Wireless speakers are definately not good sounding. Think of a Cordless Phone amplified...bad news... Now if you need speakers for a rear setup in a ht system, then in ceiling or wall is an alternative... you will need to have them wired though. If you are looking for simple second room sound, background music etc.. then on the non-audiophile end...wireless speakers would do the job... but not knock anyones socks off. To answer your origional question... does a wireless speaker exist... I dont know... Try Niles or Boston Acoustic... Niles makes quite a bit of in wall and custom application products... they might have something for you.. Sorry for the long winded approach, but wireless is usually useless...
