Dominance in Decibels: The Atrend 12SPLDV Dual 12" SPL Enclosure
In the world of high-output car audio, the 12-inch subwoofer is the weapon of choice for a perfect balance of speed and displacement. However, to truly dominate a sound competition or a local car meet, you need an enclosure that can survive the extreme mechanical stress of an SPL-focused system. The Atrend 12SPLDV is that enclosure. Part of the elite Pro Series, the 12SPLDV is oversized, over-built, and precision-tuned to turn raw electrical power into a physical, bone-shaking experience.
Optimized for the "Heavy Hitters" The 12SPLDV is significantly larger than your standard dual 12-inch box. With a total net volume of 3.1 cubic feet (1.55 cubic feet per chamber), it provides the air displacement required for "heavy hitter" subwoofers. These high-excursion drivers feature massive motor structures and long-throw voice coils that need room to move. While a smaller box would choke these drivers, the 12SPLDV allows them to reach their full mechanical limit, providing a smoother, more effortless bass response that carries across long distances.
The Physics of a 33Hz Tune Tuning is the soul of a ported enclosure. A box tuned too high will sound "punchy" but miss the deep lows; a box tuned too low loses efficiency. Atrend has tuned the 12SPLDV to 33Hz—a specific frequency that is widely considered the holy grail for musical SPL systems. At 33Hz, the enclosure provides a massive acoustic gain right where modern bass music needs it most. The rectangular port is engineered to manage high-velocity air movement, virtually eliminating "port chuffing" or whistling, even when your subwoofers are at maximum excursion.
Built to Withstand Internal Warfare When you are pushing thousands of watts into a pair of 12-inch subwoofers, the air pressure inside the box becomes a violent force, literally trying to push the panels apart. Atrend engineers for this reality by using Miter and Dado construction. Rather than just gluing the edges of the 3/4" MDF panels together, they are interlocked. This provides a structural bond that is 80% stronger than standard butt joints. Combined with Atrend’s proprietary "Trick Glue" (rated at 3600 PSI), the 12SPLDV becomes a singular, rigid unit that won't flex, bow, or rattle under pressure.
Industry-Leading Compatibility One of the biggest frustrations for enthusiasts is buying a "high-end" box only to find their subwoofer’s magnet hits the back wall. The 12SPLDV solves this with an industry-leading 18-inch mounting depth. This allows you to install nearly any competition-grade 12-inch driver on the market, from the Sundown Audio SA series to the Kicker Solo-Barics. The 11.13-inch cutout diameter is precision CNC-cut to ensure a snug, airtight fit for a wide variety of brands.
Professional Finish and Connectivity An enclosure this powerful should look the part. The 12SPLDV is wrapped in premium charcoal carpet that is UV-resistant and designed to match most factory trunk liners. The rounded edges provide a sleek, modern look while also protecting the corners of the box from fraying. For electrical connectivity, it features silver spring-loaded terminal cups. These high-conductivity terminals provide a secure, low-resistance path for your amplifier's current, ensuring your subs receive the clean signal they need to perform.
Why the 12SPLDV is the Smart Choice for High-Power Builds:
Maximized SPL Gain: Vented design tuned to 33Hz for maximum low-frequency reinforcement.
Ultra-Deep Design: 18-inch mounting depth accommodates almost any subwoofer magnet.
No-Flex 3/4" MDF: Thick-wall construction prevents energy loss through box resonance.
Professional Longevity: Miter and Dado joints ensure the box won't fall apart over time.
USA Built: Proudly engineered and manufactured with over 30 years of experience.
