Infinity REF687F

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.

I couldn’t hear my stock 3.5 speaker at all so I upgraded to the infinity and the sound is so pure and clear

The following review is for REF307F, which is a part of the bundle you are viewing.

Sound way clearer and better then the stock ones that were in my truck. Could see a big difference in weight too, and how much bigger the magnet was from the stock ones ????????

I had a faulty stock speaker in my Mustang Mach E and this replacement is just what the Dr ordered. Perfect fit and super easy install.
