Just recently purchased the ff: speakers
1. Aurex SS-F07 (sorry no pictures yet)
- Doesn't have any review in the internet (not that I am aware of)
- To me it has excellent vocals
- Good imaging
- Low and high frequency reproduction is very good
2. Sony SS-A5 (La Voce)

Here is what he says of the tweeter
"Around the tweeter as for the baffle it is part, but it has become 2 piles. It is the semi hard type
diaphragm which uses the bio cellulose which 3 corporations of the SONY & Ajinomoto Co., Inc. & Agency
of Industrial Science and Technology Research Institute for Polymers & Textiles developed jointly. It is not
to press to process to dome type, you asked that from beginning it grows the fiber in the mold of dome
type. The bio cellulose is the cellulose which the bacterium which is called the acetobacter creates. The
bio cellulose is used for also the portion of the single unit sale unit of FOSTEX, but it is unclear from
equality with those which SONY uses. With SONY this bio cellulose is used as a diaphragm of the
headphone. Also patent is taken.
Separated method of bio cellulose
Bio-polymer research: Patent 2766182
Production method of the bacterium cellulose which uses PQQ non formation stocks
Bio polymer research: Patent 2767551
The bio cellulose (the bacterium cellulose) purity to be higher than the cellulose which the plant makes,
because minute structure (1/100) it is extraordinary the cellulose fiber of the plant, for example various
merits (, because young's modulus has about the same as the aluminum), as a new material it is the
material which is expected. Culture it can do to be done, with such as coconut fruit juice to remove the
cellulose in several days so is. The azotobacter melts permeating the protein disassembly enzyme, so is.
The bio cellulose was expected as a disassembly characteristic plastic, but price becomes the problem and
has not spread."
