Gemini GHRK 400 PR Rock Speakers

A pair of "outdoor" speakers designed for discreet integration

The Gemini GHRK 400 PR Rock Speakers stand out with an unusual format: a polymer enclosure with a mineral aesthetic, designed to imitate a rock. The goal is clear: to offer a more elegant outdoor sound solution than a visible speaker, while maintaining sound diffusion suited for a musical atmosphere in the garden. Sold as a pair, they are easy to install to create a homogeneous sound coverage around an outdoor living space.

Intended uses and target audience

These speakers are made for those who want to listen to music outdoors without installing a complex hi-fi system. They are perfectly suited for a terrace, patio, barbecue area, or relaxation zone near water, thanks to their IPX5 resistance (splash-proof) and UV protection. The sound diffusion is primarily for ambiance: playlists, radio, lounge or pop/rock music at reasonable volume, with quick startup via Bluetooth.

Connectivity, battery life, and design: essentials for outdoor use

Bluetooth 5.0: daily streaming freedom

The Bluetooth 5.0 connection allows music to be sent directly from your compatible devices, without audio cables running through the garden. It's an ideal solution for a clean and flexible setup, especially if you move the speakers according to the season or the layout of your outdoor space.

Rechargeable battery: up to 10 hours of listening

Each speaker includes a 2000mAh Lithium-Ion battery rechargeable via 5V micro USB, rated for up to 10 hours of autonomy. The two included micro-USB cables make simultaneous charging of the pair easy, convenient before an evening or day outdoors.

Resonance-absorbing polymer enclosure and UV protection

The resonance-absorbing polymer enclosure is designed to limit unwanted vibrations and improve sound stability, while providing robustness suited for outdoor use. The UV protection complements the design for better resistance against sun exposure.

4'' speaker and stated performance

Each speaker houses a 4'' mid/bass driver, with specifications aimed at ambient listening: frequency response from 100 Hz to 14 kHz and 84 dB sensitivity. The indicated impedance of 4 ohms and the rated power of 300 W position the product as a compact-format outdoor sound solution, designed to fill a space without complicated additional equipment.
