Obscure companies making excellent speakers?

Gershman Acoustics. Excellent reviews of the Sonograms I recently purchased. Eight inch driver goes down to 28hz!

Shelby + Kroll :-) Do a search and read through the site.
Tim Kroll has put together a great sounding speaker system.

I have recently bought a pair of Master One speakers. Master is a Dutch company that build wonderfull speakers. Not really sure if they are even sold out side of the Netherlands but when you have the option please give them some listen. There is really no reason for it but so far all the speakers I have owned are Dutch made as far as I can tell. Those brands were; Studio de Schop, Driade, Impulse and now Master.

My first hifi setup was purchased with paper route money in 1981. I bought a Technics receiver and TT with a pair of Genesis G1 two way loudspeakers (not the Genesis of today). The speaker manufacturer was out of New Hampshire and they were of the New England School of speaker engineering which was very similar to the BBC stuff coming out of England in the 70's. The company was doing well but made some mistakes and went belly up. The story can be found at this link, which is a web site that still sells parts for the Genesis speakers. A guy who worked for Genesis started his own company in order to manufacture parts for all the Genesis owners who were getting screwed out of their warranties. He makes his own line of speakers now.
