ZZ Top may be "the little ole band from Texas", but Watkins Stereo and Loudspeakers is the little but GIANT speaker manufacturer from my hometown of Kingsport, Tennessee that has been blowing audiophiles away since the 1970’s. Bill Watkins, Sr., is the engineering wizard behind the famous Watkins Dual-Drive Woofer which he licensed to Infinity Systems, the amazing WE-1 speaker (a Holy Grail find now in East Tennessee and Western North Carolina), and the current Watkins Generation 4 Bookshelf Speaker.
I believe this review summary should give you thought about checking out the $2,500 Watkins Generation 4 in your search:
"Had I auditioned the Gen Four blind behind a curtain and had to judge its value in the hierarchy of high-end audio I would have been happy to recommend it even at a price tag of $7k. Its asking price at a fraction of that is partly due to the direct sales model—there is no dealer markup. It simply sounds like a much more expensive speaker. And I should add that the Gen Four felt comfortable in the company of far more expensive components in the price range of $15k and upward."
