The JBL Authentics 300 in Black is a portable smart home speaker that blends a retro aesthetic with modern audio technology. Its design features a black leather-like enclosure and a Quadrex grille, complemented by a cast-aluminum handle that makes it easier to move the 4.9 kg device around your living space. Inside, a 2.0 stereo system delivers 100W of power through a 5.25" woofer, a 25 mm tweeter, and a 6.5" passive radiator, covering a frequency range from 45 Hz to 20,000 Hz for a balanced sound profile. You can connect your devices via Bluetooth 5.3 or Wi-Fi, with built-in support for Chromecast, AirPlay, Spotify Connect, and Alexa Multi-Room Music. For those who prefer wired connections, it includes a 3.5 mm mini Jack and USB Type-C ports. The speaker allows you to use Google Assistant and Amazon Alexa simultaneously, while the JBL One app provides further control over your listening experience. Physical buttons on the chassis let you quickly adjust volume, bass, and treble without needing your phone. Designed for versatility, this speaker includes a 4800 mAh rechargeable battery providing up to 8 hours of cordless playback, though it can also stay plugged into any 100–240 V outlet. Measuring 34.2 cm in width, 19.6 cm in height, and 18 cm in depth, its combination of black plastic, metal, and artificial leather makes it a substantial piece of equipment that fits well in both modern and classic interiors.
