We are offering as an alternative to spa stereos more of a outdoor sound system a denon receiver , CD/DVD player and 4 Yamaha outdoor speakers with a Sun cast garden cart to house the equipment in at 699.00 I think it offers far more value than any spa sound system as for the speakers we also offer Jamos which I feel are the best built of any outdoor speaker and have the best mounting hardware , the Yamaha's offer great value and I think are on a par with the Bose outdoor line.
