The professional studio monitor speaker system
developed a small control room and for the edit.
While inheriting the design
concept of model2401twin and model2402, in response to diversification and
high-quality-sound-izing of a music source, the sound which can respond to the
source of a broad genre is investigated.
25cm cone type Woofer TAD
TL-1102 is carried in low-pass.
The diaphragm laminates the special film to the natural pulp which performed
the aging treatment, and also is coating the special coating for braking
in the top layer.
Moreover, the AlNiCo-Magnet which can reduce secondary higher-harmonic distortion theoretically is used for a magnetic circuit, and the sensitivity fall by the demagnetization at the time of high power is also low suppressed by performing the design which has a margin also in the magnet operating point.
Furthermore, for a propagation stabilization of
driving force, when integral moulding of the yoke and plate of a magnetic
circuit is carried out and the upper center pole also carries out a screw stop
to a yoke with special casting, the synthetic of a magnetic circuit is improved
by about 4 times.
TAD TD-2002 of a driver unit and compact design horn
TAD TH-2002 are carried in the high region.
TD-2002 has adopted the 4.8cm aperture beryllium diaphragm of a light weight
and a high rigidity, and also has realized the linearity excellent in the
magnetic circuit of the AlNiCo-Magnet adoption which obtains the flux density
of about 20,000 Gauss. Moreover, the circular slit type which the phase
matching in a super-high region tends to perform is adopted as the phasing
plug which prevents disorder of the phase of an elastic wave. And a power-feeding
part is looked over again and it is considered as the direct power-feeding
terminal out of which the terminal on diaphragm assay comes directly out
of a back cover. Influence of internal alternating-current magnetic flux
or sound pressure was lessened by this, and the clear tone quality has
TH-2002 is the horn which performed the directive control with the wave-front
control technology, and the angle of beam spread is set as 60 degrees of
horizontals, and 30 degrees of perpendicularities in consideration for
small-scale monitor rooms. Furthermore, by adoption of the vertical asymmetry
horn by the APAXIAL (Asymmetrical Pattern, Axis&SFT Level) technique,
while acquiring a smooth output sound pressure property, the directive
control of the up-and-down orientation is performed positively. This suppressed
the influence of reflective from an enclosure top edge or a ceiling, and
the clear orientation has been obtained. Moreover, in order to suppress
a vibration peculiar to a horn, AFAST (Acoustical Filter Assisted System
Tuning) is adopted, and it absorbs by the vocal tube prepared in the horn
upper portion,A migration before and after the image by a pitch (pitch
of sound) is lost, and the articulation of play sound is raised.
As an option, there was an exclusive speaker table lamp in the
case of using model2251 as an object for listening.
The three-position type
of mounting which does not ask the flat nature of a ground plane was used for
exclusive speaker table-lamp CP-2251, and it has secured the stability.
Moreover, it constitutes from a thick wooden frame in the shape of a triangle so
that it may have an ill effect on a tone quality by neither a vibration nor
reflection of sound.
A front view or a vertex is used as a front view for a triangle-like bottom
face to a listening location, or tone control is possible for the point
supporting by the attached wooden pole etc.
According to the
CGR (Capacitive Gap Reduction) system of model2251, there was speaker cable TAD
TC-105 for exclusive use CGR-ized.
It connects two conductors of four cores
at a time, and is considered as + line and - line, and the attenuation is
reduced by careful selection of constituent material. Furthermore, the influence
of an unnecessary electric current is eliminated with the structure which took
the center earth wire in the center of the earth wire of a braid, and the
conductor of four cores to the sheath side.
