For my dummy load, I calculated the length of enamelled copper wire (heavy gauge) to give me 2, 4 and 8 ohms. I then wrapped it around a simple wooden former made of 38mm square timber, with tappings at the 2 and 4 ohm points.

The resultant "contraption" was mounted on the workshop wall above the bench.

Largest amp tested was an FPC10000; the dummy load was only slightly warm, but very clearly audible. As a bonus, if you want to monitor the signal waveform, just lean the probe on the wooden frame.
