Hello Group- I'm totally new to this, and hopefully will be able to gain some knowledge by hanging around & reading, as well as soliciting some advice along the way. I just finished installing my Z5500 system, and am wondering about the volume level. Perhaps due to the size of the room (40x40), it seems that the volume is adequate, but not "impressive". I've only run it from the auxiliary input so far (via Ipod). I'm hoping once I get a PC hooked up to it with a decent sound card, I'll be able to adjust & fine tune the sound a bit more. IF I were to obtain additional satellite speakers to share the same outputs on the Subwoofer, how do you suppose that would affect the volume, and would it have a negative affect on the system? What options might I have to get that additonal volume, or am I just asking this system to do too much, considering the size of the room? Thanks!
