I recently acquired a single QSC KSub and now trying to decide what tops I should match it with. This system will be used for my own family gatherings and backyard parties. Originally had a pair of behringer 15" tops with a single 18" behringer sub and it worked great for my purposes but was more of a pain in the ass to lug around and also took up too much space in my room. My plans were to downsize in the equipment but still keep a good sound system if possible. My thoughts were to just sell everything and purchase a pair of used QSC K12's since they provide pretty decent bass but I had a offer to trade my sub for the KSub so did that deal. It sounds pretty good and takes up less space, also easier to lug around when needed. Based on my needs, would you guys recommend 8, 10 or 12 tops? Any advice and help would be much appreciated.
