Advanced materials

The SWS-15D2 can handle up to 500 watts of RMS power, so you can drive it hard and it'll keep up. The tough 15" Kevlar® treated cone stays rigid under pressure, while its rubber HAMRS surround allows for maximum excursion. Its dual 2-ohm voice coils allow for wiring flexibility which helps if you plan on adding another subwoofer down the line. Also, it rocks in both sealed and ported boxes, so you can choose an enclosure that suits your tastes.

Note: If you are wiring this DVC sub for lower impedance, make sure that your amp is compatible.

To drive this single subwoofer, we recommend a mono amplifier rated between 375 and 750 watts RMS at 4 ohms. For more information, please refer to our article on How to Match Subwoofers and Amplifiers.

Disappointment.

Seth from Greenville, SC on 8/19/2017

Me and my buddy did the bogo deal on these and both speakers failed within a week. He had his hooked up to an old school fosgate amp and I had mine on an alpine pdx-600.1 with the gain set to minimum and at 4ohm. Will never buy another alpine sws sub. Can't believe alpine put their name on this turd.

Pros: Had decent sound for a day.

Cons: Voice coils are junk.

Crutchfield Customer Review (What's this?)

This is a great sub. The new type S is the same build as the old type R. Unfortunately I have this in a sealed box. Still sounds great but would love to hear it in a ported box.

Pros: Good quality, attractive finish.

Cons: It isn't buy one get one free.

Features

Kevlar Reinforced Pulp Cone: This Alpine Type-S subwoofer uses a parabolic cone structure, with a Kevlar reinforced pulp cone and a Poly-Mica dust cap. Kevlar adds strength and tear resistance to the woofer cone while maintaining the benefits of a pulp cone design. The oversized, inverted poly-mica dust cap increases rigidity and virtually eliminates cone distortion at extreme volume levels.

HAMRS: The woofer features a High Amplitude Multi Roll Surround (HAMRS), made of Santoprene, that allows a large linear excursion and greater SPL. The HAMRS design allows extreme excursions without sacrificing valuable cone area.

Progressive Spider: The progressive Conex spider has reinforced layer tinsel leads to ensure reliable and consistent control of the tinsel leads and eliminate any mechanical noise or interference often seen in high excursion cone designs.

Compound Radius Curve Pole Geometry: Alpine's Patented Compound Radius Curve pole geometry ensures a symmetrical magnetic field, while optimizing flux density to reduce distortion and further improve power handling and output.

Oversized Voice Coil: The oversized (65mm), high-temperature, 5-layer dual voice coils offer power handling up to 500W RMS / 1500W Peak (250 watts RMS per coil).

Dual Voice Coils: For system flexibility, the woofer has two 2-ohm voice coils. When the voice coils are wired in parallel, the woofer presents a 1-ohm load. When the voice coils are wired in series, the woofer presents a 4-ohm load.

Spring Terminals: The spring post terminals are all located on one side of the woofer. The terminals will accept pin connectors, single banana plugs, or bare wire up to 8 gauge.

Jumpers: Included with the woofer are two voice coil terminal jumpers. These jumpers allow you to easily wire the voice coils in parallel (for a 1-ohm load) or series (for a 4-ohm load).

Enclosure Compatibility

Sealed Box: Alpine recommends a sealed enclosure with an internal volume between 1.32 and 2.07 cubic feet, with an ideal volume of 1.34 cubic feet. Sealed enclosures provide the most control over a woofer, will handle a lot of power, and provide accurate sonic reproduction, making them suitable to all types of music.

Ported Box Volume: The recommended ported box volume ranges from 2.07 to 3.07 cubic feet, with the ideal size being 2.67 cubic feet, using a slot port measuring 16" (W) x 1.25" (H) x 21" (L).
