Alpine SWR1243D

New and Improved Alpine Type-R:

Delivering the best bass output, the Alpine SWR-1243D has been redesigned to enhance audio playback and become your ideal sound system. Type-R's new depth design offers a 20% reduction while adding the new and improved magnet structure. With this updated double-stacked strontium magnet, this product gains over 20% more motor force to provide a louder, cleaner bass. The optimized CRC machined motor creates an even magnetic field to provide the user with less distortion and overall improves the subwoofers power handling. This subwoofer features a High-Amplitude Multi Roll (HAMR) to provide excellent excursion with overall better output. Having a new and improved airflow management system controlling the temperature of the voice coils, the air is redirected across the heatsink to avoid overheating. With heavy playing time, this heatsink feature minimizes the amount of compression to reduce any heat damage to the voice coils giving you a long-lasting subwoofer.
