One of the standout features of the SML-10-D4 is its Xmax, which measures 11mm one-way by 70%. This allows for extended excursion, resulting in greater bass output and a more powerful low-end response. The Xmech, or mechanical limit, is a hard limit of 25mm one-way for 12-inch subwoofers and 20mm one-way for 10-inch subwoofers, ensuring the subwoofer's longevity and reliable performance.

The subwoofer's RMS power rating of 500 watts speaks to its impressive power handling capabilities, making it suitable for a wide range of audio applications. The use of a Black Aluminum 2.5-inch voice coil former contributes to superior heat dissipation, allowing the subwoofer to handle high-power inputs without compromising its performance.

Another notable feature is the High Temperature 4-Layer copper voice coil wire, which enhances the subwoofer's durability and thermal management. The Stitched-On "Mini-XL" Tinsel Leads further reinforce the subwoofer's construction, preventing fatigue and failure over extended use.

The Vented Pole-Piece and Multi-Vented Magnetic Gap design of the SML-10-D4 optimizes airflow and cooling, improving the subwoofer's efficiency and reducing the risk of thermal issues. The Dual-Magnet Design ensures an appropriate motor force factor, contributing to the subwoofer's mid-range performance.

The custom-tooled cone shape of the SML-10-D4 is designed to reduce mechanical noise during high-excursion operation, enhancing the overall audio experience. The Bolt-through motor design further strengthens the subwoofer's build quality, ensuring maximum longevity and resistance against mechanical failures.

In terms of specifications, the SML-10-D4 boasts an RE (Ohms) of 6.850, an FS (Hz) of 36.116, a VAS (L) of 24.828, a Qes of 0.469, a Qms of 2.766, a Qts of 0.401, a BL (NA) of 21.022, an Mms (Grams) of 133.242, a Cms (uM/N) of 145.749, and a Sens (dB @ 1w/1m) of 85.8dB.

The recommended enclosure sizes for this subwoofer are 0.5-0.75 ft^3 for a sealed enclosure and 1.0-1.25 ft^3 for a ported enclosure. The recommended tuning frequency is 35Hz, and the recommended port area mounting depth is 3.78 inches.
