CGN specializes in sound system design. We have a particular focus on the pro audio industry but we have also produced a number of products for our CE customers. Over the years we have with worked with several large companies to develop the right OEM speakers for their product line. We can source or tool a variety of loudspeaker parts. Contact us if you need custom enclosures, x-overs, woofers, tweeters, compression drivers, horns and Neo Ribbon drivers. We listen to your needs and provide sound technology that's state of the art.
One of our trademark speaker components is pictured in slhouette form on the right, the B-Hive motor. Form follows function with this proprietary invention. This is a radical approach to speaker design that uses a neodymium ring magnet that is encased in a low carbon steel pot structure. The key advantage of this design is high excursion. Some of the other benefits of this approach include high efficiency, low distortion, and high output bass with extended frequency response.

We also market the Lorentz Audio speaker brand. This name is a tribute to the man that put forth the fundamental laws of Physics under which all dynamic loudspeakers operate.
Lorentz's Law, yields that the force on a moving charge due to a magnetic field:
q Columbs, V meters/second, B Amperes/meter, theta is the angle between V and B
F is directed according to the right hand rule.
This essentially means that when positive current is connected to the voice coil wire in the magnetic gap the resulting force moves the cone outward. Reverse the polarity and the force now acts to pull the cone inward towards the speaker basket.
It is in this spirit of this science that we are proud to offer the Lorentz Audio line. Some of our most popular models are the Push Pull Neo Ribbon Drivers 5" & 8" models. Check out thier specifications at http://www.ribbonloudspeakers.com

We also offer a line of custom modular column full range loudspeakers available in a wide variety of finishes and mounting hardware. The newest is an all NEO6.5" Version of the CGN6685 Line array contains 6 x 6.5" woofers and 5 x 8" ribbons.(Picture pg.3) The total weight of the neo line array is only 26 Lbs!(11.8 Kgs.) That's a weight savings of 12 Lbs.( 5.5 Kgs.) 32% per cabinet over the ceramic magnet version. The Neo 6.5" woofers use high temperature Neodymium magnets that are extremely powerful and ultra lightweight. These woofers are MADE in the USA. When all of these Neo CGN6685 speakers are stacked up the weight savings quickly adds up. Some additional benefits include video shielding so they can be used around computers, CRT monitors and magnetically sensitive recording media. No stray magnetic flux means that these speakers are more cost effective to use and transport. The NE06.5"6685 Line Array Meter Module is more efficient and puts out more SPL/mass!
