Q Power is built for bass enthusiasts who demand more — more power, more precision, and more durability. The Q Power HD212VL Dual 12-Inch Vented Subwoofer Box is an extra-large, heavy-duty enclosure engineered for hard-hitting sound and long-lasting performance.

Designed with two separate chambers and a shared center slot port, this enclosure delivers strong, consistent airflow and deeper low-end response. Each chamber offers 2.25 cubic feet of air space, perfectly tuned to 42 Hz for accurate, punchy bass that maintains control even at high volume. The enclosure features a 1-inch MDF front face and 3/4-inch MDF side panels, combining rigidity with acoustic balance to eliminate unwanted flex or resonance. Inside, precision internal bracing supports clean, distortion-free output, built for subs that demand power and stability.

Gold-tipped spring-loaded terminals ensure secure, corrosion-resistant connections for maximum efficiency. The premium charcoal carpet wrap protects the enclosure from wear while giving it a clean, professional look that fits seamlessly into any setup.

Whether you’re building a show system or upgrading your daily driver, the Q Power Dual 12-Inch Vented Subwoofer Box gives you the perfect combination of size, strength, and sound. Engineered for impact. Tuned for clarity. Built the Q Power way.

Freight Shipping Information (LTL)

Some items are too large to be shipped with a regional carrier, FedEx, or USPS, and we ship these items with our freight carriers.

Please read the information below so you fully understand the delivery process and requirements.

Required Actions

We will need your phone number for the delivery. The carrier will need to call you in order to set up a delivery time. Please make sure the number you provide during checkout is the best one to reach you. If paying with PayPal, please make sure the number on your account is accurate.

You'll need to inspect your package upon arrival before you sign. If your order arrives damaged, you should sign "DAMAGED" on the delivery receipt. If the item is damaged to the point that it is not usable, you can refuse the item.

Please notify and, if possible, send photos of any damage to vminnovations_help@email.spreetail.com, along with your order number. A member of our Customer Experience team will reach out to you with further instructions.
