- Designers refine current products and create new ones across the park-
ing lot from the factory, in an R&D lab that used to be a bowling alley.
It houses a sound-killing anechoic chamber so quiet that you can hear

of loudspeakers and measure the performance of other hardware, like
amplifiers. Fiberglass wedges jut out from every surface—even the floor—
to prevent waves from reverberating and muddying the test results.
