|16,100yen (one-set, around the 1970 in-the-early time)
The thin speaker system thinner and developed aiming
at Hi-Fi more.
It has a structure somewhat smaller than SL-7.
16cm cone type Woofer is carried in low-pass.
The cone paper which made the
high kraft pulp of the Young's modulus the entity is adopted as a cone, and also
in order to think musicality as important, while the principal components of the
musical instrument had gathered, the point was put also on the rich play of
compass, and the aluminum dome radiator is adopted.
In addition, the ferrite
magnet is adopted as a special polyurethane rubber edge, a damper with a
sufficient linearity, and a magnetic circuit.
In order to improve a
low-pass play, a 16cm pssiveradiator is adopted.
By oscillation of this
cone, a pssiveradiator is reverse in a phase, makes the bass which is a cone
type unit without a magnetic circuit, and came out to the backplane of the
Woofer unit, and is aiming at the modification of the bass play.
linearity which was excellent also in the large swing with adoption of a special
polyurethane rubber edge or a piano wire damper has been acquired.
horn type tweeter which aimed at high-efficiency-izing and a directive
modification is carried in the high region.
LC type of 12 dB/oct which
harnessed the transformer technology is adopted as a network part.
enclosure is using the high special plywood and particle board of a hardness, and the member which is a Japanese traditional-handicrafts article is attached.
There were two kinds, SL-5 which employed native wood Spinar's bark of a
tree efficiently, and SL-5W of white finish.
There was a table lamp only
for a foot type of aluminum finish as an option.
