The baffles are mounted to the side brackets using six M6 flat-head bolts, secured with thumb nuts at the back of the side brackets, with rubber decouplers placed between the metal side walls and the baffles (the illustration is of our Duet15 but the procedure is the same)
The rubber decouplers we currently provide have adhesive on one side and should be carefully aligned and glued over the six holes on the front of the side walls. After they are attached, the six bolts on the baffles will pass through the decouplers and the holes in the side walls
We recommend first carefully positioning the baffle on the side brackets using only two bolts (bottom right and top left), and tightening them lightly to prevent the baffle from falling out of the side brackets
Thereafter, insert the remaining four bolts into the holes in the baffle, through the rubber decouplers, and into the holes in the side brackets
Once all six bolts are properly in place, tighten the thumb nuts as firmly as possible by hand
If you feel the need to use a wrench, do not over-tighten the bolts. The rubber decouplers should be only modestly compressed to ensure proper sonic performance of the speakers
