clean and sweet highs. The acoustic concept is based on a minimalist first-order crossover using a carefully selected high-grade capacitor, united to the now-familiar B&W Kevlar and aluminium diaphragms drivers, here tuned to work at its optimum with the purer type of filtering. And the look of CM1 perfectly suits its sound - a simple, traditional shape of box, beautifully finished in natural veneers in fashionable colours, with polished aluminium rings to complement its drive units. The CM1 gives more than a touch of high-end quality at a comparatively modest price."

The CM1 mini-monitor was designed and developed in tandem with the 805s from the 800 Series and shares that model's driver and crossover technology, along with its remarkable musical ability. It continues a long and distinguished line of compact and inherently accurate monitors that have an uncanny ability to re-create an utterly convincing portrayal of music's dynamics, colour, energy and beauty.

The driver line-up of a 130mm Kevlar cone bass/midrange and 25mm Nautilus tube-loaded aluminium dome tweeter endow the CM1 with a striking ability to resolve fine musical detail and its first order crossover topology, made possible by the remarkably wide bandwidth of the drivers, ensures it makes music as a seamless, cohesive whole. The Nautilus tweeter also extends the CM1's frequency response to above 50kHz. Despite its small size the CM1's low frequency performance balances perfectly its transparent and extended midrange and high frequencies. Flowport technology to minimise turbulence, and a bass driver featuring magnet system technology that reduces distortion, mean that CM1 bass is deep, fast, tuneful and always under control. An optional port sleeve that modifies the low frequency response shape allows positioning of the speaker right up close to room boundaries without musical compromise.

The CM1's cabinet is a classically manufactured and exquisitely veneered expression of the cabinet makers art and provides a visually understated and mechanically rigid enclosure for the drivers. Real wood finishes in Wenge, Rosenut and Maple are available. And removing the magnetically attached black or dark grey fabric grille to view the drivers reveals no unsightly grille mounting features. Shelf or wall bracket mounting is perfectly feasible for the CM1 but a matching floor-stand, the FS 700/CM, is available and provides optimal performance.

Kevlar has properties that benefit the cones of wide bandwidth drivers as well as bulletproof vests.

Flowport uses golf ball aerodynamics theory to achieve lower turbulence distortion in reflex ports.

Tapered tubes filled with fibrous material effectively absorb the unwanted sound from the back of a drive unit.
