>>>I know plenty of speakers that don't need high current- that idea in the post above is an example of a common audio myth.
Not really, physics is still physics, even in audio. Size/efficiency/extension are entwine. If you wish to extend as low as the Magico do, and be as efficient as Wilson, you will have to have a huge enclosure. If you wish to be efficient (add a port), and not have a huge enclosure, you will have limited bass extension ( i.e. Wilson). Choose your poison. The problem is that in order to gain efficiency, many add a port which by definition limits the bass extension by doubling the bass roll off rate. Ports also introduces group delay and all sorts of other issues… Like I said, no free lunch. BTW, in Europe you see Magico pairing with Nagra and Zanden quite often.
