Can coaxial speakers be used for front doors?
2 Answers
Front doors can be equipped with coaxial speakers, which are cost-effective and suitable for those looking to upgrade their car audio system for the first time. Here is some relevant information: Definition of coaxial speakers: Coaxial speakers are designed to handle both high and low frequencies. They feature two speakers mounted on the same axis, one responsible for reproducing high frequencies and the other for mid-low frequencies. Additionally, the diaphragms of these two speakers overlap, and because their physical positioning is close to a single point, they effectively address phase deviation issues. Characteristics of coaxial speakers: The standout feature of coaxial speakers is their high phase fidelity across the full audio spectrum, from high to low frequencies. This improved phase fidelity results in clear and accurate sound positioning and movement, making it easier to distinguish the positions of various instruments in music, thus delivering transparent and crisp audio. Such speakers are particularly well-suited for reproducing the sound effects of AC-3 standard home theater systems in DVDs and Hi-Fi playback, and they are even more suitable for use in confined spaces.
When I was doing car audio modifications before, I noticed many people install coaxial speakers in the front doors because they suit doors with limited space. Coaxial speakers stack the tweeter and mid-bass units together, saving space and making installation easier. The most common size on the market is the 6.5-inch model. Check if the door hole size matches the speaker—if it's slightly larger, you'll need to add a spacer ring to prevent sound leakage. When wiring, pay attention to the polarity (positive/negative) to avoid reverse connection, and ensure the power matches the car's original amplifier—too high power may blow the fuse. I once replaced a pair in a Toyota, and the sound became much clearer, especially the vocals, though the bass was slightly lacking. If the door soundproofing isn't done well, adding a layer of soundproofing foam can make the sound more balanced. It's recommended to go to a professional shop—they can get it done quickly without damaging the interior. The cost is usually around 500 RMB, and entry-level brands like JBL or Sony are sufficient. Before modification, test the car's voltage to ensure stability.
