Pioneer Shallow Subwoofers Equal Deep Bass in Small Space

New ib-Flat Subwoofers and Complementing Enclosure Line Now Available

Pioneer Electronics (USA) Inc. today introduced the TS-W3002S4 12-inch, TS-SW2502S4 10-inch, and TS-SW2002D2 8-inch ib-Flat shallow subwoofers, designed for small enclosures and limited depth applications while still producing strong musical bass output. Pioneer’s fourth generation shallow subwoofers are completely re-engineered to provide increased output, higher power handling, higher sensitivity, more installation flexibility, and improved cosmetics.

ib-Flat Shallow Subwoofers
Designed especially for consumers who want to add more of the critical bass frequencies in the bottom three octaves (20Hz-160Hz) but do not have the room or desire to install a traditional large subwoofer enclosure in their vehicles, Pioneer’s next generation ib-Flat shallow subwoofers have a mounting depth of less than 3.25-inches and require only a small enclosure to reach their optimum performance. The line of subwoofers feature:

  • Convex Oversized Mica Reinforced IMPP Cone – The ib-Flat woofers use a highly rigid, convex shaped cone structure made with mica reinforced injection-molded polypropylene (IMPP) resin to create an extremely stiff and durable cone while reducing the moving mass.
  • Dual Spider Suspension – The fourth generation ib-Flat models use a dual spider suspension design to control the linearity of the voice coil structure. Dual spiders provide symmetrical and better controlled movement of the voice coil/cone, significantly increasing sound quality, power handling, and reliability.
  • 4-Layer Voice Coil – A 4-layer, heat resistant polyester resin voice coil helps dissipate heat quickly resulting in higher power handling.
  • Original Equipment (OEM) Applications – The 8-inch sized TS-SW2002D2 is outfitted with an outer basket stamped with a variety of mounting holes designed for drop-in replacement of the original equipment subwoofer in select domestic and foreign vehicles.

The Pioneer ib-Flat subwoofers are now available with suggested prices of $180 (TS-W3002S4), $160 (TS-SW2502S4) and $140 (TS-SW2002D2).

Subwoofer Enclosures
Pioneer also offers four unloaded sealed enclosures designed specifically for the ib-Flat subwoofers in both traditional and truck style designs, plus a single preloaded enclosure. The enclosure line includes the UD-SW300D (12-inch unloaded), UD-SW250D (10-inch unloaded), UD-SW200D (8-inch unloaded), UD-SW250T (10-inch unloaded truck style), and the TS-SWX2502 (10-inch preloaded with a TS-SW2502S4 ib-Flat woofer). The enclosures range in internal air volume from .15- to .5-cubic feet, factory designed to provide the maximum performance with each subwoofer.

The Pioneer ib-Flat subwoofer enclosures are now available for suggested prices of $100 (UD-SW300D), $80 (UD-SW250D), $60 (UD-SW200D), $80 (UD-SW250T) and $200 (TS-SWX2502).
