I just received my Paradigm Studio ADPs. I will be using them as SIDE speakers in a 7.1 set up. Studio 40s will be used as the rears (about 3-4 feet behind me). Now, should I keep the side speakers at ear level, on a speaker stand, like the rest of my set up? Or should I mount them around 5 1/2 feet above the ground, directly to my sides? Please let me know what would work best. Thank you.
