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.
They were the 500 watt version (SUB-1D-500R) and not bridged. There was only 1 sub and it was hooked up in the correct location (SUB1 vs SUB2).
Brad,
If I can get my hands on another 3160 and test it and it comes in at 2 ohms, we'll pop a KASA in there. I appreciate the info.
On a side note, I like many of you have been installing these way before DSP amps came to the market. In the past, you could use virtually any amp with any subwoofer as long as you set frequencies where it made sense.
I understand the concept of DSP amps and why they are touted. However, speakers are speakers and haven't changed over the years. Why would DSP amps be so crucial now when they weren't in the past?
We had to deal with product shortages during Covid and used mismatched amps on a number of occasions. We have replaced amplifiers for existing in-wall solutions that weren't matching many times over the years. I understand the theory of DSPs and how they can optimize sound but is there any science to the claimed concept of "you must use our amplifier"?
