S2-W8D2/D4 by Alpine

The new generation of S-Series subwoofers
Give your sound system an extra boost now with the new 20 cm S-Series Subwoofer S2-W8D2. The subwoofer was designed for powerful, stable bass performance at an affordable price.

Performance & Power
With an impressive power handling of 300 W RMS and a peak power rating of 900 W, the 8-inch subwoofers deliver excellent performance. With a wide frequency range from 35 Hz to 215 Hz and a sensitivity of 83 dB (SPL@1 W/1 m), these subwoofers provide powerful and precise bass reproduction across many music genres.

H.A.M.R. Surround
The new S-Series subwoofers feature Alpine High Amplitude Multi-Roll (H.A.M.R.) surround technology. This rubber surround ensures the subwoofer cone moves air efficiently while maintaining stable control. This technology allows an excursion of up to 10 mm in one direction, resulting in incredible power handling for the subwoofer.

Best combination of materials
The lightweight yet durable combination of carbon fiber and polypropylene delivers deep, low-distortion bass that highlights the depth and richness of your music.

Flexible applications
A dual voice-coil (DVC) with convenient plug-in jumpers allows many applications for the S-Series subwoofers. A new twist-lock grille mounting system for additional protection of the cone enables the easy fitting and removal of an optional protective grille entirely without mounting screws.

Perfect amplifier performance
Maximize the potential of your S-Series subwoofers with Alpine's perfectly matched S-Series amplifiers. Effortlessly, you can power an S2-W8D4 subwoofer with the 600-watt mono amplifier S2-A60M, or connect one or more S2-W8D4 subwoofers to the powerful 1200-watt amplifier S2-A120M. This guarantees optimal sound quality and stable performance.

Sizes & Variants
The new S-Series subwoofers are available in 12-inch, 10-inch and 8-inch sizes and are offered with 2x 2Ω and 2x 4Ω impedances.

Speakers for S-Series Amplifiers & Subwoofers
The S-Series speakers are perfectly matched to Alpine S-Series amplifiers and subwoofers to create a perfectly tuned system. The S-Series components were developed for customers who want to build a great-sounding high-res audio system without breaking the budget.
