Summary: When we added on to the house, I wired the addition for whole-house speakers. For general applications like bedroom and kitchen, I purchased speakers from AudioSource and Micca and have been pleasantly surprised with those purchases, especially considering they are usually less than half the cost of JBL, Polk, etc. I purchased these JBL hoping they would provide premium sound for a home-theater surround application.
Summary: We recently installed the SP6C's in our small Office/Computer/Work Room. Coupled them with a NuTone volume control, as the 'source' is two rooms away. For the most part we are running commercial free Live365 from our router to our Tivo and then through a home theater system for the bedroom. Once in awhile we might play a CD, or tape, or FM radio through the home theater source, to other rooms, but we mostly run the Live365.
Summary: Fantastic purchase. Not the most technical person in the world, but these installed so easily, and look great. Blend into my ceiling (used for rears in my home theater system). Can't beat the price.
Summary: it's pretty simple, you get what you pay for... no these won't be able to handle the loudest music with ease nor would i recommend them for home theatre surround... however, they work perfectly fine for ambient sound throughout the house... in all i bought 3 pair; one for the kitchen, the master bath, and the utility room... utilizing some volume switches and an additional receiver connected to zone 2 on my master receiver and i couldn't be happier...
