Alpine SPR-60C Type-R 6-1/2" to 6-3/4" Component Speaker System
The Alpine Type-R series component speakers feature multi-layered hybrid fiber woofer cones; for durability and superior linearity, they use rubber surrounds.
Type-R speakers use Alpine's multi roll HAMR surround (patent pending), a technology developed for Alpine subwoofers that maintains control and stability at higher volume levels. HAMR surround combines increased cone area and long linear cone excursion for deep, powerful bass response.
The woofer's High-performance Linear Drive Motor structure features a square-wire voice coil with a large 30mm diameter, driven by a small but powerful neodymium magnet. This design provides linear motion over a wide cone excursion.
The neodymium magnet on the Type-R series woofers allows smaller speaker dimensions, making them easier to install in a wide variety of vehicles. They are also lighter than designs using standard magnet technology.
HD Polymer Frame
The new Type-R woofers use a revolutionary HD Polymer frame, making the speaker stronger, lighter, and easier to install.
The SPR-60C includes 1" (25mm) silk dome tweeters. Alpine's EQ Ring improves the tweeter's dispersion characteristics, providing excellent off-axis response. When using the flush-mount housing you can also tilt the tweeters up to 15 ° to focus the sound toward your ears.
Tweeter Mounting Options
The tweeters come installed in a swiveling flush-mount housing. You can also install the tweeters behind factory grilles using the included stealth mount brackets. The stealth mount brackets can be top or bottom mounted.
