I suggest you send Dr. Albert Von Schweikert an email. He is known to personally answer e-mails and phone calls from his customers. He is very helpful in setting-up speaker placement. Just let him know the dimensions of your room, and where your listening position is. I guess it would be beneficial to let him know where the chairs are and whatever furniture is in place too.
I too just brought my VR4jr home, but am rather restricted in its placement. But considering, they have imaged well and sound great with just 100 hours put in. I'm sure they'll only get better. Good luck.
