Just assembled a pair of storage towers and am thinking about placing QS8's on top of them.
http://www.amazon.ca/gp/aw/d/B001KW0BEC/ref=mp_s_a_1?qid=1361330173&sr=8-1&pi=SL75
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".

Are those units deep enough that the tweeters will tucked inside as well? I wouldn't recommend this mounting idea if they are.

I would mount above the top of the tower by extending the back of the shelf higher up or box the top "shelf" area in rather than cut holes in the top plate and mount the QS to the front face of the now boxed space.

It's not entirely clear, but if you cut a hole in the top of the storage tower for the bottom QS8 driver to fire through(what's "BD size"?), it should be as unrestricted as possible. A 45 degree shelf to reflect sound forward would be better than completely shutting off the bottom driver, but not as good as a free mounting allowing for dispersion in all directions.

If I do it they will sit ontop with a 5-3/4"worth of free space (was going to be the height of a bluray case) below the lower midrange. The top and tweeters will be unrestricted.
I do agree with mounting them properly but I really want to find the best position for them before hand. That and we might be moving this year and I'll want to take them with me when we do.
I had one tower already but couldn't find a pair to it. Found these online, sat on the idea for a while and couldn't resist.
I have a 4' doorway with no header between 90° and 110° . These stands will allow me some freedom during the next month or so while we figure it all out.
The spare factory shelf currently sits at about 10° but I had considered finding some black shelving to reach the ideal (in this scenario) angle.
I wasn't sure if it would help or hinder given the 5-3/4" allowance.

I bought my QS8s used, without mounting hardware, but I didn't want to drill holes, anyway, and there were pretty good places for them atop bookcases. I got two little kitchen-organizer racks and painted them black, and they sit on the open rails of those. They have about 4" of clearance at the bottom.

OK, I am getting the picture now, I think it should work quite nicely, 4" of clearance should be good enough, certainly worth a try as is before doing anything else.

Thats what I thought.
It'll be a shame to cut the hole but they are cheap enough to replace should it sound like crap.

Wish I had a QS8 v3 template.

Axiom can likely provide you with something.

I've seen other posts about QS8 locations, but nothing that says whether current owners have had better results with QS8'S flat against the wall, angled slightly toward the listener or at 90 degrees to the wall/facing the listener.
When I received my QS4's I had them up front as my mains ( I was exited too hear them and didn't have proper stands). They sounded better than the speakers my M80's replaced while facing me at ear height.
I've had the QS4's flat to the long wall as surrounds and front presence with similar results.
But, back to the first rant, what's your preference?
