The SRX718S is a compact, high
power Subwoofer system containing a
2268H neodymium magnet, patented*
Differential Drive, 18" woofer in a
front-loaded, vented enclosure. The
enclosure is designed to present a
minimum frontal area. The system
offers complete input connection
flexibility for compatibility with a
variety of cabling schemes. A recessed,
external switch allows selection of
either contacts +1/-1 or +2/-2.
The SRX718S is equipped with a
top-mounted, threaded, 20 mm socket
that can receive the optional SS4-BK
pole. This adjustable height pole can
be used to Mount Speakers equipped
with standard 35 mm pole sockets and
weighing up to 50 kg (100 lb). The
threaded socket minimizes buzzing
and rattling and assures that the pole
will be secure and straight.
The enclosure is constructed of top
quality birch plywood, coated in JBL's
rugged DuraFlex? finish and is
heavily braced to maximize lowfrequency
performance. The attractive
CNC-machined, 16-gauge steel grille is
internally lined with acoustically
transparent foam to provide additional
driver protection and give a very
professional appearance. The rear of
the enclosure is fitted with T-nuts
which may be used to attach the
optional WK-4 caster kit.

James Bullough Lansing was born James Martini, 14 January 1902, in Macoupin County, Millwood Township, Illinois. His parents were Henry Martini, born in St. Louis, Missouri, and Grace Erbs Martini, born in Central City, Illinois. The elder Martini was a coal mining engineer, and his work required that the family moved about quite a bit during Lansing's early years. Lansing was the ninth of fourteen children, one of whom died in infancy. For a short time, Lansing lived with the Bullough family in Litchfield, Illinois. He later took their name when he changed his from Martini to Lansing.
Not much is known about Lansing's early days, and we are indebted to Bill Martin, one of three surviving brothers, for providing most of the information presented here. Lansing graduated the eighth grade at the Lawrence School in Springfield, Illinois. He also attended the Springfield, Illinois, High School. Later, he took courses in a small business college in Springfield.
As a young lad he was very interested in all things electrical and mechanical. At about the age of 10, he built a Leyden Jar which he used to play pranks on his playmates. He also constructed crystal sets, and at one time, probably about the age of 12 or so, built a small radio transmitter from scratch. The signals from this set were apparently strong enough to reach the Great Lakes Naval Station in Illinois; naval personnel determined the source of these signals and later supervised the timely dismantling of the young Lansing's radio transmitter.
For a while Lansing worked as an automotive mechanic, specializing in fine engine repair work. He attended an automotive school for mechanics in Detroit through the courtesy of the dealer he worked for in Springfield.
Lansing's mother died 1 November 1924 at the age of 56, and at that time Lansing left home. As best we can determine, he went directly to Salt Lake City. Mrs. Lansing, the former Glenna Peterson of Salt Lake City, tells of meeting Lansing in 1925 in that city. At the time he was working for a radio station as an engineer. In addition, he worked for the Baldwin loudspeaker company in Salt Lake City for a time. He also met his future business partner, Ken Decker, in Salt Lake City.
