SoundQubed prides itself on high quality products that sell for cheaper prices than their competition. The HDC3.118 is no exception to that company policy.
This subwoofer uses a direct-connect system that doesn’t have any terminals at all, which eliminates the lead slap noise often heard in comparable products. The HDC3 uses a multiple spider configuration for improved structural support and the triple joints are hand-glued for maximum penetration in high-stress areas.
The HDC3 has an average power output of 1500 watts and can handle up to a maximum output of 4500 watts. The subwoofer operates at 31 Hz and has a magnet that weighs 340 ounces with a coil 54.229 mm long and 3” in diameter.
