Find products that fit. Get a rush of clean, loud bass from a Type-S subwoofer, and you'll understand why so many car enthusiasts bask in Alpine sound. Housed in a heavy-gauge stamped steel frame, the SWSD 12" sub brings out those forceful lows that your existing system can't produce.
The brushed aluminum finish on the cone matches the look of other Type-S speakers. You'll enjoy distortion-free sound, thanks to a perimeter venting system that forces hot air away from the voice coil.
The tinsel leads are built directly into the tear-resistant, dual progressive Nomex spiders for reliable service. The dual 4-ohm design lets you wire for high output or a multiple woofer setup. Note: If you are wiring this DVC sub for lower impedance, make sure that your amp is compatible. Most car amplifiers are stable down to 2 ohms in standard mode, or 4 ohms in bridged operation. Alpine SWSD owner's manual. Average review: 9 reviews. Thanks for taking the time to share your experiences with other customers.
Please see our review guidelines for help and information. By submitting this review, you agree to our terms and review guidelines. Features Specifications. Kevlar adds strength and tear resistance to the woofer cone while maintaining the benefits of a pulp cone design.
There is also an oversized aluminum coated polypropylene inverted parabolic dust cap, which increases rigidity and virtually eliminates distortion at extreme volume levels.
The surround is specially designed to resist deformation that is common in most woofers with wide surrounds. This design gives the surround more control over the woofer cone to reduce distortion and possible driver failure. Screw Cover Gasket: The woofer includes a rubber gasket to cover the screw holes. Dual voice coil woofers offer flexibility in wiring.
When the voice coils are wired in parallel with each other, the woofer presents a 2 ohm mono load. When the voice coils are wired in series with each other, the woofer presents an 8 ohm mono load. In addition, each coil may be connected to a different amplifier channel and each channel will see a 4 ohm load. Spring Posts: The woofer has two pairs of spring posts which will accept pin connectors, banana plugs, and up to 8 gauge bare wire. All four speaker terminals are located on one side of the woofer to make it easier to connect the woofer in a parallel or series configuration.
These jumpers allow you to wire the voice coils in parallel for a 2-ohm load or series for an 8-ohm load. Mirrored Progressive Nomex Spiders: This subwoofer has mirrored progressive Nomex spiders for added stability and mechanical durability. The custom progressive rolls gives the woofer a longer, more linear stroke with maximum centering and restoring force.
Special edge control design and Nomex construction provide excellent tear resistance, strength and long-term reliability. The tinsel speaker leads are integrated into the top spider.
Heavy Gauge Steel Basket: The frame is custom stamped from heavy gauge steel for maximum strength. Two vertical slits are cut into each of the six "legs" of the basket below the spider to allow cool air to flow in and heated air to flow out.
Heat Transfer Plate: This subwoofer contains a heat transfer plate that is thermally coupled to the voice coil. Bumped Back Plate and Extended Vented Pole Piece: This woofer combines a bumped back plate and an extended pole piece, giving it a nearly 2" peak-to-peak cone excursion. This extra long cone movement provides a higher bass output. The vents and dual flared design of the pole piece maximize airflow around the voice coil, giving it a more reliable performance. Within this range, the ideal size recommended by Alpine is 1.
One 4" diameter x 12" long port should be used with the 1. SpeakerCompare simulates the sound of home and car speakers through your headphones. It lets you compare sonic characteristics between speakers so that you can make a more informed shopping decision.
