TAD started in 1975 (Technical Audio Devices)The
high-end speaker system developed as an ultimate home youth speaker which
responds to all environments, such as DVD-Audio and a play of a high-resolution
format like SACD, from the conventional audio play.
Speaker engineer who played an active part in KEF or Infinity It was developed
focusing on Mr. Andrew Jones by the R&D development block in the United
States, the Pioneer TAD development team, and the international engineer
team by northeast Pioneer. Moreover, the Japanese TAD development team
took charge of the speaker unit, Andrew Jones took charge of the total
coordination and the speaker system, and they were developed.
Two 25cm cone type Woofers are carried in
low-pass, and the 20cm cone type Woofer is carried in inside low-pass.
newly developed OFGMS (Optimized Field Geometry Magnet Structure) magnetic
circuit is adopted as the magnetic circuit of a Woofer and a mid bus. In order
to cancel the nonlinear component by the magnetic circuit which remains slightly
in the conventional short voice coil type magnetic circuit, flux density in a
magnetic circuit is made uniform by preparing a slit in the plate located in the
outside of a voice coil.
As a mid-high range and an object for high
regions, the CST coaxial unit (16cm and 3.5cm) is carried.
In the CST
(Coherent Source Transducer) driver, it has a structure which has arranged the
mid range cone designed by the optimal form in the director part in the
directive control of a tweeter. According to this structure, the phase of a
driver and the response problem of an axial gap are solved conventionally.
Moreover, axial symmetry is reproduced in the same sound balance in every
orientation from the hub of CST over a wide band by making the phase of a
tweeter and a mid range the same.
Moreover, the beryllium currently used
also for TAD for pros is adopted as a diaphragm. The play precision is raised,
while realizing a high rigidity and an internal loss to the extent that it does
not think with a metals by join of particles and driving away a diaphragm
vibration of a drive unit to an audible play out-of-band by using the
vapor-depositing method for a fabrication.
The SILENT enclosure
(Structurally Inert Laminated Enclosure Technology) is adopted as the enclosure.
The structure made from the Birch (birch) plywood layer processed into each
exceeding 50 is adopted, and even as for the part, the design is strictly
carried out to one form so that the stationary wave in a cabinet may not occur.
Thereby, since it does not have a joint of a cabinet, it has a structure which
does not produce the excessive oscillation by the reaction force or sound
pressure of a Woofer easily, either.
Moreover, it is attached so that the
International-Organization-for-Standardization(Isolation) Drive technology may
be introduced, and the speaker upper portion which has arranged CST may be
separated from the speaker lower which is an enclosure for basses and the CST
itself may intercept an oscillation from a top enclosure. It dissociates from
the unnecessary oscillation which this emits with a woofer, or a vibration of a
cabinet completely, and the capacity of the CST driver is pulled out.
