The product features a remarkable set of specifications that contribute to its outstanding performance. The Xmax, or maximum linear excursion, is an impressive 19mm one-way, which is 70% of the total excursion. This wide Xmax allows the subwoofer to produce powerful, deep bass without distortion.

The design incorporates a vented magnetic gap, which helps to reduce air compression and improve heat dissipation. The optimized high-velocity pole vent further enhances air flow, ensuring efficient cooling and maintaining consistent performance even under heavy use.

An innovative high-velocity vented frame spacer ring has been incorporated, which aids in the overall cooling of the subwoofer. The voice coil former is made of Black Aluminum, measuring 2.5 inches, providing superior heat dissipation for enhanced reliability and longevity.

The voice coil wire is constructed from high-temperature copper, capable of withstanding the elevated temperatures experienced during operation. A large aluminum Faraday ring (Magnet ID) has been included, which helps to improve the subwoofer's efficiency and reduce distortion.

The subwoofer features spring-loaded terminals, ensuring a secure and reliable connection. Moreover, the Stitched-On "XL" Tinsel Leads prevent fatigue and failure, further enhancing the product's durability.

The high-strength cast aluminum frame ensures the structural integrity of the subwoofer, allowing it to withstand the rigors of use without compromising performance.

The subwoofer is optimized for small ported, sealed, and band-pass enclosures, making it a versatile choice for a wide range of applications. The combination of these features results in an optimized coil ventilation system, which contributes to the subwoofer's exceptional performance and reliability.

Regarding the enclosure requirements, the subwoofer is designed to perform best in a sealed enclosure of 0.5 cubic feet or a ported enclosure of 1.0-1.25 cubic feet at 35Hz. The displacement of the enclosure should be 0.10 cubic feet, and the depth should be 6 inches. The outside diameter is 10.5 inches, with a cut-out of 9.25 inches.

Overall, this subwoofer is a meticulously engineered product that delivers outstanding performance, reliability, and versatility. The attention to detail in its design and the incorporation of cutting-edge technologies make it a compelling choice for audiophiles and sound enthusiasts alike.
