Overview
The Adamson IS118 is the companion subwoofer to the IS7. A lightweight, long excursion 18 inch ND18-S Kevlar neodymium driver sits in an efficient front loaded enclosure, giving clean low end from 35 Hz to 100 Hz.
Its rigging matches the IS7, so it can fly in the same array with a simple adapter frame or sit on the floor. A dual grille means it looks the same when arranged in cardioid mode, which is handy in churches, theatres and venues where the subs are on show.

Forefront Tip
If the subs sit near the stage, set up a cardioid group with one reversed cabinet per stack. It pulls low end off the stage and the band will thank you, and because of the dual grille the reversed box looks the same as the rest from the audience.
