The high-performing Type-R models have been upgraded for 2012, offering
even more power up to 1000W RMS to accommodate large amplifiers and big
systems. These durable subwoofers provide class-leading output and
sound quality, thanks to Alpine’s exclusive patented technology that
reduces distortion and maximizes musical detail. Their H.A.M.R.
surround and powerful CRC motor structure designs provide well over 2
½-inches of peak-to-peak excursion and up to 20 mm linear Xmax for
incredibly deep and clean bass.
