EDIT: The testing methodology was updated to use a non-reactive load (water heater elements).
I purchased 10 of these (Camco 6000w 240v low watt density):

Each was measured and the resistance was either 9.9 or 10ohms, so with 5 wired in parallel for each channel the resistance came to almost exactly 2.0ohm. 2ohm stereo or a single 4ohm load utilizing all 10 can easily be wired. Utilizing just four of these elements per channel I can wire two 4ohm loads ((2) in parallel + (2) in a series).
1. For the CEA-2010 burst tests I use REW as the signal generator and a Rigol DS1054Z oscilloscope with a 10x probe to measure Vpp. The amps are pushed as far as possible while still being able to produce a clean CEA-2010 wave form.
2. The second test is 12 seconds in duration at 20hz at maximum clean output.
** What these tests do not reveal! **
- Efficiency (I'm not measuring current draw from the wall)
** These tests below were performed with my (8) sealed 21" drivers as the load. I no longer have these amps so I can't re-test with the latest method **
