Old thread, but here is what I know. I believe Avant speakers were at one time made in Florida. As to the Canada connection, ie: Fairview Electronics in Toronto, that makes sense. Fairview had a lot of good brands that they sold. SOMA speakers, made in Scarborough ON, were also a brand that they promoted. I just took on a pair of Avants, not sure of the model yet, 3-ways, and the woofers needing surrounds appear to be Philips, 10", heavy magnets on these. Cabinets are going to need lots of love on the walnut veneer.
What amazes me, and also causes confusion in our circle, is the number of speakers beginning with 'A'! I have had Advent, Avid, (Reynolds) Advance, Avanti (Canadian Audio-Logic), just saw a pair of French Avance, as well as 3A (Art & Audio Applique?). Then we have Acoustic Research, Audiosphere Research (Canadian, many variations), Accusound, Accuphase, Acoustech Labs (Pro Linear from Vancouver, BC), and many, many others.
I will play with the Avant speakers I just got and try to get them back to their glory, including sanding and oiling the cabinets, and get back to everyone on their performance (so far, on low volume, very good!).
