Our take on the Infinity Reference Series 6-1/2" Speakers

When you listen to Infinity's 612i 6-1/2" speakers, it's clear that they were made by a company that's been making speakers for over a quarter of a century. You won't get the overly bright, boomy sound of lesser car speakers — you'll hear accurate and detailed reproduction of the music the way it was recorded.

The TLH (poly/paper laminated) woofer, a silk semi-dome tweeter, a rubber surround, and a little bit of Infinity know-how join together to produce a speaker that will make your tunes come alive!
