Alpine Type-R Thin Subwoofer: The Alpine Type-R Thin subwoofer series combines the low-bass performance and
power handling of Alpine's traditional Type-R subwoofers in a thin package
optimized for extremely small enclosures. The new Type-R Thin boasts no less
than 7 unique Alpine technologies in its industry-first design. These
innovations allow the Type-R Thin to have the output and power handling of the
traditional Type-R series in less than half the depth. The new Type-R Thin
design has the same DNA of the standard Type-Rs; demanding cleaner, deeper bass
extension, faster, more accurate transients, and even greater output capability.
Parabolic Aluminum Cone with Force Transfer Assembly: A Heavy-duty magnet assembly calls
for heavy-duty cone materials, such as parabolic aluminum cone woofer. This
specially engineered aluminum cone is reinforced by an injection-molded force transfer
assembly, giving the cone structure outstanding stiffness while minimizing
moving mass. A centering ring in the force transfer assembly is also engineered
to lock the voice coil assembly in place. This makes the entire piston assembly
extremely strong and linear.
FEA Optimized HAMR Surround: The High-Amplitude Multi Roll (HAMR)
Surround Design allows for extreme excursions without sacrificing valuable cone
area. FEA Optimized for linearity and made with injection-molded Santoprene ,
the HAMR surround is a key part of the suspension system that provides accurate,
distortion-free control at extreme excursions.
1.5lb Neodymium Magnet with 4" Voice-Coil: The Type-R Thin subwoofer's
1.5lb neodymium magnet has 5x the magnetic strength than standard ferrite
magnets used for most subwoofers. This powerful magnet combined with a massive
4" (100mm) voice coil delivers increased power handling and more accurate,
louder, cleaner bass with even more control.
Segmented Spider Design: You can count on Type-R Thin subwoofer to
deliver strong, impactful output like its predecessors. Its Revolutionary
Segmented Spider Design provides the Excursion of a tall subwoofer. Most
shallow-mount subwoofers have less output than traditional deep subwoofers,
since their shallow frame limits how far their cones can move at high power
levels. The Type-R Thin subwoofer uses Alpine's patent pending Pass-Through Gap
Geometry, allowing the unique Thermoplastic Elastomer Segmented Spider to
completely pass through the motor structure. This means the cone and voice coil
assembly have the clearance needed for over 50mm of peak-to-peak excursion,
allowing for massive output even in such a shallow frame.
FEA Optimized Dual-Sided Machined CRC Motor Structure: An FEA
Optimized Dual-Sided Machined CRC Motor Structure creates a symmetrical magnetic
field with evenly distributed flux density to greatly reduce distortion, while
further improving power handling and output.
Radial Vented VC Heat Sink & Airflow Management System: Alpine's
Patented Radial Vented VC Heat Sink and Airflow Management System (helps to
minimize power compression and ensures reliable long playing time by actively
pulling (or transferring) output-robbing heat away from the Voice Coil.
Cast Aluminum Frame: The new cast aluminum frame is directly coupled
to the machined aluminum shorting sleeve assembly. This allows the entire frame
to act as a heat sink for sustained power handling, even in the most extreme of
Speaker Terminals: This Alpine Type-R Thin subwoofer
features a pair of heavy-duty screw-terminals on one side of the woofer's basket
that will accommodate up to 8-gauge speaker wire. A hex-key is provided to
adjust the set-screw terminals.
Gasket Cover: Alpine uses a Concealed Mount Gasket System to
cover the mounting screws for a clean look. The black rubber gasket ring comes
already installed on the woofer and needs to be removed before drilling the
mounting screws (not supplied). The gasket ring then snaps back into place once
the woofer is mounted.
No Break-in Period: There's no need to play your sub for hours to
break it in to achieve consistent performance. This sub is designed to deliver
consistent performance right out of the box. Since this revolutionary design is
made with an injection mold resin, rather than phenolic stiffened textile, this
new spider requires no break-in to achieve ideal performance. A Co-Molded
Aluminum collar attaches the voice coil to the spider to ensure a reliable,
Thin Mount: The Alpine Type-R Thin series subwoofer has been
engineered to offer more installation flexibility and application versatility to
build the ideal sound system. At 3-1/2" deep, this 12" sub provides deep bass
performance where it normally couldn't fit. And the 0.6 cu/ft ideal sealed enclosure size
(or 1.0cu/ft ideal vented enclosure size) means great bass performance can go just about anywhere in your
Recommended Sealed Box Volume: The recommended sealed box sizes range from 0.4 cu/ft to 0.75 cu/ft. Within this
range, the ideal size is 0.6 cu/ft.
Recommended Vented Box Volume: The recommended vented box sizes range from
1.0 cu/ft to 1.5 cu/ft. Within this
range, the ideal size is 1.0 cu/ft. A slot port with the following dimensions
should be used: 3.625" (W) x 3.5" (H) x 28.75" (L).
