How to mount heavy acoustic panels?

I am planning to buy Primacoustic broadband acoustic panels and their Fulltrap bass traps. But they are heavy mothers. Not the sorts i have seen mentioned in the threads on this forum which are 10-12lbs. Recomendations from their site is to use wall anchors capable of holding at least 55lbs. I will need to mount these panels on both my double wall made of gypsboard (the usual-2 gypsboards,metal stud filled with rockwool construction) and on beefed up brick wall which will be beefed up with some rockwool and 2 gypsboards on metal stud. Extreme care will be taken to properly finish these walls and now it looks like i will have to drill into them and possibly create problems. 1. Is it possible to mount such heavy panels on gypsboard wall at all? 2. How do i mount heavy acoustic panels on walls withot compromising isolation? :cry:

Maybe you could mount them on stands, instead of on the wall? That would also give you more flexibility, as you could move them if you needed to. - Stuart -

Thank you for your suggestion. I dont know if that is possible, considering. First, it wouldnt look tidy, plus i will have like 10 or 12 of those in CR. Imagine 12 panels on stands in control room. Second, it would take too much space. I think i will either have them on walls or i will not have them at all.

Does the manufacturer have any suggestions? They must have instructions available somewhere.

I would contact your builder or a contractor, or your local hardware store about heavy duty anchors... 55# sounds like a lot of weight even if it is shear loading and only a couple inches thick! You will need to be dead on with your screws/anchors that you anchor into the studs... Drywall isn't going to support a 55# load as far as I know. You might be able to place heavy duty screw eyes into the ceiling joists and hang the panels with picture wire which is available to hold a 55# load. Probably the best solution overall. Best of luck on your build.
