I suppose by definition satellites speakers are speakers that placed out there by itself. But in most case the only one to worry about are the 2 rear speakers; the others are usually connected in the same area where the equipments are located.
As for wire connections, usually two wires (like a lamp cord) from your equipment to the rear speakers.
i am looking at buying the Panasonic SC HT500 after reading your review. i can't understand if the speakers have wires that go all over the place, or if they don't have wires? are they "satellite speakers?" and if so, what does that mean? i'm sorry i'm rather clueless in this department, but i can't have wires going all over the place and want to put speakers in a few places of my apartment.
thanks for your help!
