Hi,
I've had the Paas speakers for almost 8 months. I use it primarily in the house. I tried to use it for an audition in this guys garage because I was a little too lazy to carry PA speakers. It was a two car garage so, it wasn't good at all. I think it brings out the sounds of the Pa4x.
It's just a little trickey (not difficult) connecting it to the keyboard. There is a rubber covering at the back of the keyboard that has to be moved from the contacts, so they mesh with the contacts at the back of the speakers.
****Make sure you connect the PAAS first before turning on the Pa4x. Otherwise they wont work.
