IIRC (and I may not), Mark Levinson (the man, not the company) used Hartley woofers with Quads and a super tweeter in a very early assault on the loudspeaker SOTA. The system was highly regarded in many high-end circles and the Hartlley woofer was supposed to be the edge of the art in low end reproduction. FWIW.
Hartley speakers--anyone heard/heard of?
i recently found an old pair of hartley bookshelf speakers in a thrift store, and upon doing a bit of research found that they are one of the oldest manufacturers of speakers still in existence. yes, they are currently based out of wilmington, n.c. after their beginnings near london and subsequent moves to n.y. and n.j. they still manufacture their own drivers by hand, although they do not currently build finished speakers. i have to say that the midrange on these unassuming little speakers really surprised me with it's immediacy and detail (but then again i'm easily impressed :-) but i REALLY was impressed that they are still around, quietly crafting their product for all these years.
