There are bending wave planar speakers
("violin principle" if you like)
which reproduce brass seamlessly as well as
there are good wave guided conventional speakers
reproducing strings very well.

But a (electrodynamically excited) violin can neither
properly reproduce a recording of itself nor can it closely
reproduce a recording of a different violin ... that is for sure.

A system "emulating" a different system always needs
more resources than the system to be emulated.

A system with a small set of "eigenfrequencies" and
little overlap between those eigenfrequencies cannot
reproduce a system with a large set of eigenfrequencies
and broad overlap.

But if you want to reproduce an instrument with a different
instrument, you can excite e.g. a contrabass with the
violin signal. Since the contrabass will have more closely
spaced eigenfrequencies in the violins range than the violin
itself, it will be able to reproduce even different violins
reasonably well.

Slightly damping the contrabass' corpus will also contribute
to neutrality.

The so modified contrabass corpus will even reproduce
a trumpet after some tweaking.

But how to reproduce a contrabass itself or a Bösendorfer ?

That is the point where you need an instrument, having
lower eigenfrequencies and a much more dense distribution
of those, than all instruments to be reproduced on that
"meta instrument".

Yes!

Just go for it and Damn the Torpedoes!

Our products are string speakers using resonance of body of string instruments that attached acoustic vibrators to express strings’ original sounds. They play two roles as speakers and musical instruments. A wonderful sound can be embodied through the acoustic vibrators even if a performer doesn’t play the musical instrument. Actually, musical performance is also possible. In addition, we resolved existing problems of speaker systems concerning acoustical and spatial design. Plane wave emanating from the string speakers clear acoustical blinds in spaces. Further, these string speakers go well with the interior of the spaces.

2 more and they will be growing speaker flowers but no one will want them...
because nanobite speakers will be cheaper and faster.

Strange thing, that a manufacturer does not

Hi LineaArray.
"The propagation of bending waves........."
"The fibers should be orientated....."

1 - Exactly how did you come to these conclusions?
2 - You've done specific experimentation, testing, data that supports your statements?
3 - How many cone types and designs do you make?

Thanks

Mark.

We can all be all knowing in our own bedrooms. I still like the nanobots idea. I cant understand why polly Kevlar and those composites never where as good as most thought they should of been. Where back to organic things again. Cellulose has promise. I think nxt drivers seem like good way of playing around with weird speaker materials. Why they spent so much time investing in wood cones can only be a fashion. Flat panels are the future or spheres. I am so over this thread. Dont insult me I wont be around to read. I have horns (real speakers) to talk about. Come into my horn threads if you want to finish insulting me. Good luck

Just curious- Has anybody heard these wooden cone speakers (beside the mentioned?) I had a chance to sell the JVC mini stereo system with the small wood cone speakers, a 3"-4" fullrange all in a tiny desktop higher end system- 2.0. Personally, I thought they were excellent and sold quite a few of them to mainly people with offices and women, weren't bass heavy but clear midrange and highs were very good almost shrilly and a very good speaker IMO. I'm in the search for a 8" fullrange, if there was a wooden cone one- I wouldn't mind giving it a try.

The fashion trend in speaker design is to leave the drivers exposed. Metal and paper do not stand up well to probing fingers of curious people. Therefore I predict that wood, Kevlar, carbon fiber and plastics will continue and grow in popularity, at least for the mass market stuff.

Examples of exposed drivers would be the A2 and A5 of AudioEngine or the KRK's. Neither of which to the best of my knowledge even offer an optional face cover.

Short Story: I went to a local mid-fi / Hi-Fi dealer in search of used drivers. The dealer selling Klipsch speakers had five of the aluminum cone type drivers to offer me and an aluminum Monitor Audio driver too. They were in perfect working condition, just with cosmetic flaws, suffering from dings and such from use as demos or in owners homes.
