Alpine SPR-50C

Alpine introduces its new Type-R Speakers for 2011. Thanks to a smaller neodymium magnet and strong yet light HD polymer frame, Type-R speakers are compact and lighter for streamlined applications in various locations throughout a vehicle.

In terms of sound, the Type-R has taken a huge step forward with High-Amplitude Multi-Roll (HAMR) technology (patent pending), adapted from Alpine's popular Type-R subwoofers, which provides clean, high-impact bass performance. The patented linear drive motor design uses a neodymium magnet and square-wire voice coil to provide linear motion over an extremely wide excursion range. The wave guide optimizes the acoustic impedance for smooth response and enhanced vocal clarity, both on and off axis. The ring tweeter with EQ ring and copper cap enhances both detail and output, while the swivel mount allows the sound to be focused for the best in-car performance.
