Welcome to our forum.
I have a new HS Grandee with the SpAudio. In contrast to others, I'm not impressed. The CD player (a Memorex) that comes with it is of fairly low quality. I have tried an Ipod, but the output level does not seem high enough to drive the speakers. Using either the Ipod or the CD player, you have to play the unit at the highest volume to get any sound at all, particularly with the jets running. This causes constant clipping.Note that with the SpAudio, you are limitted to just changing volume from inside the hot tub at the secondary panel, and there is no indicator that you are correctly on the setting that affects volume. You just hit the buttons and hope that you got the right combination to make it work!You have to turn the cd player on from outside, and adjust its output and pick songs. Then it gets shut up in a very flimsy case. Given how expensive this option was, it is disappointing. I also would fault the comments that the sound quality is clear. Many of the high frequencies are absorbed/muffled by the water. I played REM's Monster last night and it was almost unrecognizable.Just my take on it. I have some doubts that my system is working correctly, since it is so awful. But given my experience, i would not recommend it.BearBath
but i went back in and correctly my problem after speaking with tech support.
