I must say that from my listening experiences and subsequent aid in setting up a past friend's Mini's,the lower registers were absolutely "amazing"(and this from a sealed box)!This, in a room of about 12.5x21 or so feet....I assume the partnering equipment,which was SOTA added to the great experience.....Still,though a small-ish and sealed enclosure,the speaker dug "deep" and with superb precision at any frequency asked for.They definitely sounded BIG!!...Orchestral music at high volume was a cinch for this set-up.
There was a small group of audiophiles who nit picked this set up,but I firmly believe it was more of a rationalization due to the design getting so much good press,than anything else.
Though my final point might seem inconsequential,I LOVED the "look" of the MINI much more than Magico's newer models(I realize this is just me)as it was supremely attractive!
Best to all
