DJ Extraordinaire
Something you fail to realize Steve.The K8 and K10 are very robust speakers. The issue with them is they have wide dispersion horns, which won't carry very far outdoors (same issue with your 802s). A 12" or 15" box with a dispersion around 75 degrees will be a good compromise to cover both a dance are and to reach back enough for general use. If the area to cover isn't that large (150 people says it's fairly big), then the smaller tops might work.
My 802s are not fed Full Range signals. Mids and lHighs are all they get (In a two way setup) or Mids OR Highs (In a 3 way setup)
They are powered by their own individual amp not shared power. Makes a big difference.
My 802 are usually about 4 feet higher than the height most DJs place their speakers. This gives for more dispersion.
They do not have that shrill sound I hear from a lot of those speakers.
I do not use my 802s outside. I know better.
