About Induction Dynamics SW4.IW
The SW4.IW Dual 10 inch in-wall subwoofer with its patented filter circuit and excursion limiter generates true deep, thunderous bass-the foundation of a superb sounding home theater system. The SW4.IW features the Stud-Grabber patented mounting system with suspension springs that attaches loudspeaker directly to wall studs, eliminating vibration on drywall, a problem common to wall-mounted subwoofers. A sealed, heavy-duty one piece aluminum enclosure ensures consistent sound quality. The SW4IW can be used with any Induction Dynamics loudspeaker to add explosive impact to your surround sound system. The SW4.IW comes complete with one A2 Subwoofer Amplifier. Can be mounted horizontally or vertically.
By utilizing acoustic suspension enclosures, high-excursion drivers, and a filter circuit to eliminate resonance peaks, Induction Dynamics subwoofers produce clean, authoritiative bass throughout the entire sub-bass range.
When coupled with an A2 or A3 amplifier, the SW series also takes advantage of a patented frequency-selective excursion limiter. The excursion limiter allows the subwoofer to produce ultralow frequencies, but prevents the driver from moving outside its linear operating range. The limiter is accoustically transparent, operating only at specific frequencies, without audible switching.
