Product information "Alpine R-W12D2 - 30cm Subwoofer"

The redesigned Type-R subwoofers of the current generation, with advanced parameters for a precise and punchy bass extension, ensure fast and accurate bass reproduction in your vehicle.

The next level of best performance
The new R Series subwoofers offer you the next level of development. These Type-R subwoofers come from the legendary R series subwoofer series, known for their power, clean reproduction and superb bass quality. While retaining the successful Type-R subwoofers, we have used various improvements in performance and material, with a new design. This will take you to a new level of Type R subwoofer - the next level of best performance.

Stable drive structure
The R series subwoofers have a long life, Kevlar coated membrane. The connection of the diaphragm to the suspension made of Santoprene allows the subwoofer an X-max of 19 mm and therefore offers an incredibly powerful bass. A new technology for mounting the spider and diaphragm on the voice coil not only ensures the rigidity of the entire drive structure but also contributes to clean bass response.

Improved dust protection membrane
Talc, a very common mineral used in products such as baby powder and paint, provides an incredible cushioning effect while being significantly lighter than the traditional mica filler used in dust caps. By adding a precisely calculated amount of talc in the dust cap, we were able to increase vibration damping and thereby reduce weight. The resulting lighter dust cap improves the accurate reproduction of low frequencies.

Optimal power consumption
All four R Series subwoofers have a nominal output of 750 W RMS. These subwoofers fit perfectly for an efficient system to the mono amplifier PDR-M65. There are four subwoofer R series models:R-W12D4 (12-inch) 2 x 4 ohms, R-W12D2 (12-in) 2 x 2 ohms, R-W10D4 (10-in) 2 x 4 ohms and R-W10D2 (10 inches) 2 x 2 ohms.
