Allegria
Pure listening pleasure....
The Allegria is a 3-way floor standing bass reflex speaker using
modular cabinet technology and new drivers developed for low distortion
and flat frequency response. The cabinets employ a very intricate
internal construction and each module is decoupled with resonance
control devices.
Sound Quality:
Sonics puts high emphasis on spatial presentation, neutrality,
resolution and dynamics. The Allegria's bass reproduction is clearly
defined, the mid-range is exceptionally open and natural, while the
high frequency range reveals new details, without any indication of
sharpness. Outstanding reproduction of micro details gives the Allegria
a warm, 3-dimensional presentation.
The Ribbon Tweeter:
The high resolution capacity for ribbon tweeter's has been acknowledged
for decades. However, ribbons could not match the dynamics and low
distortion of highly developed coil tweeter technology. New
developments in the field of materials and construction have overcome
these disadvantages. Its moving mass is only 35 mG, a tenth of the mass
of a 25mm dome tweeter, yet, the increased surface area over a
conventional tweeter results in an output of 98dB. The result is
increased output capacity while distortions are reduced to an
un-measurable level. This ribbon's output is so high that, unlike dome
tweeters, it is not the limiting component in the overall output of the
speaker.
Mid Range Driver:
Historically, listening trials and measurements show paper to be the
optimal material for mid-range drivers when transparency, dynamics and
neutrality are the goal. While similar results are obtainable with
specialized metal alloys, those drivers are less efficient and require
complicated crossovers. The Allegria midrange contains the latest
developments in paper cone technology. A damping coating is applied to
the back of the cone and Nextel, a ceramic based coating, is applied to
the front. This driver is linear up to 12 kHz but is crossed over at
2.35 kHz. so it operates in its most linear and distortion free region.
The result is a particularly fast mid-range with a distortion factor
reduced to an unmeasured level.
Woofer:
The bass region is handled by a metal cone woofer developed
specifically for the Allegria. Designed to be exceptionally stable, it
easily withstands high acceleration forces and has a cone shape that
eliminates resonance in its frequency range. This driver is capable of
enormous acoustic pressure without compression or distortion and
delivers well defined bass with exceptional clarity. Its speed and low
mass ensure high resolution even at low volumes.
Cabinets:
Due to its low price and easy machine-ability, MDF (medium density
fiberboard) has established itself as the primary material for speaker
enclosures. As for performance however, due to its weight and
flexibility, internal sound pressure turns the entire cabinet into a
high distortion speaker. To avoid this the Allegria is built from a mix
of 30mm birch plywood and 30mm HDF with elaborate dovetail joints at
optimal places. The unpleasant sound associated with MDF is avoided.
Woofer, mid-range and tweeter housings are decoupled to prevent
bleed-through. To maximize stereo imaging all cabinets have a minimal
front surface area. Up to 6 spikes can be mounted into the base
offering various coupling options.
Crossover:
Sonics possesses special know-how in the area of crossover design. As
part of a two-year research program all critical parameters were
computer simulated and measured. The best components (condensers,
coils, resistors, wiring, and plugs) were also tested and auditioned.
An optimal algorithm was developed for the Allegria and the final
configuration was determined through listening. Like other Sonics
models, we used our DC module, transitional filter and back EMF
damping. The technical advantages of our crossover are: linear
frequency, phase-locked coupling with the cabinet, high slope between
mid-range and tweeter for minimal acoustical interference and
exceptional slew rate. All this results in exemplary sound quality with
impressive rendition of soundstage width, depth and height, focus and
transparency. The speaker also presents a friendly load to enjoy with
both tube and low-wattage Class A amplifiers.
