The redesigned, fourth-generation Type-R subwoofers include several enhanced features to
achieve even cleaner and deeper bass extension, faster and more accurate transients, and
greater output capability.

New Technologies Improve Bass Sound
A new FEA Optimised Motor Structure together
with exclusive High Amplitude Multi Roll (HAMR)
suspension results in the highest X-max and SPL
output in the category. Alpine’s Compound Radius
Curve pole geometry provides an ultra symmetrical
magnetic field, while optimising flux density for
lower distortion with higher power handling. Alpine’s
Radial Vented VC Heatsink and Airflow Management
System helps to minimise power compression and ensures long playing time by
actively moving output-robbing heat away from the voice coil.

Exclusive Alpine Technologies Ensure High
Performance
The new Type-R Flat boasts no less than seven
unique Alpine technologies in its industry-first
design. These innovations allow it to have the
output and power handling of the traditional
Type-R series in less than half the depth. The
design has the same DNA of the standard
Type-Rs, for cleaner, deeper bass extension,
faster, more accurate transients and even
greater output capability.

Superior Bass Performance
Even though the previous Type-R subs
set high standards, the new models have
over 20% more motor force, delivering
louder and cleaner bass with even greater
accuracy. The oversized 65mm voice coil
offers 35% more surface area, allowing for
increased power handling.
Flatter, Yet Powerful
These subs have been engineered to offer more installation flexibility and application
versatility to build the ideal sound system. With 8.3cm depth for the 25cm model
and 9cm depth for the 30cm, they provide deep bass performance where it normally
couldn’t fit. And the 10 litre (SWR-T10) and
17 litre (SWR-T12) ideal enclosure sizes
mean great bass performance can go just
about anywhere in your vehicle.
With their increased power handling and SPL, as well as
lower distortion, we recommend you pair Type-R subs
with the new PDX digital amplifiers.
The Type-R Flat subwoofer series delivers intense
low-bass performance in a thin package optimised for
extremely small enclosures.
