NXT doesn’t make products directly. They license the technology and help other companies bring their products to market. One of the companies using NXT’s flat speaker technology is Shinhint. They demonstrated several products, including monitors, TV sound bar speakers, and tabletop speaker phones as part of NXT’s press presentation this morning.
While these aren’t the smallest drivers on the planet, the three NXT-based Shinhint drivers in the picture are pretty darn small (the pen shown here is actual size) (so is the hand, by the way), and they sound impressively big.
