A milestone TW AUDiO development, the B18 is the result of countless customer requests for a subwoofer of this quality and flexibility. Combining tight control with a remarkably deep and distinctive rumble, the B18 features a symmetrical band pass design that delivers a consistent performance regardless whether vertical or horizontal, stacked vertically or side by side.

This includes the creation of directional sub arrays with partly reversed subwoofers. Facilitating the easy and inconspicuous wiring of directional bass clusters, the B18 even offers two speakON™ connectors on its front grille.

B18 Depth control.
