I was wonder dos anybody had a chance to compare the classic
Klipschorn with the sound of the 50's JBL Hartsfield ?
I would expect that the two speakers would sound very similar
do to the cabinet
design however the JBL drivers would probably have way different sound ?
.............................................................................................................
From Lansing Heritage-
The Hartsfield design was considered unique enough that a patent was
issued in 1957.
While there had been some criticism of the Klipschorn in its use of mass
market drive units and an insufficiently rigid cabinet, there would be
no such compromises with the Hartsfield.
The Hartsfield would incorporate the highest quality drivers in JBL's
inventory - the 085 kit consisting of the 150-4C bass driver and the 375
high frequency compression driver.
Both units had been originally designed for professional use
in theatre speakers.
The 150-4C used the same magnet and basket as the earlier D130 and
130A but added an extension to the outer rim.
This allowed the installation of a steep-angled, straight-sided cone
compared to the curvilinear cone in the earlier units. This cone design
provided added strength to accommodate horn loading of the driver.
The 375 had just been introduced and was developing a reputation
as the finest high frequency driver available.
It was unique in its use of a 4" diaphragm and 2" throat exit.
he 4" diaphragm and voice coil allowed for unparalleled output and
the large throat resulted in minimal distortion.
This driver was combined with a brand new H-5039 exponential horn
and "Koustical Lens" developed by Bart Locanthi. It was crossed over at 500hz
using the N-500 dividing network.
The cabinet for the Hartsfield used inordinately heavy stock for its
construction. It was comprehensively braced to result in an extremely
solid and rigid enclosure. A single speaker weighed over 250 pounds.
The final system was a sonic and visual powerhouse.
............................................................................................................
Do the 1957 and the 1964 models sound different from each other?
hey both look beautiful and similar, but I haven't personally heard
either one.

More information. If your interested in purchasing a set of Hartsfield cabinets,
there is a company just a few miles from my home that builds some of the
finest cabinets that I have ever seen.
They are expensive, but when you consider the time it takes to build
a high quality cabinet of this complexity it may well be worth it.
Hartsfield in Walnut are $3,500 a pair
Hartsfield in Rosewood are $4,500 a pair
These are temporarily not available,
but if you contact Classic Audio I am sure they can provide you
with additional information.
