The R2-S65 is the 2-Way Coax model of the new 2022 R-Series speaker line-up. It features a 16,5cm door woofer as well as an integrated tweeter with up to 40kHz frequency response. The door woofer features an all-new glass-fiber reinforced cone. This material is very stiff and extremely light-weight, resulting in a super-fast response and highly accurate music reproduction. The all-new magnesium hard-dome tweeters deliver clear, detailed music reproduction and play up to 40kHz (Hi-Res Audio). The Coax-tweeters can be swiveled in their housing to point them right at the sweet-spot. Alpine’s HAMR Surround (High-Amplitude Multi-Roll) allows for a maximum cone excursion, while maintaining excellent control. This results in strong bass at high volumes without distortion. 16.5cm Door Woofer (2pcs) with Integrated Coax Hard-Dome Tweeters Composite Baskets (Door Woofer) Glass-Fiber Reinforced Cone (Door Woofer) Integrated X-Over Networks Included Speaker Grills Maximum Peak Power: 300 Watts Maximum RMS Power: 100 Watts Nominal Impedance: 4 Ohm Frequency Response: 65Hz-40kHz Sensitivity: 88dB SPL (1W @ 1m) Woofer Mounting Depth: 6,3cm Woofer Cutout Diameter: 13,5cm
