General Application

Stage Monitor

A 2-way passive full range system in a vented dual angle stage monitor enclosure. Includes a 15 in woofer and a 1 in exit/44mm voice coil compression driver on a 90 x 45 constant directivity horn.

The SM155e extended bandwidth professional stage monitor offers steep and shallow floor angles for placement options. Presence control helps eliminate feedback. Dual NL4 connectors facilitate "daisy chaining" multiple monitors.
