Hartley Products Inc - one of the Ultimate European Loudspeaker Drivers ever made?

[tiefbassuebertr]

While clear up, I came across to an old speaker catalogue from Hartley Products Inc.
What about this brand? Are there even commercial products where inside this brand?
Thank you for tell about your sonic experiences.
Perhaps it could be "ALE/Goto" from Europe resp. US - go to find informations about this brand to
http://www.goodsoundclub.com/PDF/GOTO.pdf (scoll down) and
Who have heard drivers up to 100 kg from ALE/Goto - the most expensiv over the world

The big one is a classic "super woofer".

I guess someone is still making them.

Their spyder assembly is of note - old school.
No relationship to ALE/Goto afaik.

The big woofer was used by Mark Levinson in his QHD (?) system which was a pair of stacked Quad 63s a Decca ribbon and the Hartley 24" woofer... quite good actually as a system, but huge...

Btw, are you doing a survey of exotic speakers??

Yes, but only such, that currently in production and not obsolete.

H A Hartley was British. Started in 1927. As Hartley-Turner they sold the 215 an 8" (cone size) full range. Centre of cone was decoupled from the rest by a compliance. Shown in New York Audio Fair 1951, and sold thro to the early '60s I think. Expensive. Free air resonance about 35 Hz, but heavily damped due to al vc former. Xmax about 6.5mm. Claimed on-axis frequency response at 1 watt was within plus/minus 5db 40Hz to 20KHz mounted in a large OB, and at 4 watts, within plus/minus 10db 50Hz to 18KHz within a "boffle", an 18inch heavily damped non-resonant open back cube.
Max power 20 watts, Flux density 11,500 lines/sq.cm Alcomax II magnet 4 ohms only.
Eventually Hartley sold out and the firm moved to USA, where a different range was developed and sold, particularly big cone units, which are the ones you know.

BL spec is total rubbish:
24"

Have you by chance measured your drivers? My neighbor had the same drivers BTW
