Their compact design ensures compatibility with virtually any vehicle, making them the perfect upgrade for music lovers on the go. ## 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: Value for money - These took an $11.00 wiring harness adapter and maybe 15 minutes to install. The fit is perfect. It helped transform the truly awful stock speaker system in my Toyota Rav4 into something very enjoyable (I also upgraded the door speakers). Highs and mid-range are crisp and clear. I do not find them overly bright. Although I could find no information on the sensitivity of the stock speakers in the Rav4, at 91 dB, the Infinity Ref307F appears to be more sensitive, too. There was a definite and welcome boost in volume. ## Features - The audiophile-grade tweeters used in Infinity's new Reference speakers deliver smooth, non-fatiguing sound even at high output levels. - The larger Reference multielement and component systems offer a tweeter output level control to optimize system linearity to suit installation location or the listener's preference. - Harman’s patented (US patent #7,548,631) Plus One cones provide more overall speaker-cone area than other cones in its class - the result is higher sensitivity, increased low-frequency output and accurate music reproduction. - Reference speakers are available in a range of standard sizes, and feature a compact design that allows them to fit just about any vehicle on the road today. ## Technical Specifications | Specification | Value | |---------------|-------| | ASIN | B0CV4HFR9Z | | Additional Features | Lightweight | | Antenna Location | For Surround Sound Systems | | Audio Driver Type | Dynamic Driver | | Audio Output Mode | Stereo | | Best Sellers Rank | #22,936 in Electronics ( See Top 100 in Electronics ) #172 in Car Coaxial Speakers | | Brand | Infinity | | Built-In Media | REF307F | | Color | black | | Compatible Devices | Desktop, Laptop, MP3 Player, Projector, Smartphone, Tablet, Television | | Compatible with Vehicle Type | & SUVs, Select Cars, Truck | | Connectivity Protocol | Coaxial | | Connectivity Technology | Coaxial | | Control Method | Touch | | Customer Package Type | FFP | | Customer Reviews | 4.7 out of 5 stars 84 Reviews | | Enclosure Material | Plastic | | Is Waterproof | FALSE | | Item Dimensions D x W x H | 8.46"D x 2.95"W x 5.35"H | | Item Weight | 1.8 Pounds | | MP3 player | No | | Manufacturer | Infinity | | Material | Plastic | | Model Name | REF307F | | Model Number | JBLSENSELITEBLKAM | | Mounting Type | Flush Mount | | Number of Audio Channels | 2.0 | | Number of Items | 1 | | Power Source | Corded Electric | | Speaker Maximum Output Power | 50 Watts | | Speaker Size | 3.5 Inches | | Speaker Type | Coaxial | | Specific Uses For Product | Car audio systems and home surround sound systems | | Subwoofer Connectivity Technology | Wired | | Tweeter Diameter | 3.5 Inches | | UPC | 050667379957 | | Unit Count | 1.0 Count | | Warranty Description | 1-Year Manufacturer Warranty | | Warranty Type | Limited | | Woofer Diameter | 8.89 Centimeters | ## Product Details - **Brand:** Infinity - **Speaker Maximum Output Power:** 50 Watts - **Connectivity Technology:** Coaxial - **Audio Output Mode:** Stereo - **Mounting Type:** Flush Mount ## Images ![REF307F 3.5 Inch 2 Way Car Speakers - Pair - Image 1](https://m.media-amazon.com/images/I/61lfOOqLRVL.jpg) ![REF307F 3.5 Inch 2 Way Car Speakers - Pair - Image 2](https://m.media-amazon.com/images/I/61Wbv0Ehi+L.jpg) ![REF307F 3.5 Inch 2 Way Car Speakers - Pair - Image 3](https://m.media-amazon.com/images/I/61gXWdFTQzL.jpg) ![REF307F 3.5 Inch 2 Way Car Speakers - Pair - Image 4](https://m.media-amazon.com/images/I/71rIOb3JvwL.jpg) ![REF307F 3.5 Inch 2 Way Car Speakers - Pair - Image 5](https://m.media-amazon.com/images/I/51gnphTBGnL.jpg) ## Customer Reviews ### ⭐⭐⭐⭐⭐ Excellent upgrade over Ram 1500 OEM dash speakers. *by S***P on March 8, 2026* 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.
