THE FUTURE IS WITH ATHANAS ACOUSTIC DEVICES

Most of the loudspeaker world operates from two or three perspectives: home, car, industrial. And for good reason: that's where most of the money is. Creative problem solving often means using a device from outside of your industry perspective catalog. We take a different approach… think about what you want sound to do, and tell us about it. Maybe it can be done. We'll let you know.

We currently have several patented designs of timely interest. The FEAT transducer has a frequency response in excess of 50kHz, making it compatible with the new SACD high density recordings. It has no moving parts other than the diaphragm itself, and no magnets to interfere with video or other electronics.

Also, we can make woofers work with ferrofluid, without a traditional spider suspension. Using a proprietary high performance magnetic fluid, our patented LMS system increases power handling, dynamics and fidelity, while reducing resonances and parts count. Truly more for less. Applications include harsh environments as well as high end audio.

We have developed but not yet released an innovative flat panel loudspeaker that can be sectioned to play more than one channel on one panel, and is as clear as window glass! More details shortly when legally allowed. All inquiries on company letterhead, please.

Our work continues on wide range real time sound cancellation. We are looking for interested parties who would like to join us.

As always, we would like to help develop your loudspeaker project. Whatever the price point, from desktop to commercial installation, we can squeeze maximum performance from your requirements.

Athanas Acoustic Devices

has been awarded patents for two proprietary transducer technologies, available for development and inclusion in your loudspeaker products. We are also supplying finished metal cone drive units with magnetic suspension.

Do you need a superior audio product? We can create a speaker product for you, from desktop audio up to high-end and home theater units. We also do product assessment and acoustic tuning of current products. This includes the small physical and electrical changes that add up to big performance differences that can make or break a product in the marketplace.

    
 
 
    

Ferro-Electric Acoustic Transduce

FEAT Patent

This is an elegantly engineered ultra-fidelity transducer where the motor and the diaphragm are one and the same. A thin, lightweight piezo-electric plastic film expands and contracts in one direction only when an audio signal voltage is applied to it. Electrostatic quality sound is produced in line sources of any length desired, and line sources may be ganged together to form rectangular sound sources with as little depth as ½ inch.

High frequency response may extend to as high as 50 kHz. Low frequency response is dependent on surface area and output level desired. In typical home applications, 5 sq. inches will yield a cut-off of 2 kHz @ 87 dB, 1w/1meter. 45 sq. inches will extend the cut-off down to 450 Hz.
Applications include flat panel/picture frame loudspeakers, High-end tweeters, and automotive use. This speaker requires a mild step up transformer for operation. Note that it can operate directly from a high voltage amplifier, such as directly from tube circuits without a step-up transformer: very rugged and durable.

Liquid Magnetic Suspension

LMS Patent

This is the only technology available that successfully uses ferrofluid in bass drivers. This is the basis for the famous NEAR drivers. The benefits are numerous:

    
   
    
))Increased power handling due to cooling of the voice coil: up to four times steady state, ten times on impulse response.

))Increased dynamic performance, on two fronts. The cooling of the voice coil greatly reduces thermal compression caused by the increased resistance of the voice coil under power. The free and linear resistance of the movement of the cone due to the elimination of the non-linear spider also enhances the output at high excursions.		 )) Damping of unwanted resonances. The constant oil bath of the voice coil damps parasitic resonances in voice coil formers and high Q diaphragm materials such as metals and ceramics, improving frequency response and sound quality.

))Improved clarity. The elimination of the distortion prone spider directly behind the speaker cone eliminates a secondary, low quality sound producer, the spider itself. Spider distortion can be heard right through the cone itself.
