  Coming soon,  single ended  amplifiers
CH Design 230
 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.

CH805BWL in Basswood and Natural Shellac.
 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. more


 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!

Drivers
 

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.
