Alpine SWS-15D4 15 Subwoofer (4Ω+4Ω) (SWS-15D4)

( Item in stock! )They’re so good, we had to redesign the Type-R

The new fourth-generation Type-S subwoofers have undergone a revolutionary redesign, leaning heavily on patented technologies developed for the Type-R series. The result is a subwoofer that is so good we had to redesign the Type-R. These new subwoofers redefine the expectations in their class. Altogether, they offer significantly improved output, deeper bass extension, more control and even greater power handling.

Master of All Trades, Jack of None.

Taking a clean-slate approach in the development allowed Alpine engineers to design the subwoofer to excel in nearly every category. Whether in a small sealed or vented enclosure, these new subs possess the ability to be articulate and defined or powerful and authoritative. Deeper and more refined looking than their predecessors, they now sit at 5.6” (SWS-10D4 & SWS-10D2) and 5.9” (SWS-12D4 & SWS-12D2) deep, making them flexible for many different installation options.

Genetically Built Like Type-R

More Excursion = More Output

The new FEA-Optimized Motor Structure together with our revolutionary HAMR Suspension Design gives the new Type-S Subwoofers the highest X-max and SPL output in the category.

With a real-world, measured 15mm of one-way X-max, the new Type-S Subwoofers deliver best-in-class output, ultra-low distortion, and unparalleled sound quality. Borrowing the HAMR suspension from the Type-R, these new Type-S subwoofers have over 30mm of one-way stroke, for a total of nearly 3” of peak-to-peak excursion!

Underhung Design = More Control

The new dual-sided CRC motor structure mimics that of the Type-R Thin subwoofers, providing these subs with an ultra-linear, highly controlled sound. This patented design (US Patent # 6,639,993) creates a perfectly symmetrical and linear magnetic field for the coil to travel in, minimizing distortion while enhancing sound quality. The high-grade double-stacked magnets ensure adequate clearance for high excursion while providing the energy needed to power these beasts.

Keep it Cool = Keep it Playing

Alpine’s Patented Airflow Management System (US Patent #7,684,585) helps minimize power compression and ensures reliable long playing time by actively wicking output-robbing heat away from the Voice Coil.

The massive 65mm (2.6”) diameter voice coil provides nearly double the surface area when compared to the previous 38mm (1.5”) voice coil. Similar to having a larger intercooler in a race car, the larger surface area allows for the voice coil to cool faster, ensuring that your bass tracks cleanly and reliably, without compression.

Massive Voice Coils = Maximum Durability

The new 6-layer (Dual 4Ω) and 5-Layer (Dual 2Ω) coils are wound on a spiral-cut aluminum former. The massive coil, along with the black anodized coating, provides these woofers the thermal mass and cooling capacity to achieve a full 500W of RMS power handling. Peak power… try 1500W.
