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 3-1/4".
The TS-A2500LS4 features an oversized, glass fiber and mica reinforced 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.

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"

I just built a very small sealed enclosure for this sub to fit into under seat storage bin of my Ford Maverick truck. Total volume of sealed enclosure is .65 cu. ft which comes out to .37 of useful volume. It sounds great and I am very pleased.
