The schematic below shows two dummy loads, built into one enclosure. With a speaker connected, the amplifier will see either a 4.3 or 7.4 ohm load while the attached speaker will receive less than about 1% of the output power. You can check the net load for yourself by following the basic electronics formulas. With a simple setup like this you can test at high …

16777. If you want to test an audio amplifier, here is a compact fan-cooled dummy load that can be used to provide any of the three commonly needed load impedances (4 Ω, 6 Ω or 8 Ω), with power rating varying from 125 W to 250 W. Interestingly, this dummy load can be made using readily available and relativity low-cost parts.

A nice dummy load. I've been building audio amplifiers for years. And until now I've always used just a bare wirewound resistor with some banana plugs as a test load. Well, no longer! I now have a very nice dummy load: It's a simple thing, really, but I thought others might get some inspiration and/or at least be interested in the sources for ...

Re: Dummy load for audio amplifier. As mentioned you want a non reactive dummy load, this is the way it's been done for years, you want to measure the performance of the amp not how a speaker loads the amp. High wattage dummy load resistors are fairly expensive but there happens to be a cheap alternative.
How to Build a Big Dummy Load. - Professional Audio Training
https://www.prosoundtraining.com/2010/03/11/big-dummy-load/
Amplifier testing requires a load that can dissipate the power generated by the amplifier, preferably one that does not produce sound. Some very creative dummy loads have been discussed on the SynAudCon listserv. I combined a few of the ideas and fabricated a load that should be able to handle about any commercially available audio amplifier.

Dummy load for audio amp, non inductive resistor necessary?
https://www.antiqueradios.com/forums/viewtopic.php?t=74373
Location: Minneapolis, MN USA. Gathering parts for a bench test speaker. This one will get built. Universal output xmfr, choke and resistors for field coil, etc. To include 8 ohm 50 watt dummy load for silent testing of audio stages or alignment (yes, I often watch AVC instead of AC on speaker). Tough to find non inductive resistor that's big enough, or cheap enough, and in stock.

200W 4ohm Aluminium Shell Braking Resistor Resistance Dummy Load for Audio | eBay. Tolerance +-5%, 40W without heat sink. I mount a pair back to back and the speaker plug is connected directly to wire lead, for very quick manual switching between the speaker and dummy. If your amp has gNFB, it's probably ok without a load, because gNFB has to ...
