Pioneer TS-A6991FH 6x9" 5-Way Coaxial Speakers

The Pioneer TS-A6991FH is a pair of 6 x 9-inch, 5-way coaxial car speakers designed for vehicles that use this common oval speaker size. It provides an upgrade path for worn, damaged, or basic factory speakers while keeping the installation focused on a full-range coaxial design. Each speaker combines a woofer, midrange, tweeter, and two super tweeters in one assembly.

These speakers are intended for listeners who want broader frequency coverage from a factory-location replacement without adding separate component speakers. Their 4-ohm nominal impedance is suited to compatible automotive audio systems. Before purchase, verify both the vehicle's mounting opening and available depth.

The TS-A6991FH is rated for 150 watts RMS continuous power handling and 750 watts maximum music power. Its 93 dB sensitivity rating helps it produce useful output from a compatible car stereo or amplifier. For amplified systems, use an amplifier setup appropriate for the speaker's 4-ohm load and continuous-power rating.

Pioneer uses a carbon- and mica-reinforced IMPP cone for the 6 x 9-inch woofer, a material combination intended to support responsive bass reproduction. A 57 mm PEI cone midrange handles part of the vocal and mid-frequency range. The high-frequency section uses one 18 mm PET hard-dome tweeter plus 11 mm and 9 mm PET hard-dome super tweeters.

The coaxial 5-way layout keeps all drivers in a single speaker frame, making it practical for many rear-deck, door, or cargo-area speaker locations that accept 6 x 9-inch speakers. Pioneer lists a 29 Hz to 31 kHz frequency response and an 85.7 mm mounting depth. The pair can be used as a direct speaker replacement or as part of a larger system with a compatible receiver and amplifier.

Key Features

• 5-Way Coaxial System: Integrates five driver sections in each speaker for full-range playback from one mounting location.
• 150W RMS Handling: Supports up to 150 watts of continuous power handling for each listed speaker system specification.
• Carbon/Mica IMPP Woofer: Uses a reinforced 6 x 9-inch cone designed for responsive low-frequency reproduction.
• PEI Midrange Cone: The 57 mm midrange supports clear reproduction through the vocal range.
• Triple PET Dome Tweeters: An 18 mm tweeter and 11 mm and 9 mm super tweeters cover high-frequency detail.
• 4-Ohm Design: Matches the nominal impedance commonly used by compatible automotive speaker outputs and amplifiers.

Design & Installation

The TS-A6991FH uses a 6 x 9-inch carbon- and mica-reinforced IMPP woofer cone, a PEI midrange cone, and PET hard-dome high-frequency drivers. Its integrated coaxial construction places the midrange and high-frequency drivers over the woofer assembly. Pioneer also specifies an optimized symmetrical motor design with a large magnet.

Confirm that the vehicle accepts a 6 x 9-inch speaker, with a 6 x 8-3/4-inch cutout and at least 3-3/8 inches of mounting depth. Connect the speaker leads securely and ensure the terminals and leads cannot contact metal vehicle surfaces. The supplied documentation lists mounting hardware and speaker-wire leads; use vehicle-specific adapters or harnesses when required for a clean installation.
