Hi, I own a small PT studio 10x8 with a high roof (small industrial unit). I have just purchased a play 3 and intend to add to this. My question is: should I add another play 3 at the opposite end or add a play 1 at each end and have a play 3 on the side. So 2 x play 3’s? Or 1 x play 3 + 2 x play 1’s? Thanks.
