Overview
The XTO 12P is the workhorse element of the XTO System, the SSOUNDS large-format touring platform. Twin 12″ drivers, a 10″ high-excursion midrange and dual 3″ compression drivers deliver 149 dB peak SPL with response reaching 35 Hz. Quad-amplified via system DSP with an 8-pole Socapex touring loom, Fast-Set 0°–7° splay rigging on high-grade titanium hardware, and 18 mm Baltic birch construction with Polyurea finish. It flies on the same rigging language, the same amplifier platform and the same preset library as every other module in the system, so a design scales up or down without changing method. Above it sits the XTO 14P for stadium-scale hangs. Below roughly 18,000 capacity the 12P is usually the right answer, and it is the box we fly when the show cannot be anything less than perfect.

Notes
- 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.Coverage angles are nominal −6 dB values averaged across the pass band. Per-octave directivity data is available from SSOUNDS system design support for prediction and modelling.
- 5.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.
- 6.Nominal impedance is the manufacturer's rating for amplifier load calculation; minimum impedance across the operating band may be lower.
- 7.Net weight excludes packaging, flight case, accessories and optional rigging hardware.
- 8.Dimensions are stated in millimetres and exclude protruding rigging hardware, handles and connector panels unless noted.
- 9.All figures are typical values for production units specified under the conditions above. Individual units may vary within published tolerances.
Response
Frequency response: 35 Hz to 20 kHz (−10 dB) · 1/24-octave smoothed
−6 dB horizontal beamwidth: 100° nominal
Plot conditions. Curves are generated by the SSOUNDS engineering toolchain from this product's specification. Frequency response is shown 1/24-octave smoothed, normalised to the midband reference, with the passband corners at the stated tolerance; response varies within ±1 dB across the passband with a subtle shelf in the top octave. Magnitude slopes are 24 dB/octave beyond the passband corners. The beamwidth curve shows the −6 dB included angle: nominal coverage holds down to the pattern-control limit set by the cabinet width (f ≈ c/w) and widens below it.

Charts span 35 Hz to 16 kHz, this cabinet's own operating band. The single-cabinet charts rate one element. Vertical pattern below the midrange is set by the length of the array, not by one box: the 12-element chart is a straight column of 4.32m at 0° splay, and it is the figure to design from. Horizontal coverage is a property of the cabinet and does not change with array length.

Frequencies in Hz. A dash means the column is not yet long enough to hold a pattern at that frequency and radiates through the full vertical plane. Straight hang, 0° splay: splaying the array trades pattern width for reach and widens these figures.
Chart conditions. Directivity charts are computed by the SSOUNDS system prediction engine as a phase-coherent wave solution of this product's driver complement: each way represented by its physical radiator (rigid-piston cones with real diameters and spacings; waveguides as continuous mouth apertures, holding the rated coverage on a flare-controlled axis above the mouth's pattern-control limit and radiating the mouth's own diffraction limit on a wavefront-shaped axis; a horn-loaded mid shares the high-frequency mouth), summed as complex pressure through crossovers at the published points in the topology the cabinet is driven with (linear-phase FIR where the ways run on separate channels of a system DSP amplifier, Linkwitz-Riley where a passive network splits them), with way alignment referenced on axis and 1/24-octave band-power resolution. Single- cabinet vertical figures are free-field beamwidths of one element; the published per-element vertical coverage of a line array is its rigging splay, the sector one element covers in a curved hang. Cabinet edge diffraction, horn loading detail, driver breakup and production tolerances are outside the computation. Directivity files for prediction software (GLL/CLF) are issued from measured data only.

System operation
Recommended: SSOUNDS D24X quad amplifier, two XTO 12P per amplifier, each channel driving the same section (LF1, LF2, MF, HF) across both cabinets. Two 8 Ω sections in parallel present 4 Ω per channel. Two cabinets per amplifier is a design choice, not a limit: it gives the resolution to gain-shade and HF-shade the array zone by zone, and to set far-throw and downfill sections independently of the main hang. Load the XTO 12P preset and run the Socapex loom carrying LF1, LF2, MF and HF. The XTO 12P locks with XTO 10P and XTO 8P via transition hardware, so a single hang can carry a 12P main section over a 10P/8P downfill. Typical deployments, 12 × XTO 12P flown per side with 6 × XTO S218 ground-stacked: stadium and festival main hangs. 8 × XTO 12P with 4 × S218: arena and large open-air. 6 × XTO 12P over 4 × S218: large auditoria and stadium worship.
