Solton aart S THREE is a professional-grade PA package consisting of two active aart T 15 A+ full-range cabinets and two active aart SUB 18 A subwoofers. Every component runs its own integrated amplifier and DSP — the set requires no external processing or amplification and is operational straight out of the cases.
aart T 15 A+ — 15" Neodymium top with FIR DSP
The aart T 15 A+ uses a 15" Neodymium LF driver on a 3" (75 mm) voice coil paired with an HF compression driver on a 3" voice coil — Neodymium magnets deliver higher efficiency at the same power rating compared to ferrite drivers of equivalent size. The two-channel Class D amplifier runs a two-channel DSP with FIR filtering, which corrects phase distortion that conventional IIR crossovers introduce — the result is tighter transient response and better stereo coherence when the two tops are deployed wide. Four DSP presets cover fullrange, MF/HF, stage monitor and install scenarios. The 90° x 60° horn is user-rotatable without tools, allowing the cabinet to flip between vertical and horizontal orientation on the fly. Seven M8 inserts support flying, truss mounting and wall-bracket installations. Mic/Line input with high-resolution preamp and switchable Mix OUT allow zone extension without an additional mixer.
aart SUB 18 A — 18" subwoofer for serious mobile and installed work
The aart SUB 18 A uses an 18" long-excursion driver on a 4" (100 mm) voice coil in a compact bass-reflex enclosure, driven by 800 W continuous / 2400 W peak Class D power. The variable crossover between 80 and 200 Hz lets you match the handoff to the T 15 A+ or any other top without external electronics. The M20 pole socket accepts a satellite directly on top, building a complete main-PA stack in seconds. Optional 75 mm casters and the TU Frame flying bracket mean the same cabinet works as a ground-stack base or a flown sub in permanent installations. With two units running, the system delivers 1600 W continuous of low-end headroom — enough for rooms of 500 to 1000 people at moderate SPLs.
