CH
Audio Design is dedicated to hand crafted works of art, we are not mass
produced audio
One job at a time, our
designs are unique and takes advantage of the best technologies available,
mixed with a great dose of experience and intuition.
We strive for the best .

Amplifiers
Coming soon, single ended amplifiers
|
With
an
Integrated amplifier we not only eliminate the cable run from a
pre-amplifier and all the potential problems and expenses associated
with them but also eliminate an extra two or more steps of
amplification, keeping the parts count to a bare minimum, only 3 tubes
in the signal path a voltage amplifier / driver and the output tubes,
only a phono stage for your turntable is needed inputs
provided
for CD, DVD, Tape
deck.
We never use any electrolytic capacitors in our designs,
anywhere.
Over rated choke input power supplies for better regulation and
current capability.

Multicellular
horns are formed by a cluster of smaller exponential horn cells,
available in different numbers according to their dispersion pattern,
each cell is small enough to avoid beaming in a large frequency range,
however they start beaming at the highest frequencies but thanks to the
circular pattern formed by the cluster of many individual cells the
coverage is quite uniform, together they form a large sector of a
sphere large enough to control directivity down to fairly low
frequencies. The cluster acts as one big horn at the lower frequencies.

Sculptures
Handcrafted works of art, a fully horn loaded speaker with 15" driver and compounded smooth round shapes, no
sharp corners, parallel walls or horn bends, mostly
free of resonance and reflections, is fired up to the ceiling, through a
straight passage of calculated shape, a mixture of straight horn, and tuned
pipe that could be used anywhere in your room or in the corners by
using the ceiling and adjacent walls as an extension of the horn.
The floor is often cramped with objects causing unwanted vibrations
and cavity resonance but the ceiling
offers a relatively unobstructed pass for the sound and since
low frequencies are non-directional they may generate from anywhere nearby
without affecting directivity or reproduction. Front loaded with a mid-bass horn.
The higher frequencies taken care by a compression driver such as
Altec 288, horn-loaded with a 15 cell CH1505BW multi-cellular, a two
way all horn loaded system.
Ever wonder
where the pipes are pointed in a church organ ?
Has anyone ever seen a flat, square surface acoustic musical instrument ?
Big
speaker Big sound!

Altec Field Coil
Conversions
|
Permanent magnet to field coil electromagnet conversion.
Through many years of listening we agree with many that the field coil
driver is the most natural warm and accurate reproducer in existence,
these drivers use a power supply to feed their field coils to produce
the powerful magnetic field needed for the high efficiency and accurate
reproduction of
music, as it was used many years ago at the begining
of sound amplification, famous drivers such as Altec
284, 287, 801, Western Electric
594, 555 and many
others used
this principle and are the most wanted driver by collectors and
audiophiles as well for their rarity and sound qualities.
