Mirage M1 with SET amplifier

I know this big bipolar speakers has low sensivity ( about 83dB ) 
but impedance looks to be friendly ( 6-4 ohm )
What do You think , SET 300B amplifier ( 8 watt but very good transformators Tamura ) - i love this sound
can play with M1 in relatively small room ?

As you can see while needing watts >50w+) for their low efficiency, they don’t need an amp with brute current because they are a relatively easy drive load even for a PP tube.

Stereophile:
Overall, the M-1 should be relatively easy to drive, though the droop in the top octave would suggest that low-powered tube amplifiers should probably be best avoided.
This speaker will certainly give a pretty full measure of low bass, as can be seen from the in-room, spatially averaged, 1/3-octave response https://www.stereophile.com/images/archivesart/mirMir1fig2.jpg
All in all, I would agree with LA’s conclusion that the M-1 is an exceptionally well-balanced design.—John Atkinson

No, they need some grunt/power, a good push pull tube at >50watts with good output transformer low output impedance to control the bass, because they do go down quite low in frequency response.
