Help deciding bass trap size and density

Hello all,

After going through a lot of expert advise and reading articles here and of course the available material, this is what I have decided for treating my room -

1. Broadband Panels for early reflection, rear wall and where ever need - 64kg/m3 rockwool, 4" thick with a 2" airgap.
2. Superchunk style triangular bass trap for the corners - 48kg/m3 rockwool, 28" face and 20" sides.

Since these are the only two rockwool slabs densities I can source locally, with no GFR values and easy on the pocket, can anyone suggest wether the dimensions are looking good or not according to the densities?

Someone suggested a much lower density for the superchunks, which makes me wonder if I should forget the superchunks and just make more of those broadband panels with 64kg/m3 rockwool to straddle the corners? Or make 6" panels for the corners with the 48kg/m3 rockwool?

Can someone help me decide better? Any help will be appreciated.

Thank you!
