## 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. Available in a range of standard sizes - 3-1/2", 4", 5-1/4", 6-1/2", 6" x 8" and 4" x 6" coaxial, 6" x 9" 3-way, and 5-1/4", 6-1/2", and 6" x 9" component - they’re the perfect upgrade from factory speakers.

Review: Excellent upgrade over Ram 1500 OEM dash speakers. - Excellent replacement for Ram 1500 (DT series) OEM dash speakers - substantial detail clarity increase over cheap factory speakers and simple 15-minute install with the correct Metra 72-7902 harness adapters. No-brainer upgrade whether by themselves or in tandem with complementing Infinity Reference door speakers for a total plug & play interior audio performance improvement. Note on the 'Alpine' system, these arguably sound even better when you remove the center dash speaker.
Review: Nice sound upgrade - Very easy to install. Sounds awesome. Great price

### ⭐⭐⭐⭐⭐ I love Infinity. Perfect.
*by B***Y on July 4, 2026*

Infinity makes amazing car audio products, I’ve been using them for more than 20 years. You can never go wrong with any of their products. The design is clean and unobtrusive, they will match well with any vehicle trim. The sound is crisp and clear, perfect audio quality for high frequencies. For the quality these are far cheaper than their competitors.
