Product details
A-Series 6.5-inch 3-way coaxials
Pioneer voices the TS-A1671F for open, balanced daily listening in doors and rear decks. Continuous handling is 70 W RMS with 320 W peak headroom on a 4-ohm load. Sensitivity is 91 dB at 1 W/1 m, so modest head-unit power still moves air without an external amp.
Carbon-mica IMPP cone and PET dome stack
The 6.5-inch woofer uses carbon and mica reinforced Injection Molded Polypropylene for stiffness without excess mass. Above it sit a 1.63-inch cellulose-fiber midrange and an 11 mm (0.43-inch) PET hard-dome tweeter on a chrome-accented bridge, extending response from 37 Hz to 31 kHz.
Fitment and install basics
Mounting depth is 2-3/8 inches (59 mm) with a 5-5/8-inch cutout. Pioneer includes Multi-Fit adapters and speaker grilles so the pair drops into many OE openings. Match amplifier or head-unit power to the 70 W RMS rating and confirm door clearance before cutting panels.
