Pioneer TS-A4671F 4" x 6" 4-Way Coaxial Speakers

The Pioneer TS-A4671F is a pair of 4" x 6" four-way coaxial car speakers designed to replace compatible factory speakers. It provides a practical upgrade path for vehicles whose original speakers sound worn, limited, or unclear. Its 4-ohm design works with many factory and aftermarket car stereos, subject to vehicle fitment and wiring compatibility.

Each speaker combines a 4" x 6" woofer, 42 mm midrange, 11 mm tweeter, and 11 mm super tweeter in one coaxial assembly. This multi-driver layout is intended to distribute low, middle, and high frequency reproduction among dedicated drivers. The result is a broad stated frequency response from 34 Hz to 49 kHz.

The TS-A4671F is rated for 30 watts RMS and up to 210 watts maximum power handling. Its 88 dB sensitivity rating supports use with modest-power factory radios while leaving room for a properly matched external amplifier. The nominal 4-ohm impedance is a common match for car-audio speaker outputs.

Pioneer uses a carbon- and mica-reinforced injection-molded polypropylene woofer cone to balance low mass with rigidity. A cellulose-fiber cone serves the midrange, while PET hard-dome drivers handle the tweeter and super-tweeter duties. The A-Series Open & Smooth concept is designed to support a more consistent off-axis response in vehicle interiors.

These speakers are suited to a stock-location replacement where a 4" x 6" opening is available and mounting clearance has been verified. They can be used with a factory head unit or as part of a larger system that adds an amplifier and compatible source unit. Confirm the cutout, mounting depth, terminal clearance, and vehicle-specific mounting pattern before installation.

Key Features

• Four-Way Coaxial Layout: Integrates woofer, midrange, tweeter, and super tweeter drivers in each speaker.
• 30W RMS Handling: Supports everyday use with factory radios or matched amplification.
• 210W Maximum Power: Provides short-term peak power handling capability.
• Carbon/Mica IMPP Woofer: Uses a reinforced polypropylene cone for controlled cone movement.
• Open & Smooth Design: Supports more consistent off-axis response in vehicle interiors.
• 4-Ohm Impedance: Matches the common impedance used by many car audio systems.

Design & Installation

The TS-A4671F uses an iron-plate pressed basket, a carbon- and mica-reinforced IMPP woofer cone, a cellulose-fiber midrange diaphragm, and PET hard-dome high-frequency drivers. Its woofer uses a ferrite magnet, while the tweeter assembly uses neodymium magnet material. Additional construction details include an aramid-fiber damper, rolled rubber-coated cloth surround, glass-imide voice-coil bobbin, and copper-clad aluminum voice-coil wire.

Verify that the vehicle accepts a 4" x 6" speaker with a 95 x 153 mm cutout and 42 mm mounting depth. Connect the speakers to compatible 4-ohm speaker outputs and ensure the leads and terminals cannot contact metal. The package includes mounting-related accessories, but vehicle-specific adapters or wiring harnesses may still be needed depending on the application.
