During a recent new home build, we were asked to install a system in a multipurpose room. The customer was already familiar with our work, and had experienced another install we completed using Axiom M80s. Based on this, clients criteria were:

-ability to play loud when called upon
-ability to have a large screen
-clean install with minimal items and clutter in the room

After some consultations, the decision was to go with Axiom on wall speakers with an in wall EP500 subwoofer. To hide the LCR channels, we opted for a 150” AT screen. To give the output required we went with OWM5s with a seperate outboard amplifier.

There was no option to build a false wall. The existing wall was ICF construction, so no clever way to use inwalls behind screen. Budget was of course important, as the customer did not want to spend money on items not directly related to their three goals above.

We went with a rail mounted screen aproach, where it would float in front of the OWM5s. The outcome was better than anticipated, as the picture floated off the front wall. This idea could be paired with bias lighting, though it wasnt requested for this setup.

We used finger jointed 5” (4.5” actual) pine jamb boards to take screws better and resist warping over time. We used 75lb rated EZ anchors to mount the L bracets and M5 T posts to the ICF wall. RTV silicone was used as well on the T posts to cement each to the wall surface as a backup. Screws into boards were pre-drilled, and a line level laser used. Pretty much mandatory for this work.

Hope this helps others consider an AT screen solution for their setups. Speaker grilles were removed prior to screen install.
