Just as the title states... I've finally decided on a speaker line, EV EKX's. Originally, I was going to go with two 12's over two 18's. Then I heard the 15's and was impressed with the bass they did provide in a small bar (75 person bar). I'll be using them for small bars like this, private parties, charity events, and eventually weddings. Trying to be budget minded and stretch the funds as far as I can. I haven't been able to hear the 12's in person, and not sure I will before I purchase them, unfortunately. Do I need two subs to start out with small events? Is one 18 between two 12's enough? I do like the sound clarity of the 12's a little more over the 15's... but I like to have bass for the songs that need it. I like the sound of the 18" subs, so I'm pretty set on those. I just want the best sounding and most useful tops I can get... and I understand sound preference is all over the place...
