Triad Siver Dolby Atmos Height Module: set of 6

Triad propriety Dolby Atmos licensed Height Modules - Silver. Consisting of a suite of 6 upward-firing speakers for use with 3-D audio (Atmos, Auto, DTS). Use for installations where the ceiling is too low for conventional in-ceiling speakers or for situations where wiring into the ceiling is too complex. Speakers each have 4 x 3" nomybium drivers that fire upward and are reflected down to the listening positions. Typical installation is 6 units: 2 front, 2 center and two rear. Finish is black pebble. Packaged 2 per box at 25 pounds. Speakers are 7 months old are are in great shape. I am moving to a new house that allows me to have a much larger theater and has access to the ceiling for wiring. Please note that the speakers are packed 2/box, so shipping is THREE boxes as described below. Recommended minimum power is 50 watts per channel. Frequency response is 130-20k Hz.
