Alpine SWR-12D2

Type-R 12" subwoofer with dual 2-ohm voice coils

Maximum bass output

Alpine's Type-R subwoofers will bring big bass to just about any vehicle. The SWR-12D2 12" sub features a cone made from Kevlar® treated pulp

— the same material used to make bulletproof vests — and its durable HAMR Santoprene™ surround allows for huge amounts of excursion.

This sub was built for bassheads that want the best of both worlds: accurate response and otherworldly thump.

Bring on the power

The SWR-12D2 can handle an astounding 1000 watts of RMS power, so be sure to choose a suitable amplifier as these bass monsters definitely

want lots of power. Its dual oversized 2-ohm voice coils offer the wiring flexibility you'll appreciate as your system changes and grows, so you can

always pull maximum power from your amp. It works well in sealed and ported enclosures so you can choose what kind of bass you want to hear and feel.

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 750 and 1500 watts RMS at 4 ohms.

Features

Kevlar Reinforced Pulp Cone: This Alpine Type-R subwoofer has a two-piece structural parabolic Kevlar reinforced pulp cone. Kevlar adds strength

and tear resistance to the woofer cone while maintaining the benefits of a pulp cone design. There is also an oversized inverted poly-mica dust cap,

which 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, 4-layer dual voice coils offer increased power handling to 1000W RMS / 3000W Peak.

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 bare wire up to 8 gauge, pin connectors,

or banana plugs.

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 Volume: The recommended sealed box volume ranges from 0.65 cubic feet to 1.1 cubic feet, with 0.85 cubic feet being the ideal size.

Ported Box Volume: The recommended ported box volume ranges from 1.1 cubic feet to 1.6 cubic feet. The ideal size is 1.48 cubic feet, using a

slot port measuring 12-1/2" (W) x 1" (H) x 19" (L).

CPP buys Zagato

Tue, 05 Jul 2011

Ferrari 550 GTZ - built by CPP In a move that seems to have received no coverage whatsoever, our favourite specialist car putter-together – CPP (Coventry Prototype Panels as was) – has quietly bought up Zagato. For those of you who are ‘Vlad Watchers’ this may come as no surprise. It seems that Vladimir Antonov is on a quest to buy up everything interesting there is to buy in the specialist car world (and Portsmouth FC too – no accounting for taste!), which includes funding CPP and its recent acquisitions.
