Pioneer TS-SW2501S4 10-Inch Step Up Shallow S4 Subwoofer

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-SW2501S4 Features

Interlaced Basalt/Carbon Fiber Reinforced IMPP Cone
To ensure that you get more natural bass, we've incorporated out new Basalt fiber technology into our shallow subwoofers. The volcanic-rock fibers create a cone that is lightweight, rigid, well damped, stable in temperature extremes, and more environmentally friendly. In short, this bass really rocks.

3-Layer Radial Surround
A sub's surround plays a key role in its overall performance. In order for bass response to be clear and tight, the surround has to respond evenly around its entire circumference without flexing or puckering, even at high volume levels. That's why Pioneer created a surround consisting of two layers of urethane, with a layer of interwoven fiber between them. It's strong, stable, and it reduces distortion.

Spring-Compression Binding Posts
Why does Pioneer use Spring-Compression Binding Posts, instead of standard speaker wire terminals? So your speaker wire NEVER shakes loose due to vibration (either from the road or from your music). When you insert the wire, the connector keeps a constant pressure on it. And it won't let go. These binding posts will accept wire as large as 8-gauge.

Add Newly Designed Spoke Grilles
Protect your subwoofer with the UD-G308 grille. This stylish spoke grille is a must add-on when building a system and gives the look of pure professionalism.
