The Rockustics Cherry Bomb from SoundTube is a fully weather-proof, direct-burial speaker designed to blend into outdoor landscaping without compromising audio quality. The patented three-way design includes a 5" double-chamber, band-pass subwoofer, a 4" woofer and a 3/4" tweeter all in one compact design. By including the subwoofer in the same cabinet that houses the midrange and tweeter, the Cherry Bomb provides exceptional full range sound without running into the typical phasing issues you have when installing a sub in a different location from the other speakers in a traditional system. This makes installation much faster, easier, and provides cleaner, more accurate sound once installed.
