Just assembled a pair of storage towers and am thinking about placing QS8's on top of them.
I will be cutting holes in the top of each before I do.
I've left a BD size opening between the top of the tower and the top shelf and I have sloped the spare shelf on top of this in the hopes of assisting the reflected sound but am left wondering what angle to you use on the sloped shelf.
Is there an ideal angle for this application?
The QS8's will be 90° in a 7.1 channel room, the bottom of the QS8 will be at 51" and the front of the angled shelf at 45".

I spend a lot of time trying to find a way to save it.
