The Ranger Paragon was rated 95 dB at 1W, 1m. The midrange and tweeter drivers by themselves were much higher. Even allowing for some drop-off with distance, your recollection of 82 dB rated efficiency seems too low. It also seems low for a horn-loaded speaker, in general.
It would be cleaner methodology to measure the SPL with one of the "other amplifiers" using the same power levels, power metering and SPL setup and equipment as with your amps. I hope you will consider doing this. As it is, you seem to be relying on past experience and recollections of what is "considered fairly accurate" to make you key point, instead of side-by-side measurements.
I am taking no position about your amps here, as I have no experience with them.
