Sonance i12 – 12-Inch Impact Series Powered Subwoofer

Product Overview

The Sonance i12 is a 12-inch powered subwoofer from the Impact Series, the largest and highest-output cabinet in the lineup. It is intended for larger home theaters and living rooms where cable runs to a source location are impractical or undesirable. A built-in 400-watt amplifier and high-excursion glass fiber driver extend response down to 22Hz.

Product Description

At the top of the Sonance Impact Series, the i12 uses a 12-inch ultra-long-throw glass fiber cone with a rubber surround, a front-firing, laminar flow ported design, and a sealed 400-watt RMS amplifier plate, rated 22Hz to 250Hz (±3dB). Like the i8 and i10, it includes a built-in wireless receiver compatible with an optional Sonance Wireless Transmitter for roughly 30 feet of placement flexibility. The SonARC app manages setup and provides room correction with 16 bands of adjustable EQ so integrators can tune the i12 for larger or more acoustically challenging rooms. At 16.0 inches wide by 18.0 inches high by 16.25 inches deep and 55.5 pounds, it is the heaviest cabinet in the Impact Series, finished in high-gloss piano black with a black cloth grille to match the rest of the line. Because it is self-powered, the i12 integrates into an existing AV receiver or amplifier setup without a dedicated subwoofer channel.
