The woofers have a large, 35-millimeter (mm) voice coil which allows for greater heat dissipation, increased motor force, and improved power handling. The result is superior control and output.
The R-Series speakers incorporate Alpine’s patented High-Amplitude Multi-Roll Surround (H.A.M.R.) for control and accuracy. The component models use a crossover with an in-line, passive design and reduced footprint, which contributes to easier installation.
