More about the product
The Hertz SS12D2 SPL Show 12-Inch Subwoofer is engineered for extreme bass performance in high-output car audio systems. Designed for enthusiasts who want deep, powerful low frequencies, this subwoofer combines advanced materials with rugged construction to deliver consistent performance under demanding conditions.
The SS12D2 features a cone made from non-pressed paper reinforced with cotton fibre. This combination provides excellent rigidity while keeping weight low, ensuring fast response and accurate bass reproduction. The high-roll surround allows for maximum excursion, enabling the subwoofer to move large volumes of air for impactful low-end output. This design is ideal for SPL applications where both strength and flexibility are essential.
The dual 2-ohm voice coil configuration offers wiring flexibility for different system setups and amplifier matching. This makes it suitable for single or multi-subwoofer installations in high-power systems. The heavy-duty motor structure and reinforced components ensure durability and reliability even during extended high-volume sessions.
Cooling is a key feature of the SS12D2. It incorporates an advanced ventilation system to maintain optimal voice coil temperature, reducing the risk of thermal failure during intense use. This makes it a dependable choice for both daily driving and competitive SPL environments.
The SS12D2 is optimised for vented enclosures, where it can deliver maximum output and efficiency. It is capable of handling very high power levels, making it perfect for pairing with dedicated mono amplifiers from the Hertz SPL Show range.
While this subwoofer excels at producing extreme bass, it is designed exclusively for low-frequency reproduction and does not cover midrange or high frequencies. For a complete system, pairing it with amplifiers and speakers for mids and highs is recommended.
The Hertz SS12D2 SPL Show subwoofer is a top choice for those who want to feel the bass as much as hear it. Its combination of advanced materials, high excursion capability, and cooling technology ensures reliable performance in high-power installations.
