Welcome to our forum.
I am real picky about Audio Quality, and I was less than impressed with the Spaudio with the transducers only. It was very different than other systems, it had no speakers to see or worry about, it enveloped you in the music, and it was integrated into the spa, the control system, the remote and the spa experience in a way that made it great. I had one for a year or two. The high-frequency notes were just a bit lacking. Then they offered the external speakers - and I became a fan again!! Great booming bass which you can feel right in the water, and now nice crisp mids and highs. Also, you can put the external speakers next to the tub, close to the tub, or in another part of the yard and you can control them separately from the transducers so you can enjoy music in the yard even when you are not using the tub. Tres cool.I don't mess with the CD deck. It's fine if you have a bunch of CD, or if you want to burn all your favorites onto CD because it will play MP3 format, but I use the Icast system to link my Iphone/ Ipod to the tub without wires. 8-)
Does the Icast come with the ~$1800ish spaaudio or is it another add on and if so what price range. Are the external speakers a 08 new addition to the transducers or an add on too.
Does the Vista have stronger jets over the Envoy because it has bigger pumps?
Differences:Redesigned spa side control panelRedesigned Pillows L.E.D. lights under pillows
The aux panel and pillows were changed in '07 and the under pillow lights are new for '08. The '08 Envoy will also have the new circ pump which runs on around 28 watts compared to about 68 watts for the '07. The '08 also has the all vertical cabinet. Can't think of anything else right now.
