What's the dispersion angle on the RCF? Maybe I am missing something, (I checked their site and didn't seem to find it)... Dispersion angles for outdoors events are important for me... I don't want to hijack this thread, but moreover offer some advice... Anyways, my 2 cents: Have you ever noticed that the most common outdoor speaker used for large outdoor venues is the Electro-voice SX300PI and the SX300PIX? You will find these all over the world installed in venue's outdoors. They are used in almost EVERY application where outdoor sound is needed.
These cabinets are all weatherproof and work extremely well outdoors due to the constant 65X65 degree dispersion angle... you can even array them easily with little to no understanding of array technology or how it works for larger events.
I had 8 of these when I did outdoor events often. They were fabulous. They would sit out on tripods day/night through storms for 24 hour Relay for Life events... I never took them down even when it rained.
Kenny, I know they are out of your price range, but you can find them used sometimes and you could buy a nice quality used amplifier too... You could put the amp in a lightweight rolling type case and have the best of both worlds... I am trying to talk you out of thinking active for outdoor events. Yes active works and I use my SXA360's at outdoor events all year long and they work fabulous, but I miss my SX300PI's a ton for outdoor events. If you are planning to use these a lot for outdoors you will happy if you went the passive route for sure, especially all weather speakers.
I know it sounds like you have already made up your mind, and that is ok, but I wish someone would have intervened back about 15 years ago when I started those outdoor events and offer the same advice.. I had to find out the hard way what really worked well.
