Spa Happy, I have done 3 shows since the 400 series came out, the only advice I can give you is to make sure you fill the 470. It rocks. And the stereo will blow people away. I have another show going this weekend too. Best of luck!
That's a positive I forgot. There are speakers set into the shell. No more of that pop-up stuff. I didn't hear them but it doesn't make sense for them to put cheapos in. Are there external jacks to connect a home stereo to the spa speakers?
Why is one end higher, for the waterfalls? It's a pretty spa. Terminator
