Goldenear Triton One.R - can it be driven with low power tube amp?

Stereophile’s Nov 2019 review of the Triton One.r has a few differences from the Keith Howard review.
Measurements indicate that the impedance between the critical 80 to 200 hz range is between 4.1 and 5 ohms. And at the 80 Hz crossover approximately half the power is being delivered by the internal amp.
Speaker sensitivity is 92 db. So about 1/2 watt at 80 Hz should get you to that loudness level.
Manufacturer recommends amps that have a range of 20 watts to 650 watts. 
From these measurements, the manufacturer recommendation, and my listening test, I have no qualms about using a high quality SET of at least that power level, that is spec’d for 4 ohm performance.

One caveat to my discussion:
My listening “test” was brief - just a few hours.  Perhaps long term listening would lead to different conclusions. At any rate, were I to replace my ss amps with low power (not fleawatt) tube power amp(s), I would probably favore something greater than 25 watts, and would have to do some longer term listening with the new amp(s).

The supposition is not the reported test bench measurements of two published reviews.  My use of the term refers to reaching a conclusion based on those measurements without the benefit of any listening experiences with speaker and amplifier to confirm an assumption (Lower power tube amplifiers are insufficient to drive the Tritons).

It makes little sense to ignore the listening accounts of cakids and those mentioned regarding Sandy Gross (who plays the 'mere' role as the Tritons designer and also owns a pair for personal use). Perhaps these are inconvenient data points. Anyway, certainly two different viewpoints presented in this thread.

cakids OP
Measurements indicate that the impedance between the critical 80 to 200 hz range is between 4.1 and 5 ohms.

Cakids, you need to understand measurements a little more, Keith Howard’s are the EPDR measurements (combined impedance and - phase angle) That the amp will see.

Goldenear Triton One.R:  Review LAB Tests: by KEITH HOWARD
We measured a minimum modulus of 2.9ohm and a minimum EPDR of 1.3ohm at 92Hz, with further dips to 1.6ohm at 219Hz and 2.0ohm at 584Hz.
So the One.R is a tough loudspeaker to drive, despite its powered bass section.

This is what the amp sees, not just the impedance, common stop going round in circles.

Georgehifi,
You are correct. I have limited technical understanding of EPDR. I understand that a loudspeaker is not a resistive load. It is reactive and the reactance varies with frequency, as the phase angle varies with frequency. And the phase angle is the sine wave angular offset between the voltage and the current waveforms at the given frequency. I have no idea how to calculate EPDR, however.
Nevertheless, using the data from KH, can I assume that the amplifier current draw at 92 Hz will be approximately equivalent to the current draw, for the same signal (voltage) level, into a purely resistive load of 1.30 ohms?Just trying to understand these measurements a little better. I think I have already determined how to select an amplifier for these particular loudspeakers.

Charles, George, and other contributors,
Thanks for your inputs. They were informative and useful.
