Solitaire High End Loudspeakers
The CWT 1000-40 Anniversary Edition
To mark our fortieth anniversary we carried out additional intensive development work to produce the Solitaire CWT 1000-40 as a symbol of our power of innovation. More than three years of exhaustive research lies behind the development of a unique technology which raised the spatial and imaging characteristics of floor-standing speakers to a new and unprecedented level: The “organic baffles” are machined from solid material, and incorporate accurately calculated sound guides for each individual drive unit. We invested enormous effort in the detail design, and succeeded in completely avoiding all screws, baskets or edges which could interfere with the sound.
Our forty years of experience were reflected in the development of new baffles, but also in carefully optimised cabinet construction designed to eliminate structural sound and resonances: For example, the cabinet walls and dividing floors are produced as multi-layer laminated wood panels employing materials of differing density; these measures significantly increase the rigidity of the cabinet. Multiple applications of priming lacquer are sanded between coats before the final lacquer is applied and given a last manual polish. The carbon version not only looks great, but also achieves enormous rigidity and freedom from resonance. In this process, real carbon fabric is laminated to the surfaces under high pressure and sealed several times in layers with PU special lacquer before the final lacquer is applied. Alternatively, you can order your Solitaire painted in any RAL hue and many special paint types. They are lacquered individually for you.
CWT 1000-8 SE
The CWT 1000-8 SE
In the truest sense of the term, the CWT 1000 SE is the slightly smaller brother of the CWT 2000 SE. Its overall design is identical, but the cabinet and the mid-range and bass drivers are slightly smaller. The CWT 1000 has been revised and has received two additional mid-range drivers, which improve the radiation pattern in the crossover section between mid-frequency and high-frequency range. The electrostatic unit is of identical construction to that of the CWT 2000, and its circuitry is similar. For this reason it is equally effective at transmitting the entire high-frequency range from just under 2000 Hz to more than 40 kHz – even well off-axis! The 12 cm mid-range unit is of similar design to the 15 cm mid-range driver, and offers the same superb ability to handle the full vocal range from 200 to 2000 Hz. Once again this unit’s outstanding attributes are its dynamic ability, its inherently lively nature, and its unbelievably natural sound. With this size of cone a phase plug is not sensible, and unnecessary in any case.
A sealed cabinet offers many advantages, but the design is extremely demanding when required to generate a very low cutoff frequency. This calls for bass units with a very low resonant frequency, capable of extensive excursion, with an exceptionally powerful magnet, and designed to cope with extreme loads. Our drive units fulfil these requirements perfectly! Since the speaker units are subject to enormous acceleration forces, the cones are impregnated with an extremely hard fibre / carbon mixture. The demands on the dynamic ability of the mid-range drivers are very high, since the electrostatic unit and the bass units exhibit very sophisticated excursion characteristics, and are capable of generating very high sound pressures. For this reason the new mid-range drivers are amongst the most advanced in existence: this superb unit features a gigantic magnet, a large coil, an effectively damped cone with integral stiffeners and a modern diecast aluminium basket.
CWT 2000 SE
The CWT 2000 SE
The flagship of the SOLITAIRE® is the CWT 2000 SE, a really large floor-standing loudspeaker. This unique and exemplary speaker demonstrates the technological philosophy and ultimate sound quality of the whole series, and provides impressive proof of the potential performance of our newly developed loudspeaker systems. The electrostatic tweeter transmits the entire high-frequency range from just under 2000 Hz to over 40 kHz, and even well off-axis! The mass of the membrane is virtually zero, enabling the unit to offer fantastic dynamic characteristics; it is capable of effortlessly reaching extremely high levels, without compression effects. At the same time the total harmonic distortion always remains below 0.5%; this is a unique performance.
Electrostatic units are amongst the oldest of all loudspeaker designs, and as ever they remain peerless in terms of their dynamic qualities and their ability to resolve fine detail in the mid / high-frequency range. However, they are not exactly easy to make, and are very expensive to produce. Here at T+A we have been making electrostatic tweeters for more than 25 years, and have built up an enormous store of expertise. Despite this wealth of experience, we have deliberately chosen not to build full-range electrostatic speakers, because these always have a major weakness in the bass range; instead we exploit their strengths in the mid-range / high-frequency area. The membrane consists of an extremely thin film which has virtually zero mass, and is driven by a powerful electric field. The peak-handling and transient response characteristics are therefore not subject to inertial effects, and this explains the unexcelled clarity and purity of reproduction, entirely devoid of any hint of sharpness or hardness, even at very high levels. Both dynamically and tonally, this unique speaker unit harmonizes perfectly with the mid-range array and bass drivers.
