Original Product Details and Specifications

If you want a 12" subwoofer that is built for serious low-frequency output without giving up efficiency, the SoundQubed HDX4 12 is made for that kind of system. This dual voice coil competition subwoofer was designed to play lower, stay efficient, and deliver stronger performance in the frequency range many real-world vehicles and modern music demand. It is a strong choice when you want deep bass, hard output, and a subwoofer that can make the most of your amplifier power and electrical system.

The HDX4 line builds on the HDC platform with improved low-frequency performance, increased excursion, and stronger overall durability. The cast basket allows for larger diameter spiders, giving the suspension more room for cone and spider travel while also improving airflow and heat dissipation. It also uses spiders with more and higher rolls to increase freedom of movement and lower Fs, along with a higher surround profile to reduce material stress while increasing excursion.

Strength matters just as much as output, and the HDX4 12 is built with that in mind. It uses a fiberglass-reinforced pulp cone for added rigidity, a non-press cone formation process to increase cone wall cross-section without unnecessary mass, and high-quality American-made voice coil wire and adhesives to increase the thermal working range of the coil. Thicker black-anodized aluminum formers are also used to improve thermal transfer from the coil wire.

If you are shopping for a 12" competition subwoofer, SoundQubed 12" sub, HDX4 12, low-frequency SPL subwoofer, or high-excursion dual voice coil subwoofer, this model checks the right boxes. The HDX4 12 is rated at 2000 watts RMS and 6000 watts peak power, uses a 4" voice coil, a 403 oz motor, 21 mm Xmax, and is available in D1 and D2 options. The recommended ported enclosure range is 1.75 to 2.75 cubic feet, giving you room to build around strong output and deep low-end response.
