We've just purchased 2 x RCF 712's and combined with 1 Mackie 1501, we are covered and gave a great sound.
Previously thought we've tried Mackies, JBL and EV albeit their lower budget tops but by far, we believe that the RCF's blow them away.
Had a very good deal on them too. By purchasing the official bags, the front and rear panels zip away and hold against each other during use so the main body is and always has been protected.
The Mackie sub, great for what we use it for but it does weigh a lot...
