3A Adagio Monitor
3A started in the 70s and had a large factory in Antibes on the French Riviera. They were often nicknamed as the "French JBL" and within a few years were established enough to make their own drivers.
They also claimed to have the largest anechoic chamber in Europe for testing their designs. That claim was certainly in tune with the owner's attitude!
These products were indeed often inspired by others, well enough manufactured to attract good reviews and were primarily sold in large retailers who were more interested in the fat margins than the most accurate sound...
Having said that, 3A still commands praise from a lot of owners, if the comments on various forums are to be trusted, and it seems that there are still quite a number of them still working. You can find a few for sale at www.hifi-antique.com (see photo).
3A did a lot of work on woofer servo control and active speakers, destined to the pro market.
I am personally quite interested by the Triphonique, an active subwoofer disguised as a coffee table paired with the 800 satellites, as well the Studio, an avatar of the Elipson 4040 or the Master 5 for the same reasons - see photos below.
Rumor has it that the company was reborn in Canada under the name Reference 3A. I am seeking confirmation before adding to the confusion.
