My right channel SDA-2 came back from a speaker shop who replaced the terminal posts with new connects. We had discovered one tweeter to be bad so I ordered 4, and replaced both tweeters in this speaker with the new RD-0149. When I connected it up, my AVR shut down whenever the music I was playing ramped up in volume. I took the speaker back to the shop to have them double check. All they did was to connect two terminals to the wires in the back. They checked ohms across the speaker terminals (3.8) and they will look into it further.
The AVR plays fine with this speaker disconnected (Yamaha DSP A1000 with separate amps for each channel - 7 of them)
Meanwhile anything I can do to determine if it's the Yamaha amp? (1) Connect another speaker (I have an old large Advent) to that channel? (2) switch the left SDA-2 to the right channel and see if that causes the amp to shut down?.(3) Install new tweeters in the remaining left speaker and see if that causes the amp to shut down?
