In reply to a couple of points raised in the thread.

I have no issues with the current sound of my speakers.

I am aware of the shape of the current plinth and that the shape could be for acoustic reasons and would take that into account when building the extended plinth.

My reason for this idea was more to do with the height of the speakers in relationship to my 65in TV that sits in between them, and no I couldn't have them sloping, and as mentioned earlier DC Tannoy's are as far as I am concerned, the least directionally worried speakers.

If I get an improvement in sound as a bonus I will let you know.


But this could be some time in the future as I am half way through my house purchase, then I have to build my new garage/workshop/man den, and then I can make the plinths.
