[Onkyo shuts off with Forte II speakers]

I bought a pair of Forte II speakers last weekend.  I've been loving them!

But, I cranked the volume to 80 and the Onkyo TX NR656 receiver shut down. (45-50 is more common for me.)

Upon restarting it, error check speaker wires comes up.  All is fine again until I crank to 80.

I see no issues with the cables. 

 

Could this be a speaker problem?

@Iteachstem  I am looking for two of your K-31-K but with KLF-30s attached. 🙂

I keep reading that you've refinished, glued and re-horned, etc the KLF-30s that I've come across.
