Gravastar Mars Pro Bluetooth Speaker

Product Overview

The Gravastar Mars Pro is a Bluetooth speaker designed to deliver deep bass, accurate mid-range, crisp highs, and an equal-loudness contour. Its technology produces high clarity and punchy bass even at low volumes, allowing users to "hear everything and feel it." The speaker features a two-way system with a passive bass radiator for a big sound in a small enclosure. Using DSP 4-way digital crossover, it independently compensates and tunes the low bass, mid bass, mid, and high frequencies to ensure clear sound separation, balanced tonality, and accurate sound reproduction.
