I don't think there is anything wrong with his review, sure placement is not ideal but the more important fact is that it is where his speakers are going. I want to know what it sounds like where I am putting it.... Sure I will move them 5 inches left or right or an extra few inches from the wall ect.. but I'm not redesigning my house to conform with where my speakers sound best, nor am I putting egg crates on my ceiling, and so on...
All reviews are what that person thinks when it comes to likes and dislikes, what sounds bright to me might be exactly what you want, they are a baseline to pay attention to when making your own decision...
Shady, you would seriously turn a speaker upside down? I guess it would be fine for a few models but some b&w, my evo2's, and a few others would have a hard time with that... I never tried it lol, most speakers have some sort of feet on the bottoms be it rubber rings, spikes, ect. It would look pretty silly with them sticking up, lol...
