Infinity REF467F

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. Available in a range of standard sizes, they’re the perfect upgrade from factory speakers.

Mind-Blowing Bass & Clarity - The Ultimate Factory Upgrade for the 2015 Camry!

The following review is for REF697F, which is a part of the bundle you are viewing.

I recently purchased and installed the Infinity Reference 697f speakers in the rear deck of my 2015 Toyota Camry, and I am absolutely blown away. The build quality is top-notch, featuring solid construction, a decent tweeter, and bass that is honestly "damn good"—far exceeding my expectations for a non-amplified setup.
Every song comes through with crystal-clear vocals and rich, distinct sound. If you are looking for the perfect drop-in speaker upgrade to run directly off the factory Toyota radio, look no further. These are worth every penny! I really liked it nothing cons about it.

The following review is for REF697F, which is a part of the bundle you are viewing.

These speaker are a very good fit for the front doors. I no problems installing them and the pigtails made it easier yet. They also have a good sound. Especially compared to the stock ones that buzzed.
