Hi,
I can't be sure. But a different tweeter with different response characteristics can radically change the tonal balance of a speaker.
This is all kind of speculation, because I've neither seen nor heard the Michaura speaker, so I take Ian C. at his word when he told me that it was "quite a different speaker" from the M22ti's. You cannot assume that a speaker designed under an OEM contract will bear any tonal resemblance at all to a manufacturer's premier brand, even if the drivers have a superficial resemblance to those used in other models.
Regards,
