Lowther: the Bose of full range? OUCH! Seems a bit unfair -- whether you like the way Lowthers sound, they come closer to justifying their price than Bose do -- silver wire wound on both sides of the voice coil, some with alnico magnets, and a lot of hand work in production. Of course since there are so few of them made, the costs can't be amortised, so they are expensive. But they do enough of the things that speakers are supposed to do, and so well, that for some people its worth it.
Bose geets market share by advertising and by interior decorator type design, and only incidentally because of how they sound. I don't think anyone has ever accused Lowther of having marketing smarts or glamo looks.
