Wiring Guide

Genetically Built Like A Type-R

The new Type-E’s highly efficient design can play both louder and lower, and is more durable than its predecessor. With a shallow mounting depth, these subs can be installed just about anywhere, but they look so good, you won't want to hide them.

The Type-E cones are built with a reinforced parabolic cone structure and lightweight poly mica dust cap, enabling a faster snappy dynamic response. The high excursion Santoprene® H.A.M.R. surround allows for impressive linear excursion so Type-E subs play louder, and lower!

What is unique and amazing about the new Type-E subwoofer is not only the engineering behind the build, it's the new requirements for them to optimally perform. The new Type-E 12” specification requires 0.65 – 1.0 cubic feet air space for superior performance. That’s 35% less air space used in your vehicle!
