User manual SOUNDCRAFT ABSOLUTE ZERO

[. . . ] Trevor's design philosophy behind the Absolute Series is deceptively simple: · Any professional monitor should exhibit an even frequency response at high and low levels, on and off axis; · it should have the most natural, uncoloured sound possible, whatever the price level; · it should not exagerate or enhance sound; · it should not cause listening fatigue (often arising from the inappropriate use of driver materials that produce spurious resonances masking the monitor's true sound); · it should be reliable in prolonged, professional use. To satisfy these criteria, Trevor has scrutinised every element of Absolute Zero's design to optimise its performance. The sturdy, vented cabinet design complements the 170mm low-frequency driver to give smooth, extended bass response and the soft-dome tweeter is mounted in a proprietary waveguide to ensure controlled dispersion. [. . . ] To satisfy these criteria, Trevor has scrutinised every element of Absolute Zero's design to optimise its performance. The sturdy, vented cabinet design complements the 170mm low-frequency driver to give smooth, extended bass response and the soft-dome tweeter is mounted in a proprietary waveguide to ensure controlled dispersion. In the tradition of all good monitors, the wide frequency response remains even at all listening levels, both on and off axis - so you can be assured of consistent, dependable results every time. Furthermore, special attention has been paid to the impulse response of the system in order to give the most natural, uncoloured sound possible. Absolute Zero offers superb all-round performance, is remarkably versatile and comes at a price that is truly affordable. http://www. spirit-by-soundcraft. co. uk THE MAIN FEATURES · High definition Linear Phase design · Flat on and off axis frequency response · Wide, controlled dispersion · CAD optimised, low loss crossover · Custom designed drivers · Long throw 170mm LF driver · 25mm soft dome HF unit on proprietary waveguide · Ported cabinet for extended LF response at all listening levels THE INSIDE STORY The Tweeter Absolute Zero's tweeter is a customdesigned catenary-profile soft dome unit which exhibits all the extended high frequency characteristics of standard metal dome tweeters, without sharing any of their harshness. The tweeter is recessed to help protect it from surface impacts. USING ABSOLUTE ZERO The in-line driver array, with its wideangle tweeter, means that Absolute Zero may be used horizontally or vertically. Absolute Zero's controlled dispersion of high frequencies means you hear more of your music and less of your room. Many monitors utilise deep port designs positioned at the front of the cabinet, which can cause midrange response to vary by as much as 6dB. Absolute Zero's deep port is rear facing, guaranteeing midrange consistency. The Cabinet Many small cabinet speakers suffer from diffraction problems in the upper-mid frequencies caused by sharp vertical edges. In contrast, Absolute Zero's vertical edges are contoured to minimise diffraction from reflected sounds. The Connectors Poor quality connectors are often the weakest link in the signal path, reducing signal quality from amplifier to speaker. Absolute Zero uses only top-grade gold plated binding posts which give better contact for many years. 110 SPECIFICATIONS Power handling (typical music signal content): 95 Watts RMS 8 nominal 2. 5kHz 89dB/2. 83V/1m 170mm LF/25mm HF 320 × 230 × 290mm 12. 6 × 9 × 11. 4 in Weight: 11kg (24lbs) per pair dB 100 90 Custom Components Many of Absolute Zero's components, including its tweeter and bass driver, are exclusive to Spirit to ensure that performance is not compromised by the use of off-the-shelf designs.
