Atohm has some very secret sauce in its Sirocco 2.24 high performance tower. Atohm has created SWD (Standing Wave Damper) technology. Its purpose is to eliminate extraneous cabinet ringing. By controlling cabinet resonance with a vice grip the 2.24 is perspicaciously taut in its mid & bass response which allows pianos, bass fiddles and drum kits to attain accurate, rather than bloated timbre.

SWD is more advanced than what the other guys do in terms of tuning cabinet resonance.
Everyone else makes a box and runs some manner of port or passive radiator. These methods are traditional, cost effective and worthwhile. Atohm goes to another level of sophistication.
SWD is an internal cabinet chamber used to minimize resonance and standing waves, specifically in the lower midrange and upper bass regions. The damped chamber acts as a choke which behaves as an impedance matching transformer- mechanically.
The SWD chamber enables Atohm speakers to be bereft of midrange and bass murkiness.
After hearing a market full of chesty-thumpy speakers, Atohms deliver resolution that often exceeds frightfully expensive flat panel designs.
The other clear advantage of SWD is improved transient response- as there is less cabinet resonance in the way of the music. All of the Atohm GT Series and Sirocco Series speakers employ this SWD technology.
Perhaps you’ve read in my other writings that Atohms sound even more clear than flat panels. SWD is one more log on the fire to attain this superb level of definition.
