Step Up Your Bass Game — SoundQubed HDB2-212LE-D4 Dual 12" Loaded Ported Enclosure

When dual 10s aren't enough, the SoundQubed HDB2-212LE-D4 steps in. This factory-matched dual 12" loaded and ported subwoofer enclosure delivers 900W RMS and 1800W peak — earth-shaking low-end performance in a plug-and-play package.
