The VERA S17i is a compact, flyable install subwoofer in a symmetrically vented enclosure, equipped with one 18” long excursion driver.

The specifically developed integrated rigging hardware allows a tightly screwed installation for perfect integration into VERA20i arrays with nearly invisible rigging parts, without the use of expensive locking pins and additional frames.

The fully symmetrical design of the rigging also allows to set up cardioid sub arrays with mechanically reversed enclosures. There is also the possibility to mount an optional front grill to the rear side of the enclosure giving a seamless look of the entire array.

The two recessed panels with screw terminals - one on the top and one on the bottom of the enclosure - allows for the signal connection between cabinets to be hidden. There are also installer options of plates with speakON™, cable gland and blanking plates available.
