About the SW2
The ATOHM SW2 is an active subwoofer designed to complement the ATOHM GT speaker range. It features a compact 22-liter closed box enclosure with a dedicated 500 Wrms amplifier module (ATOHM S500 ver. SL3M-X) and two 23 cm midbass drivers (model LD230CRA08M). The subwoofer employs X-guard technology for active excursion control, allowing +/-19mm maximum excursion, delivering exceptional low-frequency reproduction down to 23 Hz at -3 dB. It includes low-level (2x cinch) and high-level (2x 4mm banana plugs) inputs, a low pass crossover adjustable from 38 to 150 Hz, phase control from 0 to 180 degrees, and selectable filtering slopes of 12 dB, 24 dB, or LFE. The cabinet is constructed from 22mm MDF with 42mm multilayer curved sides, finished in piano gloss lacquer available in black, white, or custom RAL colors. Dimensions are 385 x 307 x 375 mm (H x W x D) and it weighs 25 kg. Power consumption peaks at 700 W max. The SW2 is designed for high fidelity and home theater setups, ideally paired with ATOHM GT series speakers.
