For no apparent reason I decided to see if my old minisystem speakers would sound better than my center speaker(a cheap Kenwood). Since they are 6 ohms I decided to use both of them in series to give a 12 ohm load to the receiver. It wasn't easy because the speakers have built in wire so I had to twist the speakers wires around the 16 gauge going to the reciever(wouldn't have had enough wire otherwise). Now they sit right next to my TV and they actually sound better. Other than the fact that the localization on the TV is not quite perfect they are better in every way. Dialogue and sound effects have improved. Is there any reason not to use this technique?
