Key Features
The GravaStar Supernova is a portable Bluetooth speaker that delivers high-fidelity sound and sci-fi-inspired design in equal measure. With a 25-watt output powered by a 3-inch full-range driver and 1/2-inch tweeter, this speaker fills any room (or campsite) with bold, balanced audio. The futuristic zinc alloy shell houses fold-out tripod legs for stable placement and includes a carry handle for easy transport.
Product Ref: 330749
The GravaStar Supernova blends high-tech style with real-world durability. Its distinctive mecha-inspired form features a central lantern-style light suspended on foldable tripod legs, giving it both a retro-sci-fi vibe and practical stability. The zinc alloy frame isn’t just for looks, it ensures the speaker is tough enough for daily use at home or outdoors. The foldable legs provide stable placement on uneven surfaces, while the compact size and carry handle make it easy to transport.
At the core of the Supernova is a 3-inch full-range driver paired with a precision ½-inch tweeter, delivering 25 watts of well-balanced sound. From deep, controlled lows to crisp highs, it handles everything from music and podcasts to ambient soundscapes with clarity and punch. It’s built for those who want more than just background noise. Even in outdoor or open settings, the Supernova holds its presence, delivering audio that feels as bold as its design.
Lighting is built into the Supernova in the most eye-catching way. Choose from 8 solid LED colours or activate one of the animated modes. Dynamic mode pulses light in sync with your sound for a reactive visual experience, while Camping mode mimics the soft, warm flicker of a traditional campfire for a relaxed, analog feel.
Thanks to Bluetooth 5.3, pairing your phone or device is fast, stable, and energy-efficient. For an even bigger sound, link two Supernovas in True Wireless Stereo mode and spread them across a space for left and right channel playback. The 20-metre wireless range provides flexibility for speaker placement in any setting.
Prefer a wired connection? The 3.5mm AUX input has you covered. A premium gold-plated cable comes in the box, so you're ready to hook up gear like turntables, MP3 players, or laptops with no extra adapters needed.
The Supernova is powered by a built-in rechargeable battery offering up to 9 hours of continuous use. Actual run time varies depending on volume levels and lighting mode, but there’s more than enough charge to keep the music going for an evening. Recharging is easy with the USB-C port; just plug in and keep listening. At just 2.2 lbs, it’s light enough to carry anywhere. With its blend of battery endurance, robust build, and bold sound, the GravaStar Supernova is more than a speaker—it’s a portable experience designed for the future of music and light.
