Pioneer TS-G1320S 5.25" 2-Way Coaxial Speakers

The Pioneer TS-G1320S is a pair of 5.25-inch coaxial car speakers designed to replace worn or limited factory speakers in compatible vehicle locations. Its 2-way layout combines a woofer and tweeter in each speaker, helping cover bass, vocal, and treble duties from one compact mounting position. It is a practical option for drivers seeking a straightforward OEM-style speaker replacement with clear everyday sound.

With 35 watts nominal power handling and a 4-ohm impedance, the TS-G1320S is suited to many conventional car-audio speaker circuits. Its 88 dB sensitivity helps it produce useful output from modest power, including compatible factory or aftermarket head-unit amplification. A 250-watt maximum music-power rating provides additional short-term power-handling headroom.

The 5.25-inch woofer uses Pioneer’s mica-reinforced Injected Molded Polypropylene (IMPP) cone. This lightweight, rigid cone construction is intended to support responsive midrange and bass reproduction while helping control distortion. A Conex damper and Pioneer P.F.S.S. spider support cone movement during playback.

For upper frequencies, each speaker uses a 30 mm PET hard-dome balanced tweeter. The coaxial arrangement places the tweeter in the center of the woofer, allowing both drivers to install through one speaker opening. The specified 33 Hz to 24 kHz frequency response provides broad coverage for full-range music playback.

The TS-G1320S is designed with a shallow 1.75-inch mounting depth for use in a wide range of vehicle speaker locations. It requires a 4.75-inch cutout, so vehicle-specific fitment and clearance behind the mounting surface should be checked before purchase. It can serve as a direct factory-speaker replacement or as part of a basic system upgrade paired with a compatible 4-ohm source or amplifier.

Key Features

• Coaxial 2-Way Design: Integrates woofer and tweeter in each speaker for full-range sound from one mounting location.
• 35W Nominal Power: Matches modest-power factory and aftermarket audio systems.
• 250W Maximum Music Power: Provides short-term power-handling capacity for dynamic listening.
• Mica-Reinforced IMPP Cone: Uses a lightweight, rigid woofer cone designed to help reduce distortion.
• 30 mm PET Dome Tweeter: Reproduces high-frequency detail from a centered coaxial tweeter.
• P.F.S.S. Spider: Supports controlled cone movement for more linear sound reproduction.

Design & Installation

The TS-G1320S uses a mica-reinforced IMPP woofer cone, PET hard-dome tweeter, Conex damper, and Pioneer Progressive Flex Suspension System spider. Its 129 mm woofer frame and 110 g magnet are built into a compact coaxial assembly. The speaker’s balanced-dome tweeter is centrally mounted to keep the design compact.

Confirm that the vehicle has a compatible 5.25-inch speaker position, a 4.75-inch cutout, and at least 1.75 inches of mounting depth. Use the supplied mounting hardware as applicable, maintain correct speaker polarity, and prevent the speaker leads or terminals from touching vehicle metal. For amplified systems, use a compatible 4-ohm channel and avoid distortion or sustained operation beyond the speaker’s nominal power rating.
