Easily Upgrade to High Performance

Pioneer’s A-series shallow-mount subwoofers delivers big bass performance of a full-size subwoofer, but in a compact design. Designed to provide wider installation options for a broad range of vehicle, this A-Series subwoofer produces seamless and smooth sound characteristics with dynamic, high impact bass that lets you hear and feel the music.

Subwoofer Firing Options

This subwoofer features a full grille and down-firing structure for cone protection and can be installed inside your vehicle's interior. This combines deep, powerful bass while seamlessly integrating physically, electrically, and more importantly improves the acoustics in the vehicle.

This subwoofer was designed with the flexibility to be installed in three different ways. The provided feet can be screwed onto the bottom or top using the pre-drilled holes. Cushions on the feet prevent sliding.

Down-fire –With the four feet installed to the bottom of the subwoofer to allow space between the cone and the floor, it will push the soundwaves towards the floor where they are reflected to deliver a richer sound for a stronger “rumble” effect.

Up-fire –This option allows you to place the subwoofer with the cone facing upward. It can use the provided feet to prevent sliding. Firing the sub upwards moves more cabin air to deliver a stronger, more crisp sounding bass.

Vertical-Facing – This option allows you to place the subwoofer with the cone facing on its side. It can use the provided feet to prevent sliding. This position will disperse sound like conventional loudspeakers producing fast and impactful bass, hitting the ear before being reflected off a surface which can lead to an especially precise and punchy sound.

Angled Subwoofer 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 angled binding-post terminals make it easy to connect speaker wires, saves space, and makes installation easier. Two metal angle-brackets and eight 1" screws are provided for mounting the enclosure to a trunk or rear compartment floor in an upright fashion. Four screw-on feet also allow the enclosure to be mounted flat under a seat in a down-firing configuration.

Bass Driver

The TS-A2500LB features a single 10” driver made with a glass fiber and a mica interlaced, injection molded polypropylene (IMPP™) cone with butyl rubber surround, mounted in a matched sealed enclosure. The subwoofer’s voice coil suspension system is engineered to give balanced and linear motion of the cone, maintaining a high level of performance, response, and linearity, for superior sound.
