We have a Bose with five cube speakers, wall mounted, wiring in the walls. We need to replace it and prefer a non-Bose product. We are looking for a minimum number of wires. One recommendation is to buy a Bluesound Pulse soundbar, perhaps with a wireless sub-woofer, perhaps with two wireless back speakers. Another recommendation to buy a Sennheiser soundbar. Both of these are in the mid to high price range, said to be good for music listening as well as surround-sound-like for movie watching. Does anyone have any experience with these? Also, if we go with another 5 speakers, does anyone know whether we can use the existing -n-wall wiring we have for the Bose speakers?
