About the Alpine SPR-50
Exceptional performance, even at high volume
Like it loud? Alpine designed their Type-R speakers for people who like to turn it up. They'll deliver big, dynamic sound with plenty of bass, and they'll handle lots of volume. They'll work great with your car stereo, but they really come into their own when you power them with an outboard amp.
Fine-tuned for clarity and balance
The SPR-50 5-1/4" speakers feature multi-layer hybrid fiber woofer cones that deliver really strong bass response. Alpine's adapted the specially ridged surround, originally developed for their subs, to these speakers, so you get consistent, extended cone movement that pushes a lot of air. The silk tweeters produce smooth highs that bring out your music's detail and depth with no shrillness. Alpine mounts an EQ ring in front of the tweeters to help disperse the highs for a larger listening "sweet spot" in your ride. Plus, you can swivel the tweeters to focus the sound better for your seating position.
Smaller, stronger neodymium magnets
Alpine uses powerful neodymium magnets which are much smaller than traditional magnets, so the SPR-50's high-density polymer frames will fit into more places than most 5-1/4" speakers. Type-R speakers have earned their reputation in the past as the masters of "crank it to the max," but Alpine has really kicked the performance factor of the latest models up a notch or two.

Woofers: The Alpine Type-R series coaxial speakers feature multi-layered hybrid fiber woofer cones. For durability and superior linearity, the woofers use rubber surrounds.
HAMR Surround: 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.
Swiveling Tweeters: 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.
Neodymium Magnet: 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.
