Seaton Sound SubMersive SM-215-1B active subwoofer. 2×15″ woofers. 115V/230V selectable. $3,200

This may look like one big innocuous black “box” but this 23.5″ x 25.5″ x 17.5″ (WHD) cabinet houses two 15″ woofers (side firing), a 1,000W amp that blows other big subwoofer brands out of the water for its price/performance ratio. Whether it is being used in home theater setup or for music, the Seaton Sound sub delivers thunderous bottom end that is so clean and precise and yet almost destructive to the walls in your room. This sub can certainly rattle the walls in our sound room! Setup is a breeze and uncomplicated. Just run your sub out from your preamp/AV pre (XLR only or use a RCA/XLR adapter) and adjust the volume of the sub. That’s it. If you want to trigger a seismic event, we have two more (contact us for a package price) which you can run in conjunction to be the number one enemy in your neighborhood. Voltage selector switch on the back allows switching between 115V and 230V so it can be used anywhere in the World.
