Features

3-way component PRO speaker
The R2-S653 is the top of the line of the new 3rd generation R-Series speaker line-up. It features a 6.5″ door woofer, 3.8″ mid-range speaker and a 1.7″ tweeter with up to 40kHz frequency response.
Hi-res audio certified hard dome tweeter
The all-new magnesium hard-dome tweeters deliver clear, detailed music reproduction and play up to 40kHz (Hi-Res Audio). You have the option to flush-mount them in their threaded housing or use the included on-dash mounts.
Die-cast aluminum basket and large magnets
The PRO models feature high-quality aluminum baskets – resulting in high stiffness and can carry heavier magnets without warping. This allowed our engineers to fit larger magnets than in previous generations while maintaining the same mounting depth.
Glass-fiber reinforced cone
The door woofer and the mid-range speaker feature all-new glass-fiber reinforced cones. This material is very stiff and extremely light-weight, resulting in a super-fast response and highly accurate music reproduction.
Easy-fit tweeter in OEM locations
You can simply remove the installation frame and the trim ring of the R-Series tweeter to minimize its overall size and diameter. The tweeter itself is then small enough to fit it in many OEM tweeter locations for a stealthy installation.
Flexible PRO X-over network
This large-size crossover network includes many high-quality components selected for best sound quality. You can adjust the mid-range speaker level by -3dB / 0dB / +3dB and the tweeter level as well by -3dB / 0dB / +3dB.
HAMR surround
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.
New speaker grills
The new speakers grills in hexagon design look very aggressive and do not increase the overall speaker installation diameter.
