Alpine SPR-60 Type-R 6-1/2" to 6-3/4" 2-way car speakers
The Alpine Type-R series coaxial speakers feature multi-layered hybrid fiber woofer cones. For durability and superior linearity, the woofers 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 speakers are equipped with 1" (25mm) silk dome tweeters. Alpine's EQ Ring improves the tweeter's dispersion characteristics, providing excellent off-axis response. You can also tilt the tweeters up to 15 ° to focus the sound where it should be, not pointed at your feet.
The new smaller neodymium magnet on the Type-R series allows the speaker dimensions to be smaller, 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 speakers use a revolutionary HD Polymer frame, making the speaker stronger, lighter, and easier to install.
Out of the box the SPR-60 is a 6-3/4" speaker. Using the included brackets they are also compatible with standard 6-1/2" applications.
