In response to your question, you are not hurting your speakers in the current setup, but you might be hurting your amplifier. Your amp sends out power over two cables to the + terminal, and the wire is shorted out when it gets there, its like connecting two wires together at the end. Could cause some type of mismatch or something if the wires are not exactly the same or whatever. Not a big risk so don't worry too much.
I am Not hurting anything right ??
I have a pair of Sonus Faber Concertinos that have bi wire posts. I have Bi wire Cable but have told NOT to Bi wire these Speakers. so I left the jumpers on the back and pluged in the cable as normal(standard bi wire configuration). Speakers sound great. But am I running any risk as to damaging the speakers?
