120W NOMINAL POWER; 2.5" MOUNTING DEPTH; SEALED OR FREE-AIR Use

This eight-inch shallow subwoofer handles 500 watts max., 120 watts nominal power, and delivers deep bass with top-notch sound quality thanks to features like Pioneer's extremely strong and lightweight interlaced composite IMPP Cone.
Pioneer's Shallow Series Subs
Lean and Mean
The Pioneer Shallow Series subwoofer derives its big bass sound from its innovative design. Although only 3-1/4 inches thick, the Shallow Series uses state-of-the-art, patented air suspension technology to create a tight spring of pressure that delivers a wide-ranging bass response. The result is a radically thin subwoofer that fits a variety of enclosures and gives your system accurate, powerful, and satisfying bass.
"ib-FLAT"
Known as the "flat" subwoofer, the ib-FLAT name is derived from the speaker's two most outstanding characteristics. The "i" stands for intelligent design and describes the cutting-edge air-suspension technology that gives the speaker its remarkable size and strength. "b FLAT" refers to its ability to accurately and easily play 29.135 Hertz, the sound of the lowest black key on the piano and one of the most difficult to reproduce. Musical and robust, the ib-FLAT boasts an amazing range, enabling you to hear each performance on a grand scale.
Install Anywhere
The sleek design and compact size of Pioneer Shallow Series subs enables you to perform great custom installations. The Shallow Series plays perfectly in both tight and hidden spaces, providing you with the same booming bass performance of a regular subwoofer. Whether hidden or seen, the big bass sound of these versatile speakers will definitely get you noticed.



TS-SW841D Features
Air Suspension System
In order to create a subwoofer that is three and 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 and a drive cone. The cones move together in unison, with the locked-in air behaving like a spring. The dual-cone structure is a spider-less design that maintains better sound linearity, and 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 with powerful and 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, and louder, more controlled bass. The surround is constructed of three layers--two of urethane and one of interwoven cloth. The interwoven cloth distributes strength throughout the surround material and improving its high power capability. The result is an extremely durable and 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, and a lower fc or tuning frequency. The lower fc threshold translates to better and 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 and 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 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.


This 8-inch shallow subwoofer handles 500 watts.
