The book shelf type speaker system of Tempest
The thing of the same type as LS4 is adopted as a unit and a
network, a small heil driver is adopted as a high region, and a 25cm corn type
Woofer and a 25cm passive radiator are adopted as low-pass.
accordion pleats made from Teflon are placed into the powerful magnetic field,
and the small heil driver has the structure where the element (electric
conduction belt) was embedded on the side of each pleat of a pleat.
signal is impressed to this element, current will flow, by motion of a pleat,
air is compressed and sound is emitted to space.
In order that a voice coil
may emit sound to space directly by this operation, the outstanding dumping
characteristic and low distortion are realized.
The 25cm corn type
Woofer is adopted as low-pass, and the low-pass play is improved by carrying a
25cm passive radiator in the rear surface of a Woofer.
The network of 18
dB/oct is used for the crossover of a Woofer, and it can carry out continuation
variable [ of the inside loud-sound increase and decrease beyond the crossing
point which is 2.4kHz ] according to the room.
