If you’re scratching your head at that headline you’re not the only one. JVC’s new wood cone speaker systems caught our attention with its unique manufacturing process where sheets of birch are soaked in rice wine before being formed into speaker elements.

The company says it pursued wood as a speaker cone material because of its high propagation speed and natural vibration attenuation. However, forming the wood into a speaker cone proved harder than expected with the wood cones cracking and splitting when stamped. An engineer for JVC found the solution dining in Japan – after asking what the restaurant did to make its dried squid so chewy he was told they soaked it in sake. After soaking wood in sake engineers were able to press it into speaker cones without further problems.

The result can be seen in two new speaker systems – the floor-standing SX-WD10 ($1,700) and the SX-WD8 bookshelf system ($1,300). Both are three-driver, two-way bass reflex systems. Each system has a pair of four-inch wood mid/bass drivers with a die cast aluminum frame and a one-inch birch dome tweeter. Frequency ranges from 50Hz to 50kHz in the SX-WD8 and from 45Hz to 50Hz in the SX-WD10. The speaker systems are available now.
