About the Pioneer TS-A2500LS4
A shallow-mount sub that rocks
A shallow-mount sub that rocks
Pioneer's TS Series shallow-mount subs bring great bass to vehicles where conventional subs won't fit. Their low profile allows the use of slender enclosures that'll fit behind a truck seat or in any tight space while delivering the bass performance you need. The TS-A2500LS4 10" shallow-mount sub handles up to 300 watts with a mounting depth of just 3-3/8".
The TS-A2500LS4 features an oversized, injected polypropylene cone that moves more air and delivers accurate bass. The sub works best in a small sealed enclosure, making it ideal for fitting those tight spaces in today's smaller vehicles. Pioneer recommends the UD-SW250D downfiring enclosure or the UD-SW250T truck-style enclosure (sold separately) for use with this sub.

Features
Woofer Cone: Pioneer uses a glass fiber and mica reinforced injection molded polypropylene (IMPP) cone, making it more rigid than polypropylene alone.
Shallow Mount Woofer: Pioneer's "Shallow-Mount" subwoofers are designed to provide wider installation options for a broad range of vehicles. They can be mounted behind or under the seats of many vehicles.
Terminals: The spring post terminals will accept pin connectors, single banana plugs, or bare wire up to 8 gauge.
Sealed Box Volume: Pioneer recommends a sealed enclosure with an internal volume between 0.35 ft³ and 0.7 ft³, with an ideal volume of 0.6 ft³. Sealed enclosures provide the most control over the woofer, will handle a lot of power, and provide accurate sonic reproduction, making them suitable to all types of music.
Ported Box Volume: The recommended ported box volume ranges from 0.5 ft³ to 0.7 ft³, with the ideal size being 0.6 ft³, using a single 3" diameter x 7½" long port. Ported (or vented) enclosures typically provide better overall efficiency than sealed, maximizing bass output for a given amplifier.
Free-Air: The woofer can also be mounted in free air to a baffle board (infinite baffle, no enclosure). When mounted in free air, the power handling is reduced by 75% (to 75 watts RMS).
Measurements: When mounting the woofer without the trim ring, the dimensions change as follows:
- Mounting Height: 0.542"
- Flange Height: 0.19"
- Frame Diameter: 10.305"
The Pioneer TS-A2500LS4 replaces these items
- 10" 4-ohm shallow subwoofer
- power range: 100-300 watts RMS (1,200 watts peak power)
- mounting depth: 3-1/8"
