Features & Specifications



Alpine R2-W10D4 R Series 10″ Subwoofer with Dual 4-Ohm Voice Coils

In the world of car audio enthusiasts and bassheads, Alpine stands as a legendary name with over four decades of experience in delivering high-quality sound experiences. Among their impressive lineup, the Alpine R2-W10D4 R Series 10″ Subwoofer with Dual 4-Ohm Voice Coils shines as a true powerhouse in the realm of subwoofers. In this article, we’ll dive deep into what makes this subwoofer a standout choice for anyone seeking hard-hitting bass with precision and clarity.

The Alpine Legacy: 40 Years of Excellence

With a history dating back to the 1970s, Alpine has amassed a wealth of knowledge and expertise in crafting audio systems that elevate your listening experience. The R2-W10D4 10″ subwoofer is a testament to this legacy, designed to deliver bass that not only hits hard but also maintains exceptional sound quality.

A Magnificent Motor Structure

One of the key features of the R2-W10D4 subwoofer is its innovative motor structure, which includes double-stacked magnets. This unique design element serves a crucial purpose – to provide deeper bass and a tighter sound response. When you’re craving that bone-rattling thump in your music, this subwoofer has got you covered.

Kevlar Reinforcement for Durability

The heart of any subwoofer is its cone, and Alpine has taken it a step further with a Kevlar-reinforced pulp cone. Kevlar, known for its exceptional strength and resilience, ensures that the cone can handle intense vibrations and deliver consistent performance over time.

HAMR Santoprene Surround

To enable substantial excursion, Alpine has equipped the R2-W10D4 with a HAMR Santoprene surround. This rubber surround not only allows for impressive cone movement but also maintains its durability in the face of heavy bass output. It’s a crucial component in achieving that deep, impactful bass response.

Oversized Poly Ceramic Dust Cap

Rigidity is paramount when it comes to bass reproduction, and Alpine has addressed this with an oversized poly ceramic dust cap. This cap ensures that the subwoofer remains stable even during the most demanding bass-heavy tracks, contributing to the overall tightness and accuracy of the sound.

Power and Flexibility

The Alpine R2-W10D4 doesn’t just excel in terms of design and build; it’s also a versatile performer in terms of power handling and wiring options.

Impressive Power Handling

This subwoofer can handle an impressive 750 watts RMS (Root Mean Square), making it compatible with high-powered amplifiers. Its peak power of 2250 watts ensures that it can handle intense bursts of bass without breaking a sweat.

Dual 4-Ohm Voice Coils

One standout feature of the R2-W10D4 is its dual oversized 4-ohm voice coils. These voice coils provide wiring flexibility for various subwoofer setups, allowing you to customize your audio system to your liking. Whether you prefer a single subwoofer or a multi-sub setup, this subwoofer can adapt to your needs.

Enclosure Options

Another advantage of the R2-W10D4 is its compatibility with different enclosure types. Whether you prefer a sealed or ported enclosure, this subwoofer can deliver the sound you desire. It’s all about tailoring your car audio system to your personal preferences.

Note: If you decide to wire this Dual Voice Coil (DVC) subwoofer for lower impedance, it’s essential to ensure that your amplifier is compatible with the chosen configuration.
