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
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
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 applications.
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, high-strength design.
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 3-1/4" deep, this 10" sub provides deep bass performance where it
normally couldn't fit. And the 0.35 cu/ft ideal sealed enclosure size
(or 0.6 cu/ft ideal vented enclosure size) means great bass performance
can go just about anywhere in your vehicle.
Recommended Sealed Box Volume: The recommended sealed box sizes range from 0.25 cu/ft to 0.5 cu/ft. Within
this range, the ideal size is 0.35 cu/ft.
Recommended Vented Box Volume: The recommended vented box sizes range from 0.5 cu/ft to 0.75 cu/ft. Within
this range, the ideal size is 0.6 cu/ft. A slot port with the following
dimensions should be used: 3.625" (W) x 2" (H) x 24.5" (L).
