New series

Whilst the big, space-hungry subwoofer has epitomised the conventional car entertainment market for years, a new series of slim-line subwoofers from Pioneer delivers full, deep bass in less space.

Utilising new audio patent technology to manufacturer it largest range of slim-line subwoofers for the car, Pioneer challenges the assumption that big bass needs big space.

The new slim-line subwoofers include Pioneer’s TS-SW2501S4, TS-SW2501S2, TS-SW30001S4 and TS-SW30001S2, a complete range of 12, 10 and 8 inch models.

The slim-line Pioneer subwoofers feature multiple patent-pending features to deliver the big bass performance of a full-size subwoofer, but in a compact design that can be installed in a variety of different positions in the car, depending on the type of vehicle and the installation conditions.

The mounting depth is just 3-1/4" or smaller - less than half a typical subwoofer in this class.

“As a leading in-car subwoofer brand, we appreciate different vehicle types offer varying available space for installation of a subwoofer. Especially in a car where space is extremely limited, size does matter. Pioneer has developed three different subwoofer sizes to fit a variety of vehicles and provide plenty of installation choices. Our 12” and 10” models can be installed behind or under seats, while the 8” type can also fit on the rear side wall or rear tray of many vehicles,” said Paul Baddeley, head of product management for the mobile electronics group at Pioneer Electronics Australia Pty Ltd.
 
Venturing to go where most conventional subwoofers struggle to go, Pioneer’s TS-SW2501S4, TS-SW2501S2, TS-SW30001S4 TS-SW30001S2 slim-line subwoofers are packed with cutting-edge technology to ensure high quality bass.

Utilizing innovative and patented designs, Pioneer has continued to change the face of the subwoofer industry.

“To ensure that you get more natural bass, we’ve incorporated out new Basalt fibre technology into our slim-line subwoofers. The volcanic-rock fibres create a cone that is lightweight, rigid, well damped, stable in temperature extremes, and more environmentally friendly. In short, this bass really rocks”, added Baddeley.

Air Suspension Control System
One of the new patent-pending features is called the "Air Suspension Control System". This design locks in air between the main cone and drive cone, ensuring smoother and more precise movement of the cones, for superior linearity. The locked-in air behaves like a spring, so there's no need for a traditional spider structure. The drive cone also deflects air pressure inside the enclosure, which further contributes to the remarkable bass of the small package.

Low and Steady
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. The M-shape surround also has a lower height, and a lower resonant frequency. In short, this enables the sub to perform better and longer at lower frequencies, resulting in low, steady bass.

Durable Surround
The shallow subwoofer surround is constructed of three layers — two of urethane and one of interwoven cloth. The interwoven cloth distributes strength throughout the surround material: improving its high power capability and durability, reducing distortion, and producing louder, more controlled bass.
 
Angled Terminals
Traditional subwoofer terminals are mounted horizontally or vertically. These mounts force wires to be bent in order 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.

Fins Make Everything Cooler
Traditional subwoofers push air downward. This creates a “loading effect” or area of pressure underneath the speaker which hampers performance and responsiveness. The rear of the powerful and slim Pioneer shallow subwoofer is designed with 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.
