ASIN: B07QHXDSD4Model: REF3032CFXCategory: Car Coaxial Speakers

Overview

A pair of 3-1/2 inch two-way coaxial car speakers from Infinity's Reference line, built with edge-driven textile tweeters and a Plus One woofer cone for a compact factory-size upgrade.

This is the smallest coaxial size in the Reference lineup, and Infinity's own materials reserve the adjustable tweeter output control for the larger Reference coaxial and component models, not this one. Worth knowing going in so expectations match what this specific speaker actually offers.

  • 3-1/2 inch (87mm) two-way coaxial design
  • 25W RMS, 75W peak power handling
  • 91dB sensitivity, 85Hz-21kHz response
  • 3.0 ohm impedance

Who it's for

Drivers replacing small 3.5 inch factory speaker openings who want a sound upgrade without relocating speakers. Not for anyone expecting the adjustable tweeter control Infinity offers on its larger Reference speakers.

Pros and cons

Pros
  • Compact 3-1/2 inch coaxial size fits many factory locations
  • Edge-driven textile tweeter aimed at a non-harsh high end
  • Plus One cone geometry adds cone area over standard designs
  • Priced within Infinity's affordable Reference tier
Cons
  • No adjustable tweeter level control at this size, unlike larger Reference models

Performance notes

Rated at 25W RMS with 75W peak handling into a 3.0 ohm load, with 91dB sensitivity and an 85Hz-21kHz frequency response. The edge-driven textile tweeter is tuned to stay smooth rather than harsh at higher volume, and the Plus One cone geometry adds usable cone area within the same frame to help low-frequency output.
