Air Suspension System

In order to create a subwoofer that is three & a quarter inches deep, Pioneer had to develop revolutionary subwoofer technology. A traditional subwoofer uses the spider design to keep the voice coil of the speaker aligned while it moves. This type of set-up can become soft over time degrading the subwoofer’s performance. Pioneer created a patent-pending air suspension system that locks air between a main cone & a drive cone. The cones move together in unison, w/the locked-in air behaving like a spring. The dual-cone structure is a spider-less design that maintains better sound linearity, & reliability even after many of hours of hard use.


The pressure from the trapped air results in a consistent bass response across a wide frequency range. The result is a tight, precise movement w/powerful & clean bass output.


3-Layer Interwoven Radial Surround

The shallow subwoofer incorporates an innovative woven cloth reinforced radial urethane surround for improved power handling, reduced distortion, improved durability, & louder, more controlled bass. The surround is constructed of three layers — two of urethane & one of interwoven cloth. The interwoven cloth distributes strength throughout the surround material & improving its high power capability. The result is an extremely durable & resilient surround that resists puckering, even under intense power conditions.


Unlike traditional surrounds that use a single arch shape design, the Pioneer Shallow Subwoofer utilizes a patent-pending M-shape surround that provides superior sound linearity.


M-Shaped Surround

The M-shape surround also has a lower height, & a lower fc or tuning frequency. The lower fc threshold translates to better & longer performance at lower frequencies.


Angled Push Terminals

Traditional subwoofer terminals are mounted horizontally or vertically. These mounts force wires to be bent to fit which can be difficult if low-gauge high performance wires are used. The Pioneer shallow subwoofer’s patent-pending, angled push terminals make it easy to connect speaker wires. The straighter connection saves space & makes installation easier.


Fin-Shaped Basket

Traditional subwoofers push air downward. This creates a “loading effect” or area of pressure underneath the speaker which hampers performance & responsiveness. The rear of the powerful & slim Pioneer shallow subwoofer is designed w/specially-shaped fins that channel the airflow sideways instead of downward. Air is continuously pushed in a circular motion, eliminating the “loading effect” or unwanted pressure of air behind the cone.
