SWR-8D4 - 8′′ (20 cm) Subwoofers (4Ω + 4Ω)
These redesigned, fifth-generation Type-R subwoofers include several enhanced features to achieve even cleaner, deeper bass extension, faster, more accurate transients and even greater output capability than before.
The new FEA-Optomized Motor Structure together with our revolutionary High-Amplitude Multi Roll (HAMR) Suspension Design gives the new Type-R Subwoofers the highest X-max and SPL output in the category.
With a real-world, measured 12 mm of X-max, allow the new 8” (20cm) Type-R Subwoofers to deliver the best-in-class bass output, ultra-low distortion, and unparalleled sound quality.
The oversized 38 mm voice coil allows for increased power handling of 350W RMS / 1000W Peak. To get the best performance, we recommend you pair Type-R subs with Alpine’s new PDX digital amplifiers.
