Ok so here is the situation I'm wanting to get a second SA-8, I currently have one in a L port box off about 600 watts. If i get another one, I will only be powering the both of them with a total of about 800 watts, so 400 a piece. Would I see better (louder) results from putting them both in a L port or in a T-line? I thought that with a t-line you were more efficient with smaller power? Correct me if Im wrong and thanks for the help.
