Product Description

Amazon.com Product Description

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.

5.0 out of 5 stars Runs fine free air too and sounds like a 10", June 6, 2011

This review is from: Pioneer TS-SW841D 8 In. Shallow-Mount Subwoofer with 500 Watts Max. Power (Electronics)

I have only one of these mounted on my rear deck shelf. It's a stealth install and you can't tell it's there till you hear it. It sounds great. I was thinking it might not sound too good without a box but it seems to sound just fine mounted on the underside of my rear deck. My amps crossover is set at 100Hz and I am running 300 watts RMS to it. It sounds great. This is not a sheet metal vibrator type of sub. It provides clear, deep accurate bass at an affordable price. If you want teenage level madness like you hear at some stop lights with the sheet metal vibrating etc.... than get a 12" woofer. This 8" sub packs in plenty of undistorted low frequency tones and the mounting options, well with this low installation depth of 2.5" there are many possibilities out there. Again, I'm only using one of these in my Lincoln and it sounds great. I'm not necessarily advocating free-air installation as the best option but in my particluar set up it was required to keep the install totaly stealth. It does sound great though so in my case it worked out just fine. This 8" sounds more like a 10".

I bought this replace a factory sub in my vehicle and even though I don't crank it like I did when I was 16, it has good sound and a nice range of bass tones. Definitely a good pick for anyone looking for a shallow-mount sub.

This review is from: Pioneer TS-SW841D 8 In. Shallow-Mount Subwoofer with 500 Watts Max. Power (Electronics)

I went with a completely invisible subwoofer install by putting this in a box under the rear floor of a VW GTI. The box is very shallow. I run two channels of a small Sony amp supplying exactly the 140W or so that the speaker's owner's manual calls for. I had a sound shop run the wiring for all the components I had assembled. They admitted some serious surprise with the end result (although having a hatch back helps in that regard - might not be as impressive in a sedan trunk).

Overall, very happy. More bass support than I needed or thought possible from my install.
