إن XTO S18 هي وحدة مضخم الصوت الفرعي أحادية مقاس 18 بوصة من نظام XTO، بتصميم نطاق عابر مصمم كشريك الترددات المنخفضة لعناصر المصفوفة: امتداد عميق وقوي على محرك ملف صوتي مقاس 5 بوصات، مع إخراج بمستوى الجولات، ومسار التعليق والمقابض ونظام العجلات المشترك عبر النظام بأكمله. تُعلَّق مع الوحدات العلوية على نفس العتاد، لذا يكون التعليق قرارًا واحدًا للتجهيز بدلاً من قرارين.

Part of the XTO System

Single-18 subwoofer, flyable on the shared track, for arrays that hang with the tops.

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

  • Bandpass single-18″ with a 5″ voice-coil driver
  • 35 Hz low-frequency reach and 137 dB peak SPL
  • Cardioid-capable when arrayed
  • Fly track and caster dolly shared across the XTO touring inventory
  • 18 mm Baltic birch with Polyurea finish
  • CardioSteer presets steer low-frequency energy off the stage

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. Net weight excludes packaging, flight case, accessories and optional rigging hardware.
  7. Dimensions are stated in millimetres and exclude protruding rigging hardware, handles and connector panels unless noted.
  8. All figures are typical values for production units specified under the conditions above. Individual units may vary within published tolerances.

Directivity

Directivity computed by the SSOUNDS system prediction engine from this product's driver complement, the same dataset the printed data sheet uses. 1/24-octave band-power resolution; values are dB relative to on-axis.

System operation

Recommended: SSOUNDS D24X, up to 2 × XTO S18 per channel (8 Ω) with the S18 preset loaded.
