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. There is a small crease in just one of the "faux grills".  No internal or performance impact. The cost os for ALL SIX SPEAKERS.
