The Atlantic Technology Nexa 1 has a physical footprint of 220.98mm wide, 95.25mm tall, and 71.12mm thick, with a total volume of roughly 1497 cm³ and a weight of 1180g. It houses two 66mm drivers and features a control panel directly on the unit, while forgoing a touchscreen, RGB lighting, remote control, and travel bag. The speaker carries an IPX5 ingress protection rating, meaning it can withstand water jets, though it does not use neodymium magnets in its driver configuration. There is no detachable cable, and the unit is not a neckband-style speaker.
The Atlantic Technology Nexa 1 delivers a combined audio output of 2 x 30W and covers a frequency range spanning from 20Hz to 20,000Hz. It includes a passive radiator to support low-end reproduction, though it does not feature a dedicated subwoofer or magnetic shielding. The speaker operates as a mono unit, as stereo speakers are not part of its configuration.
The Atlantic Technology Nexa 1 is equipped with a built-in rechargeable battery that is not removable, offering a battery life of 15 hours per charge. Recharging takes approximately 3.5 hours, and the speaker does not support wireless charging. There is no battery level indicator included to display the remaining charge status.
The Atlantic Technology Nexa 1 connects wirelessly via Bluetooth 5.3 with a maximum range of 100 meters, and also offers an AUX input for wired audio playback. It includes a single USB Type-C port and an external memory slot, expanding its input options beyond wireless streaming. NFC pairing, Wi-Fi, Ethernet, AirPlay, Chromecast, Auracast, and Bluetooth LE Audio are not supported, and the unit lacks a 3.5mm audio jack socket, a 3.5mm male connector, and a microphone input. On the codec side, none of the advanced Bluetooth audio codecs are present, including aptX, aptX HD, aptX Adaptive, aptX Lossless, aptX Low Latency, LDAC, and AAC, and the speaker is not DLNA-certified.
The Atlantic Technology Nexa 1 can be used wirelessly and supports remote smartphone control, allowing playback management from a connected device. It provides voice prompts for audio feedback during use and includes a sleep timer for scheduled shutoff. The speaker does not offer fast pairing, voice commands, a mute function, built-in radio, or the ability to function as a power bank for charging other devices.
The Atlantic Technology Nexa 1 does not support stereo pairing, meaning it cannot be paired with a second unit to create a two-channel stereo setup.
