Infinity Primus 683F 6"x8" / 5"/7" Coaxial Speakers

The Infinity Primus 683F is a 6"x8" 2-way coaxial speaker pair built for car audio enthusiasts who demand tighter bass, clearer vocals, and high-volume detail from a wide range of vehicles. A cooling vented basket frame helps maximize output with less wear over time.

• 6"x8" 2-way coaxial design: A single enclosure that integrates woofer and tweeter for broad, balanced sound in many vehicle install locations.
• Plus One+ polypropylene woofer cone with hi-roll rubber surround: More surface area than a typical cone provides punchier bass response and durable edge sealing for reliable performance.
• 1/2" edge-driven silk dome tweeter: Crisp high-frequency extension with smooth response and reduced distortion at higher listening levels.
• Edge-driven tweeter design: An open sound with minimal distortion at high volume, helping natural detail in vocals and cymbals.
• 3-ohm impedance: Compatible with virtually all factory or aftermarket car stereos, allowing efficient power draw for louder playback from your head unit or amp.
• True 4-ohm architecture: Infinity’s approach uses a low-impedance voice coil to safely draw extra power from your system for stronger, clearer output.
• Power handling: Handles up to 50 watts RMS (150 watts peak power), providing a practical range for common head units and small amplifiers without risking distortion.
• Frequency response: 65–20,000 Hz, covering vocal fundamentals through bright cymbals for a full-range sound.
• Sensitivity: 92 dB at 2.83 volts, indicating efficient loudness with modest input power.
• Cooling vented basket frame: Designed to sustain high-output performance and reduce thermal wear during extended listening sessions.
• What’s in the box: Infinity Primus 683F owner's manual; two 2-way speakers; two 9" lengths of speaker wire (each with female quick-slides on one end and tinned wire on the other); eight 1" screws; eight speed clips; two adhesive-backed foam gaskets; template and specs on box.
• Warranty: 1 year.

Benefits: This pair is ideal for upgrading factory speakers where space allows a 6"x8" fit. The Plus One+ cone and edge-driven tweeter deliver punchy bass with detailed highs, while the 3-ohm impedance and true 4-ohm architecture optimize power delivery from a wide range of stereos. The cooling vented basket frame supports sustained output, making these Primus speakers a solid choice for everyday listening and spirited system builds alike.
