Alpine 8" Type-R Series Dual 2-Ohm Black Subwoofer, Model SWR823D
At only 4.5 inches deep and 8 inches in diameter, the new Type-R 8-inch subwoofers
(SWR-0823D and SWR-0843D) are ideal for cramped quarters. Ideal for installation
in door panels, trucks, or other tight spaces, the 8-inch subwoofers use technologies
found in Type-R subwoofers and incorporate them in a smaller package. The 8-inch
subwoofers have over 14mm of linear excursion for high output in small ported
or sealed enclosures and handle up to 350W RMS.
Type-R subwoofers are proven and durable. Besides the new 8-inch size, Type-R
subwoofers come in 10-inch (SWR-1023D and SWR-1043D), 12-inch (SWR-1223D and
SWR-1243D) and 15-inch (SWR-1522D and SWR-1542D) models. Known for clean, deep
bass and low frequency extension in small enclosures, these popular subwoofers
are dependable performers. Using Alpine’s patent pending High-Amplitude Multi
Roll (HAMR) surround and patented thermal management technology, the Type-R
subwoofers run with cooler operation, higher output and longer life.
The Type-R subwoofers all have large, high temperature voice coils which allow
for increased power handling, making them ideal for pairing with the Alpine
PDX digital amplifiers. The HAMR surround design also allows for extreme excursion
without sacrificing cone area. The subwoofers are constructed from a single
piece cast aluminum frame and shorting sleeve, for a unique design that provides
minimum inductance variance and reduced thermal compression. Cooling of the
entire motor assembly is achieved from the innovative radial fins, leading to
maximum cooling of the voice coil and reduced thermal compression.
