only 3 US passive loudspeaker makers could be found, and then calls them the best
what about Wilson?
I donāt think the writer looked vary hard. Iāll bet there are at least a dozen and probably more if you count all of the small local builders that donāt advertise
No Magico either. 
This guy lost me at the first sentence:
āIn the Bluetooth age, passive loudspeakers no longer represent the future of home audio.ā
PS Audio, Tekton, Owen Mills, Martin Logan, Acoustic Zen, Classic Audio, Devore, Eggleston, Macintosh, Genesis, Klipsch, Legacy, Ohm, Rockport, Soundlab, Vandersteen, YG.
And probably a dozen more.
In effect, article saying these speakers are not among the best made in USA, neither are Wilson and Magico
I read the article as a shallow sampling of a few domestic brands, nothing more.
Maybe I missed it but I donāt recall reading a claim that the covered brands were the only manufacturers of āpassiveā loudspeakers in the US.
You did not miss anything. It is not there
True, the article only referred to the best
True again, it is the marketing of the article as indicated in its link
Perhaps click bait
last line of the article is āpricelessāā¦
Give them enough space and drive them with quality amplification and you may not understand how a pair of floor-standing loudspeakers can disappear in a room like a pair of the worldās best bookshelf loudspeakers.
Wow. That IS priceless, now that you call it out.
I saw that also (in the browser tab). Canāt say I remember ever noticing that kind of disconnect before.
Please forgive me, this thread should be under Sick Humor
this article is simply an example of a litany of ultra superficial articles at the Gear Patrol web site, a condescending view of its audienceā¦click bait for advertisers
makes one wonder, however, how much seemingly more serious sources are themselves useless/unreliable
Update:
and then there is the litigious guiding hand āsynergisingā with financial thumbs on the scaleā¦
