Grand Veena is a tall, slender tower housing five seamlessly
integrated unique drivers. The front baffle is tilted back
at a critical angle and the drivers are positioned precisely
for correct time alignment and sound wave propagation. The
multi chamber cabinet provides isolation to avoid interference
between the drivers operating at different frequency ranges.
Achieving
a coherent phase response has always been an utmost priority
for us and a design criterion with all our
loudspeakers. Carefully assembling the drivers with correct
parameters and choosing a more direct signal-path design
option, along with critical placement of the perfectly pair
matched drivers allows us to achieve this goal with our
Grand Veena. They project harmonically rich, clear and expansive
soundstage images and offer fatigueless extended listening
sessions.
Our
own hand-built 7" (170 mm.) main driver is hyper-exponentially
shaped and covers a wide range of the music evenly. Utilising
advanced materials and techniques the driver is designed
to not require crossovers and it is coupled directly to
the amplifier. The potentially harmful effects of crossover
components are removed from the path so the musical signal
arrives at the driver uninterrupted and intact. Every tiny
musical detail is tracked precisely and immediately.
Two
powerful 8" (21mm.) long excursion bass drivers are
used for extended low frequencies. Very stiff and light
cones of Fibreglass and Kevlar in honeycomb construction
are used to eliminate driver break-up modes. Rigid cast
metal driver frames are used to ensure mechanical integrity.
A unique acoustic device is constructed internally to absorb
excess pressure generated by the enclosure's standing waves
to avoid interference with the driver's motion. With only
a quasi-second order low-pass filter, low frequencies are
tuned to extend flatly down to 36Hz. while significant information
is still realised at even very low 20Hz.
A
very accurate high frequency driver with an optimally shaped
silk dome diaphragm and a low frequency resonance at just
590Hz. has been chosen. It integrates seamlessly with the
direct-coupled main driver. With a low mass voice coil and
a copper Faraday-Ring in the motor it is very well behaved
even at very loud volume levels. Simply connected with just
a capacitor as the high-pass filter to protect it from low
frequencies, it projects a smooth, detailed and spacious
treble.
An
unusual design feature of Grand Veena is the very special
ultra high frequency exciter by Murata Co. It is a 12mm.
diameter ceramic dome unit, which radiates in spherical
motion unlike the conventional piston motion of all others.
The very fine ceramic dome actually expands and contracts
dispersingextreme high frequencies from above 20 kHz to
about 100 kHz. to a very wide acoustic field. Although its'
presence is not easily detectable with conventional means,
it promotes better perception of a spacious soundscape and
surprisingly better definition at even lower frequencies
than its' actual operating range.
