Chela Audio
(CH Audio Design) |
|
Chela Audio is dedicated to hand crafted works of art, we are not mass
produced audio
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 One job at a time!

Amplifiers
I will build your dream amplifier, single ended or push-pull, with your favorite tube to your specs.
A photorendering of your design will be provided before any job is started.
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. |
Pre-amplifiers Coming soon

Multicellular
horns
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.
The honky horn characteristic is not present in my wood designs, only true natural and sweet sound.

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 parallel reflections. Fired up to the ceiling through
a
straight passage of a calculated shape, a mixture of straight horn, and
tuned
pipe that could be used anywhere in your room or in the
corners using the ceiling and adjacent walls as an extension
of the horn.
The floor is often cramped with objects causing unwanted vibrations
and cavity resonances but the ceilings
offer 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 reproduced 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 square, flat surfaced acoustic musical instrument ?
Big
speaker Big sound! |

Altec Field Coil
Conversions
|
Permanent magnet conversion
to field coil electromagnet
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 beginning
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 drivers by collectors and
audiophiles as well for their rarity and sound qualities.

CH 806Hy Hybrid Driver
Introducing the CH806Hy hybrid drivers,
an Alnico magnet and a powerful coil all in one unit, a hybrid
type of
driver with both permanent magnet and field
coil, compromising between the convenience of a permanent
magnet and the great sound of a field coil driver.. |

CH416AFC
Field Coil
Woofer
|
CH416AFC Field Coil Low Frequency Driver
With
a variable power supply the parameters can be changed by adjusting
the potential to the field coil from almost no magnetic
flux to over 16000 Gauss and a fine tune of your cabinet to the
driver is possible, or change it to your preferences and taste.
A huge 8 Lbs field Coil.

CHFC1 Field Coil
High Frequency Driver |
CHFC1 Field Coil High Frequency Driver
The
CHFC1 driver incorporates a huge field coil that
requires 28V dc at 0.67 amp.
The huge size of the field coil provides the driver with a very powerful magnetic fiel
with negligible heat generation. |
