EASILY UPGRADE TO HIGH PERFORMANCE

Pioneer’s A-series sound design purposely matches the subwoofer and full-range loudspeakers to provide seamless and smooth sound characteristics with dynamic, high impact bass that lets you hear and feel the music.

SHALLOW COMPACT DESIGN

Our shallow-mount subwoofer line, also known as slim subwoofers, is designed to provide greater installation options for a wide range of vehicles. These slim subwoofers feature many patent-pending innovations to deliver powerful bass performance typically associated with a full-size subwoofer, but in a more compact design that can be installed behind or under seats, depending on the vehicle type. The shallow mounting depth not only allows for the use of smaller, slimmer speaker boxes, but also enables this type of subwoofer to be installed in locations that were previously impossible.

GLASS-FIBER & MICA REINFORCED IMPP™

Polypropylene (PP) is a tough thermoplastic resin that is an ideal material for a speaker cone due to its low mass and high damping properties. PP cones offer good sensitivity and low distortion. However, basic raw polypropylene cones lack the rigidity and strength required for high output and extreme low bass. To resolve this, Pioneer engineers, using advanced Computer-Aided Manufacturing, developed a process to blend glass fibers and mica into the polypropylene resin during the injection molding process. The resulting reinforced IMPP™ cone is thinner and low mass with high rigidity and superior strength, producing natural, detailed sound with deep and powerful bass.

BUTYL RUBBER SUSPENSION

Made from a specially blended, highly durable, and moisture-resistant compound, the butyl rubber keeps the cone moving in a precise linear direction. Not only does it provide greater consistency across various excursions, but it also reduces unwanted vibration from the cone to the basket during signal changes and stops. This results in less distortion and superior bass frequency response.

DOUBLE ARAMID FIBER SPIDER

Pioneer's aramid fiber spider design effectively supports the voice coil by damping cone vibrations and improving linearity during sound reproduction. Its soft part ensures smooth movement and clear sound even under high power, while its firmer part controls excessive vibrations and prevents unwanted movements that cause distortion.

The design of a slim subwoofer requires a smaller distance between the front and rear suspensions, reducing their effectiveness in maintaining the necessary linearity during low-frequency excursions. To counter this disadvantage, Pioneer has developed a dual spider design, increasing the precision of movement without increasing mechanical resistance. The goal is simple: to provide all the details of your music by offering excellent control during long excursions while maintaining a small footprint in your car.

DEEP BASS

To achieve deep and tight bass, a rigid and lightweight cone is essential. However, without a proper motor structure, it’s ineffective if you’re looking for a good bass punch. The subwoofer uses a strontium magnet paired with a large copper voice coil and a glass-imide voice-coil former for better bass control under high excursions. This also helps achieve better heat dissipation.

CARSOUNDFIT APP

Pioneer's Car Sound Fit app is a car sound simulator that lets you experience what your car could sound like using your own smartphone. You'll be able to hear the difference between stock speakers and Pioneer's various audio options, and see how the quality of Pioneer speakers can enhance your in-car experience.
