Affordable Alpine Type-E subwoofers will fill up your ride with big bass without draining your bank account. These low-profile subs handle plenty of power, and still use the same tried-and-true design that's made this line so popular with budget-conscious bassheads.

The 4-ohm SWE-1243 12" subwoofer handles up to 250 watts RMS. Alpine treats the two-layer pulp cone with Kevlar so it won't buckle or distort under heavy use, while the tough Santoprene rubber surround keeps your cone under control for more accurate bass. Extra venting maximizes air flow through your speaker, dissipating heat and increasing your sub's reliability. The heavy-gauge, stamped steel cage holds its shape through the most relentless pounding, so your bass stays tight.

Two trim options allow you to hide your mounting hardware. Use the gasket cover for a simple, unadorned look, or frame your sub with the impact-resistant protective grille.

Get a great deal on this sub when you put together a system. Check out this Alpine dual 12" bass package.

Features

Woven Fiber/Kevlar Reinforced Pulp Cone: This Alpine Type-E subwoofer features a two-piece parabolic woven fiber and Kevlar reinforced pulp cone. Kevlar adds strength and tear resistance to the woofer cone while maintaining the benefits of a pulp cone design. The lightweight cotton fiber design provides a faster and more dynamic response from the woofer.

Santoprene Rubber Surround: The high-excursion, tapered half-roll, injection molded Santoprene rubber surround is durable and resistant to the elements, resulting in a very reliable performance. The surround is specially designed to resist deformation that is common in woofers with wide surrounds. This design gives the surround more control over the woofer cone to reduce distortion and possible driver failure.

Progressive Nomex Spiders: This subwoofer utilizes a Progressive Nomex spider for stability and mechanical durability. The custom progressive roll 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.

Voice Coil: The Alpine SWE-1243 features a 4-layer single voice coil made from 180-degree high-temperature wire wound on an aluminum bobbin.

Airflow Optimized Extended/Vented Pole: This SWE-1243 features an extended pole piece which provides optimum airflow for the woofer.

Custom High Strength Steel Basket: The frame is custom stamped from high strength steel.

Speaker Terminals: This Alpine Type-E subwoofer features a pair of heavy duty push-terminals on one side of the woofer's basket that will accommodate up to 8-gauge speaker wire.

Tinsel Leads: The Type-E subwoofer uses insulated 16-gauge stranded tinsel leads.

Gasket Cover: Alpine uses a Concealed Mount Gasket System to cover the mounting screws for a clean look. The black rubber gasket ring comes already installed on the woofer and needs to be removed before drilling the mounting screws (not supplied). The gasket ring then snaps back into place once the woofer is mounted.

Protective Grille: The Alpine SWE-1243 Type-E subwoofer comes supplied with a high impact protective grille. The black plastic grille snaps onto the woofer without the need for any additional hardware. The rubber gasket cover must be removed when using the grille. The grill also hides the mounting screws, as well as protects the woofer. The grille adds 0.9425" to the woofer's height (1.6875").

Enclosure Compatibility
