I am finishing my basement with a home theater, large rec room, and workout room. I am going to have a Pioneer Sc35 in the theater and speakers in the rec room and and workout room for music only hooked up to the 2nd zone on the Sc 35. I will have one in wall volume control in the workout room with 2 speakers and one volume control in the rec room. Because of how large the rec room is I want to install 4 in ceiling speakers and have them all hooked up to the one volume control in the rec room. I believe the volume controls are made to be hooked up to 2 speakers so my question is..."If I double up the speakers running through the volume control, will there be a serious effect on the sound"? Keep in mind it will be for music only. I will be using 14guage speaker wire and either Polk or Speakercraft in ceiling speakers. I have not purchased the volume controls yet but will be getting a basic rotary style. Any help would be appreciated as I need to start this project next week!
