## Description

New Reference speakers are designed to deliver Infinity’s signature sound in more vehicles. They feature edge-driven textile tweeters for smooth, clear highs and the larger models offer an adjustable tweeter output level control for high-frequency optimization based on installation location or the listener's preference. Oversized Plus One woofers offer more surface area for higher bass output and enhanced midrange performance. Plus our newly engineered baskets are optimized to fit most factory speaker locations. ---------------- Step up to a 1" edge-driven dome tweeter for smoother highs with minimal breakup. Plus, a supertweeter gives the high frequencies a bolder presence, and push-button tweeter attenuation lets you tweak any "brightness" you might hear. ----------------- The Reference Series polypropylene woofer with its durable hi-roll rubber surround ensures you'll enjoy powerful sound every mile you drive. Its oversized cone moves more air than other speakers of similar size, adding plenty of punch to the speaker's impressive performance. ----------------------- These speakers will really blossom when powered by an external amplifier, but they're also sensitive enough to be a good match for a factory or aftermarket stereo. Plus, Infinity comes up with a safe way to get a little more power out of your system — these 3-ohm speakers combine with the speaker wire in your car so your car stereo sees actual 4-ohm impedance.

Review: Excellent - but could not installed and hence to returrn - Excellent - but could not install due to shape (oval and not round) and hence to return. However, when tested the sound without installation, was an excellent quality including the build. Also delivery took more than a week - which is too long to wait.

### ⭐⭐⭐⭐⭐ Very efficient for low power input
*by A***R on 11 August 2024*

Have a factory 15W rms stereo in truck. Other (decent) 6x9 co-ax that were recommended replacements for my door speakers required a minimum 50W to drive them. These infinity speakers transfer the power very nicely, no distortion when volume way up. The efficiency of these speakers is very impressive. Just make sure of a few things before installing in door: 1) The speakers are deeper than the factory installs. Make sure you have enough room in the door speaker enclosure. I had to jerry-rig an included spacer/adaptor to offset them enough from door enclosure rim, to make them fit. I got lucky and it worked. 2) check the connector type between the door wiring and speaker connection points. I had to search for and found (on Amazon) the correct connector before I could install them. After all that fussing around, I was pleasantly satisfied with the sound.
