Here is a use for Liquidmetal. I wonder if they've thought of this.


RE: Paradigm Loudspeakers:
The Reference Signature S2 v.3 loudspeaker is a good example of what Paradigm can offer for $2598 USD per pair. Flash back to the 2010 Consumer Electronics Show: In my SoundStage! Network article "Mainstream Beryllium," I discussed the use in speakers of that element, which is light but dangerously toxic to work with. Many designers feel that beryllium’s extreme hardness and stiffness make it an ideal metal to make tweeter diaphragms from. A dome tweeter made of beryllium doesn’t "break up," or lose its shape and become nonpistonic, until it’s reproducing frequencies far above the upper limit of human hearing (generally regarded as 20kHz). Because a beryllium dome’s behavior remains linear to somewhere around 40kHz, what you hear up to 20kHz will be more accurate. Whereas beryllium-dome tweeters can be found in much more expensive speakers, Paradigm manages to offer their Signature models with 1" P-BE tweeters at prices that many audiophiles can afford (P-BE = pure beryllium). The P-BE tweeter in the S2 v.3 hands off to the bass/midrange driver at 1.8kHz via a crossover with a third-order slope.
