It looked like someone opened it, saw that it would not fit their car, and returned it. I installed it anyways, as it was the last one in stock, and so far, there are no issues. highs sound clean, crisp. i had to EQ the treble lower, as it was too much treble, espexially with the other infinity reference speakers i installed (two 6.5 inch and two 6x9") I paid around 80$ canadian (much cheaper than anywhere else), so cant really complain about the open box Review: Calidad alta - Es de lo mejor del mercado, si se siente la diferencia en tu auto, si le da una mejor calidad al audio, en realidad notas muchísimo la claridad, un tono algo prime, quede encantado ## Features - 135W Max - 45W RMS Out Put - 3.0 ohms Impedance ## Technical Specifications | Specification | Value | |---------------|-------| | ASIN | B01E8OYLH6 | | Antenna Location | Car | | Audio Driver Type | Dynamic Driver | | Audio Output Mode | Stereo | | Audio output mode | Stereo | | Best Sellers Rank | #109,175 in Electronics ( See Top 100 in Electronics ) #398 in Coaxial Car Speakers | | Brand | Infinity | | Built-In Media | A Pair Of Tweeters And Standard Accessories | | Color | BLACK | | Compatible Devices | vehicle | | Connectivity Protocol | Wi-Fi | | Connectivity Technology | Auxiliary | | Connectivity technology | Auxiliary | | Control Method | Touch | | Customer Reviews | 4.5 out of 5 stars 105 Reviews | | Enclosure Material | Textile, Aluminum, Plastic/Metal | | Frequency Response | 29000 Hz | | Frequency response | 29000 Hz | | Global Trade Identification Number | 00050667371036 | | Impedance | 3 Ohms | | Is Waterproof | False | | Manufacturer | Answer Infinity | | Maximum Range | 10 Meters | | Model Name | REF-275tx | | Model Number | REF-275tx | | Mounting Type | Flush Mount | | Mounting type | Flush Mount | | Number of Audio Channels | 2.0 | | Number of Items | 1 | | Power Source | Corded Electric | | Speaker Maximum Output Power | 75 Watts | | Speaker Size | 3.5 Inches | | Speaker Type | Tweeter | | Speaker maximum output power | 75 Watts | | Specific Uses For Product | in-car audio systems | | Subwoofer Diameter | 6.5 Inches | | Tweeter Diameter | 0.75 Inches | | UPC | 050667371036 | | Unit Count | 1 Count | | Wireless Technology | Wi-Fi | ## Product Details - **Audio output mode:** Stereo - **Brand:** Infinity - **Connectivity technology:** Auxiliary - **Frequency response:** 29000 Hz - **Speaker maximum output power:** 75 Watts ## Images ![REF3022CFX 3.5" 75W Reference Series Coaxial Car Speakers With Edge-driven Textile Tweeter, Pair REF-275tx - Image 1](https://m.media-amazon.com/images/I/7126T8PRcJL.jpg) ## Available Options This product comes in different **Style** options. ## Questions & Answers **Q: Do they come in pairs?** A: Yes they do come as a pair.

They sound great, easy to install if you have the setup in your car already. I've had Infinity speakers in my house since 1998 and to this day they still perform great. So I don't see why the car version wouldn't as well. Great speakers for the price. ## Frequently Bought Together - Infinity REF-275tx 135W Reference Series Edge-Driven Textile Car Tweeters, 3/4" - Infinity Reference REF-9633IX 6x9 3-Way Coaxial Speakers (300 WATTS 100 RMS) --- ## Why Shop on Desertcart? - 🛒 **Trusted by 1.3+ Million Shoppers** — Serving international shoppers since 2016 - 🌍 **Shop Globally** — Access 737+ million products across 21 categories - 💰 **No Hidden Fees** — All customs, duties, and taxes included in the price - 🔄 **15-Day Free Returns** — Hassle-free returns (30 days for PRO members) - 🔒 **Secure Payments** — Trusted payment options with buyer protection - ⭐ **TrustPilot Rated 4.5/5** — Based on 8,000+ happy customer reviews **Shop now:** [https://www.desertcart.jp/products/304140072-ref3022cfx-3-5-75w-reference-series-coaxial-car-speakers-edge](https://www.desertcart.jp/products/304140072-ref3022cfx-3-5-75w-reference-series-coaxial-car-speakers-edge) --- *Product available on Desertcart Japan* *Store origin: JP* *Last updated: 2026-07-16*
