Additional information, my set SAVA10 fronts each have a "full range driver" and a subwoofer in the right speaker. Each of the fronts also have an angled "full range" which create the illusion of a center channel, and believe me, it works, you can hear the sound coming from the center as if there was actually a speaker there. If you connect your TV to them you don't have to worry to turn them on and off, they go on stand by after 5 minutes with no signal. Left and right speakers are connected with a ribbon about 12 feet long, no other connections. Rears are connected with standard speaker wire. If you are interested in the manual, I am positive I have it somewhere, I am sure that it has been tucked away in a drawer for about 25 or 30 years. I don't know if it covers the larger sets, but if you send me a PM and tell me which SAVA is yours I'll check if it is covered and send it to you. Just tell me the model and your e-mail.
