The grille assembly consists of a removable outer metal mesh and grille tray unit. The grille’s design allows the enclosure to attach to the wall without making actual hard contact with the enclosure itself.
- Page 7 THE AMPLIFIER The Fathom IWS uses a unique amplifier, specifically engineered to take full advantage of the Fathom IWS subwoofer’s full excursion envelope. There are two amplifier models, a 1kW amplifier for the System One and a 2kW version for the System Two. Both are available as either 120V or 240V AC powered.
