Tweeter diaphragms must be light and stiff, to reproduce high notes accurately. Bowers & Wilkins' Double Dome tweeters use a thin and light aluminium dome, surrounded by a thicker ring, to prevent audible distortion. 600 Series tweeters are further 'Decoupled' from the cabinets to reduce vibration.
Not all sound is good. Sound from the rear of a driver or tweeter can bounce around a cabinet and undermine the good sound coming from the front. Nautilus Tapering Tubes, filled with absorbent wadding, reduce unwanted sound to a minimum.
Preventing cabinet vibrations reaching the tweeter leads to cleaner, sweeter high-frequency performance. Synthetic gel cushions a Decoupled tweeter, with the assembly isolated from the mounting. The result is a more natural, spacious sound.
The same properties that let Kevlar stop a bullet also make it ideal for soaking up standing waves in a speaker cone, so they don't colour midrange sound. That's why our midrange cones have been made with Kevlar since 1974. It delivers a cleaner sound, to a wider group of listeners. The new 600 Series continues this trend.
'Fixed Suspension Transducer' Kevlar cones are mounted in a narrow ring of foam. This 'surroundless' suspension minimises distortion by converting unwanted energy into heat, not sound. The result is the cleanest midrange around.
Unlike most dust caps, these mushroom-shaped devices - first seen in the PM1, and now in the 600 Series - fit tightly inside the voice coil bobbins. This ensures better pistonic movement, reducing higher-frequency break-up for a superior performance.
In the 600 Series, both the 683 and HTM61 speakers feature improved bass drivers that feature a new Dual Layer aluminium construction, similar to that of the new Double Dome tweeter. This new construction technique shifts the break-up frequency of the driver from 4kHz to 5.5kHz, ensuring a richer, distortion-free bass response and improved integration with the midrange.
The surface dimples around the 600 Series Flowport minimise turbulence by generating tiny eddy currents over which air can flow smoothly, like a golf ball. This reduces turbulence and leads to improved bass response at higher volumes.
The crossover sends the audio signal to the right driver, depending on frequency. The simpler this vital component is, the better. And the better the drivers, the simpler it can be. In the 600 Series the high-frequency crossover uses just one capacitor.
MT-50 combines the M-1 loudspeaker, with the incredibly compact, yet powerful, ASW608 subwoofer for an unbelievable surround sound experience.
The highly refined PM1 is a compact loudspeaker that offers audiophile-quality performance and features the new Bowers & Wilkins Carbon Braced Tweeter.
