I need to mount some 6kg speakers on a dot and dab wall. I have the following brackets: https://www.amazon.co.uk/suptek-SPM201-Wall-Mounted-Tightening-Surround/dp/B08116Q1PS

I have some Corefix fixings I was planning to use: https://www.screwfix.com/p/corefix-connect-metal-plastic-100-heavy-duty-dot-dab-wall-fixings-10mm-x-95mm-24-pack/344hg .

The wall is 12.5mm plasterboard. I don't know the exact size of the cavity, but when I was fitting some electrical back boxes, I remember I could only fit 25mm one as a 35mm was too deep.

Is there a better option (other than floor stands, as unfortunately I don't have the floor space for them)?
