Hello, my name is Len and I'm new here and to audio equipment in general. My question is the following. I have a pair of the Klipsch sixes and was wondering if I could add a pair of passive floor standing speakers to my set up with a receiver? If so how do I go about wiring this? How do I control volume? Will I ruin my sixes? I'm lost and in need of guidance. I look forward to any help 🙏
