Nice.
Why didn't you make them mirrored layout to eachother?
If on one wall the tweeter will be in front of the woofer and on the other wall the woofer will be in front of the tweeter -if I'm looking at the pic right.
Probably not a 'real world' issue, but still... seems kinda odd to me?
Next you'll have to build up an angled mini Alpha cabinet! hehe
I could use a pair of those for rear surrounds. heh
I know they'd be HEAVY for wall hanging, BUT... maybe hanging 'em on the wall and them placing say a 1.5" MDF veneered or black painted sheet under them reaching the floor would take the weight off of them without having to actually build some big stand for raised up mini- Alphas.
That'd let you have the mini-Alphas up high and angled down right at you to rather than aiming straight out and just the bottom of the line being within seated earshot.
Just a thought. Not to drift too far off from your surround pics.
