XTO S218F는 XTO S218의 플라잉 버전입니다. 동일한 듀얼 18인치 음향 설계, 동일한 카디오이드 준비 구성, 다른 리깅: 공용 XTO 트랙을 사용하므로 별도의 리깅 언어나 별도의 예비 부품 목록 없이 메인 행잉 위나 옆에 자체 컬럼으로 플라잉됩니다. 저역을 쌓는 대신 플라잉하는 것은 스타디움 볼에서 앞뒤로 균일한 커버리지를 확보하는 방법이며, 카디오이드 플라잉 컬럼은 스테이지와 어레이 뒤쪽 좌석에서 저역을 차단합니다. 지상 적층 아크와 엔드파이어 블록은 여전히 그 자리가 있으며, S218은 이를 위한 박스로 남아 있습니다. 대부분의 대형 시스템은 결국 두 가지를 모두 운영하게 됩니다.

Part of the XTO System

The flown dual-18. Rides the shared track above or beside the main hangs, cardioid ready.

XTO stands for Xtended Touring Output. The large-format touring platform: the elements built for the longest throws and the highest output in the range, rigged and amplified as one system.

Key features

  • Flown dual-18″ subwoofer module of the XTO System
  • Rides the shared XTO track above or beside the main hangs
  • Cardioid ready
  • Same acoustic design as the ground-stacked XTO S218
  • One D24X channel per subwoofer

Measurement conditions

  1. Maximum SPL is the peak level at 1 m, driven with pink noise at crest factor 4 to the clipping point of the recommended amplifier, with the SSOUNDS system preset applied. Full-range enclosures are specified under free-field conditions; figures marked half-space are specified over a reflecting plane, the condition subwoofers are deployed in, which adds approximately 6 dB.
  2. Frequency response is specified on axis at 1 m in a free field. The tolerance the figure is referenced to is stated alongside it; where no tolerance is given, the figure is the −6 dB bandwidth.
  3. Sensitivity is specified at 1 W into the nominal impedance at 1 m on axis, averaged across the pass band of the enclosure.
  4. Recommended amplifier power is the amplifier output SSOUNDS specifies for this enclosure, driven with the SSOUNDS system preset. It guides amplifier selection and is not an AES power-handling rating for the transducers.
  5. Nominal impedance is the manufacturer's rating for amplifier load calculation; minimum impedance across the operating band may be lower.
  6. All figures are typical values for production units specified under the conditions above. Individual units may vary within published tolerances.

System operation

Recommended: SSOUNDS D24X, one channel per XTO S218F (4 Ω) with the S218 preset loaded. Cardioid presets are supplied for three- and four-box columns. A flown subwoofer column is normally run as its own zone, so its arrival time and its cardioid rear rejection can be set independently of the ground-stacked arcs.
