This is a situation where a client moved into a home with existing gear. We had never had issues with 4 ohm loads with other in-wall installs so we tried the Episode.
I've had many times where 4 ohm speakers test at 3.2-3.5 but 2 ohms seems too low. Before I throw a KASA on it, I want to try to test another 3160 to see if it also shows something in the 2 ohm range as I don't want to blow it up as well.
This is a scenario with:
Plenty of ventilation.
DSP: I think we set it to flat with frequency adjustments as the stock DSPs on the Episode offerings are limited and don't match a 3 X 6.5" set-up. I'd have to check with the guys.
Thanks for the feedback
Still need to know which Episode amplifiers were used.
Were the Episode amplifiers in bridged/mono mode? If so, it's likely that the failures were caused by low impedance, since the bridged amplifier will react to the impedance as if it's 1/2 of the real value.
Hopefully, the amps weren't the EA-DYN-2D-200 because the spec sheet shows "Bridged Power Output, All Channels Driven- N/A" and the EA-RSP-2D-200 spec sheet shows "Minimum impedence- 1 ohm for this one and 2 Ohms for the other multi-channel amps, but there's nothing about Stereo or Bridged Mono mode. Tech support confirmed that the spec sheet should have made this distinction and that none of these amplifiers should be driving a 4 Ohm load.
