GravaStar Bluetooth Speaker Mars Pro

Step away from generic boxy audio hardware with the unmistakable presence of the GravaStar Mars Pro. Engineered to resemble an armored extraterrestrial robotic probe, the speaker is built around a heavy-duty die-cast zinc alloy spherical shell. Weighing a grounded 1.3 kg, the structure is supported by three articulated folding tripod legs equipped with shock-absorbing rubberized pads. This elevation decouples the speaker from your desk surface, virtually eliminating vibrational interference and acoustic resonance when pushing low-end frequencies.

Acoustically, the Mars Pro is engineered for bold clarity and visceral low-end response. At its heart is a 20W dual-speaker sound system comprising a custom-engineered 2.5-inch full-range driver alongside a dedicated 1-inch high-frequency tweeter. A specialized passive bass radiator at the rear moves in tandem with the internal drivers, allowing the compact sphere to generate heavy, authoritative sub-bass without muddiness. Proprietary DSP audio algorithms utilize an equal-loudness contour to maintain tonal balance across the full frequency spectrum, ensuring full bass texture and crisp trebles even at low listening volumes.

Interactivity is tactile and intuitive. Running down the top crest of the speaker is a capacitive touch-sensitive volume bar, allowing you to adjust volume levels with a simple finger swipe. Built-in multi-zone dynamic RGB lighting accents the speaker core and chassis contours, offering six distinct lighting modes including solid tones, pulsing gradients, and music-sync rhythm tracking.

Wireless transmission is powered by Bluetooth 5.0 with low latency and support for True Wireless Stereo (TWS) pairing, enabling you to link two Mars Pro units together for an expanded, discrete left/right stereo soundstage. Powered by an internal rechargeable lithium-ion battery, the Mars Pro delivers up to 15 hours of continuous playback on a single charge and supports USB Type-C fast charging as well as GravaStar’s optional magnetic wireless charging base.
