Alpine S2-Series 300-Watt 8-Inch Subwoofer Driver, 2Ω or 4Ω Dual Voice Coil With a power handling of 300W RMS and a peak power handling of 900W, the Next-Gen 8” S-Series Subwoofers deliver outstanding performance value. Boasting a wide frequency response range of 23Hz to 215Hz and a sensitivity of 83dB (1W/1m), these subs ensure powerful and accurate bass reproduction across a diverse range of music genres. Featuring the lightweight yet sturdy combination of carbon fiber and polypropylene, the Next-Gen S-Series Subwoofer cone delivers deep, low-distortion bass that enhances the depth and richness of your music. The Next-Generation S-Series Subwoofers contain Alpine's High Amplitude Multi-Roll (H.A.M.R.) Surround Technology. This rubber surround allows the subwoofer cone to efficiently move air while staying cool. This technology allows for 15mm of one-way excursion that creates incredible accuracy from the subwoofer. A Dual Voice Coil (DVC) with easy configuration jumpers make installing the S-Series subwoofers a breeze. A new twist-lock grille mounting system makes it easy to install and remove an optional grille without mounting screws for added protection to the cone. Maximize the potential of your S-Series subwoofers with Alpine's perfectly power-matched S-Series amps.
