If you're listening to a stereo outdoors, it goes without saying that the acoustics are going to differ from if you're listening to it indoors. With that in mind, Bose has designed a sound system for Mazda's new 2016 MX-5 Miata, that has both roof-up and roof-down equalization settings.
According to Bose, "clarity and musical detail" can be lost when the roof is down, as they get drowned out by ambient noise. To keep that from happening, the automatically-activated roof-down setting utilizes Bose's AudioPilot 2 technology. Using a small microphone within the car's cabin, it analyzes competing ambient sounds such as wind noise or road noise, then boosts certain frequencies to compensate for them.
The sound system also includes new 2-inch speakers in the headrests, a pair of 6.5-inch speakers in each door, 1-inch neodymium tweeters in each A-pillar, a 5.25-inch woofer housed in a 6-liter enclosure under the front passenger footwell, and a 7-channel digital amplifier mounted below the convertible-top storage space.
