Do you have Calisto? It is classic and it looks great in italic. Or are you thinking something more scripty? Karen

just take the two front (left/right) speaker outputs from your amp(stereo) and hook them up to the speaker selector input, from the selector go to each set of speakers you want to control(I have L.V RM/FAMILY RM/GARAGE),make sure the impedance protection is activated on the speaker selector(as you do not want to damage your amp).If you hook up your input off of the center channel you will get mostly vocals out of your set up(not good) .If you can you should try your set up with at least the center speaker the effect is most impressive with most movies!Good luck!

You might be talking more about the spacing itself but... Don't hire a handyman...posterboard or newspaper is your friend! Measure and cut out all your sizes, use painters tape to move them around until you get them just how you want it. Mark your pencil hole right on the paper and hammer through. You can even push the nail through just enough to make a slight dent in the wall and then remove the paper to add the nail if you want. I make mock ups of everything. My walls would look like swiss cheese if I didn't!

it is unlikely you are going to solve your problem on a forum like this...unless you are trained in electric and HVAC, best advice is to call an established reputable HVAC dealer to fix your issue, especially with low 40 temps inside your home. When I see threads like this, I always ask when was a routine PM last performed on your system. Anything mechanical has to be properly maintained. Breakdowns do occur, sometime they can be avoided with regular service especially with a system that is old. IMO
