Nostalx
Nostalx is a retro-style Bluetooth speaker that combines music playback with multi-band radio reception. The control system includes two knobs, three buttons and a multi-position switch. The left knob selects radio channels, while the right knob adjusts volume and turns the speaker off at the minimum setting. The multi-position switch moves between Bluetooth, FM, AM and SW modes. The shell can be made of colored plastic, wood or frosted acrylic. Nostalx replaces digital displays with tactile controls to create a sensory listening experience.
