SoundTube SW4 10-Inch Subwoofer, Black Gloss Finish

The Induction Dynamics SW4 is a compact, sealed 10″ subwoofer engineered to deliver true deep bass down to 25 Hz with minimal distortion. Its sleek Black Gloss enclosure occupies less than one cubic foot, making it ideal for home theaters, studios, or distributed bass applications around a room.

Featuring a high-saturation filter circuit to eliminate resonance peaks, the SW4 employs a cast‐frame driver with rubber surround and a 54 oz magnet on a mica graphite poly cone for robust low-frequency performance. Gold-plated binding posts and a cloth snap-fit grille ensure both reliability and aesthetics.
