SoundQubed HDB2-210LE-D4 Dual 10" Loaded Ported Subwoofer Enclosure 800W RMS

Plug-and-Play Bass That Hits Hard — SoundQubed HDB2-210LE-D4 Dual 10" Loaded Ported Enclosure

Skip the guesswork of matching a box to a subwoofer. The SoundQubed HDB2-210LE-D4 is a factory-matched, loaded and ported dual 10" subwoofer enclosure that delivers 800W RMS and 1600W peak power right out of the box. Two 4-ohm dual voice coil subwoofers wired in parallel to a 1-ohm final load give you maximum power transfer from your amplifier, while the 35Hz port tuning keeps the bass tight, deep, and controlled. Whether you're building a daily driver or an SPL setup, this loaded enclosure gives you serious bass in a mid-sized footprint without the hassle of a custom build.
