not sure yet if I've ruined it or played a blinder... But since acquiring the lovely gloss black KEF R series speakers, my pine cabinet just 'stuck out' too much.
So, I have just sanded it down, applied a ooat of primer and given it the first coat of gloss black paint.
I will give it a second coat tomorrow.
In case I end up with a streaky mess, I also bought a tin of gloss black spray paint which I will practice with first on the raised TV platform (as that will be covered by the TV anyway.
I decided to do this after yet another failed and lengthy shopping / searching expedition to find something commercial that met my needs. It's so important not to 'close in' the centre speaker and to have it angled up.
With a large TV and deep centre speaker the only way to do this is with a cabinet depth of at least 500mm, and probably nearer 600mm as in my case.
Really frustrating that you can't buy something like this professionally without spending thousands.
