Solton aart S ONE is an active PA package consisting of two aart T 12 A tops and two aart SUB 15 A subwoofers, delivering 2600 W total continuous acoustic power. Every unit carries its own amplifier and DSP — the system is operational without any outboard gear the moment a signal source is connected. Compared to the S TWO, the key difference is the 15" subwoofer in place of the 18", cutting sub weight nearly in half and making single-operator load-in genuinely practical while keeping the same top-cabinet power.
aart T 12 A — 12" Neodymium top with bi-amp DSP
The aart T 12 A runs a 12" Neodymium LF driver with a 3" voice coil and a 1" exit HF compression driver on a 1.75" voice coil, driven by a dual-channel Class D bi-amp with integrated DSP. Four factory presets cover fullrange, MF/HF, stage monitor and fixed-installation scenarios without changing any cabling. The 90° x 60° constant-directivity horn rotates by hand, so the cabinet switches between vertical and horizontal orientation in seconds — useful for wall brackets, monitor positions, or satellite-on-sub stacks. Mic/Line input with preamp and switchable Mix OUT allow zone daisy-chaining without a separate mixer. The dual-band limiter protects LF and HF drivers independently. The multi-angle 15 mm birch plywood enclosure has seven M8 inserts for flying, U-bracket, speaker stand or wall-mount use.
aart SUB 15 A — compact 15" subwoofer for mobile applications
The aart SUB 15 A uses a 15" long-excursion driver on a 4" (100 mm) voice coil in a bass-reflex enclosure, driven by 800 W continuous and 3200 W peak Class D power. The variable crossover from 80 to 200 Hz with a phase switch handles integration with the T 12 A precisely without any outboard processor. Two XLR/Jack Combo inputs and two XLR link outputs support stereo sub pairing or daisy-chaining to additional zones. The M20 pole socket accepts the T 12 A satellite directly on top. At 31 kg and 460 x 590 x 580 mm the sub is substantially lighter and more compact than an 18" cabinet — a meaningful advantage when one or two people are running the full load-in and setup without crew support.
