TWARON Angel Hair

A innovative damping material, working different from all excisiting materials like foam, BAF enz.


Improves sound quality of about all excisiting loudspeaker systems. 
Just remove all loose material and replace it with this Angel Hair by trial and error.

TWARON Angel Hair is a sound damping wadding product
It was Leo Busscher of Dutch Arnhem plant of Teijin who first experimented with way more basic material in his high-end loudspeakers, and so igniting a string of events with this very interesting material as a result. It is further developed for optimal absorbing and damping of the audio frequency range, f.e. in loudspeakers, damping panels, etc. It is easy to work with, not aging and stays in place since it has the permanent attitude of expanding, so it will fill the space it is given. Behaviour of this material is so different compared to all known other materials that you simply have to try this at least. The extreme thin synthetic TWARON fibers are cut in 60mm pieces and carded to the elastic and easy  to use wadding mass as it is supplied. Unlike glass- and other fibers used today, TWARON is conducting heat (due to caused vibrations) very well and so absorbing the acoustic movement energy extremely well and in a very different way compared to all other known materials used for this purpose. Together with the choice of the correct length of the fibers and the right way to card it to a workable mass, the results are quite ashtonishing as noticed now by an increasing number of professionals in the audio community. Compared to kg price of other materials it is expensive, but please note that you need only around 10-20% of the weight of other materials. Besides that and even more important: sound WILL IMPROVE dramatically, especially noticed in small signal response. Compared to prices of better wiring,equipment, absorbers, etc. it is even cheap regarding improvent of sound. Besides damping loudspeakers in an efficient and quality increasing way, filling absorbtion panels or sound traps with even more TWARON Angel Hair, will cause an absorbtion of a certain mid/high range of room reflections as shown in the graphs below. A filling of >20 grams/liter will cause a 100% damping of a certain high frequency range while leaving the stuffed panel on the other side. The more you fill, the less low frequencies will be damped due to the fact that the TWARON Angel Hair filling becomes more dense and so restricted in moving. A maximum is achieved with 150 grams/liter where the material gets so dense that it shows a steep absorbtion characteristic, where voice/instrumental range and harmonics are damped at maximum and bass is left unaffected. This could be an ideal solution for sound improvement of very "empty" or "small" sounding rooms (f.e. small stages) where voices and fine instruments need to be reproduced.
