Earthquake Is Hiding Something Under that Rock

Coaxial driver arrays lay beneath the Granite-52 outdoor rock speakers from Earthquake Sound. They go for $450/pair plus another $799 for the Granite-10D subwoofer. A spokesperson said reliability in the tough outdoor environment is one reason to go with Earthquake. The company also showed the SWAT 2.4 wireless transmitter/receiver combo, $349/pair, which can be powered by USB or wall wart. Maybe just the thing to make the leap from your main rack to the sub or surrounds when conventional speaker cabling is inconvenient.
