I had responsibility when I worked at GM, to run our very expensive automotive noises listening studio that had incredible acoustic features built in, like slat-helmholtz resonators, panel resonators to control low frequency modes, fiberglass reinforced ceramic ceiling tiles with dispersive reflective surfaces, rotate-able wall panels to change the RT in the room, etc. We ended up rarely using the built in subs in the room - because they excited the framework from which the ceramic panels were suspended like a drop ceiling. They buzzed. We worked for weeks on trying to eliminate the buzzes and as soon as we would fix it in one area, a different part of the framework would light up. Huge huge headache. That's the only part of the room structure that was not properly designed. As with any acoustics design project, the whole is only as good as the weakest link. In your design, I would be wary of the cable run tubing. Make sure it doesn't run by any noise sources. It's what we would call a 'flanking path' for airborne noise.
