Buying Guide: How to Find the Best 3.5 Inch Speakers
It is important to keep a few key factors in mind when searching for the perfect 3.5 speakers for your car so that you don’t settle for anything less than the best. Most of these features are common to most aftermarket speakers which is why it is important to do some research before purchasing any speaker. They include;
1. Speaker Sensitivity
This is the measure of how loud a speaker is depending on the power provided and it is measured in decibels (dB). If your car audio system is low-powered then you need a set of 3.5 speakers with high sensitivity of about 90dB and above. At the same time, if you have a high-powered audio system, a set of speakers with low sensitivity ratings will serve you well.
2. Power-Handling
Next, you need to consider the power handling of the speaker so that you able to know the amount of power (watts) that the speaker can handle. If your stereo system features a powerful external amp then you need 3.5 speakers with power handling that is close to the amp output. In short, you need to consider the maximum RMS and peak power handling alike so that to avoid sound distortion in the case of too much power or a scenario where the speakers struggle to deliver due to too little wattage.
3. 2-way or 3-way
Most 3.5 speakers are either 2-way speakers or 3-ways speakers. 2-ways speakers are also referred to as coaxial speakers are the most common units and they consist of a standard woofer and a tweeter. 3-way speakers, on the other hand, feature the above components and in addition, they feature the mid and high-frequency range enabling them to produce both the highs and lows resulting in much fuller and richer sound.
4. Speaker Compatibility and Configuration
Although the speakers are meant to enhance your driving experience, it is important that you select a set of speakers that match the value of your car. It is important that you gather enough information on the speakers available in the market with regard to the specifications and present them to the after-market speaker dealer. This will enable them to provide you with speakers with the right configurations for your ride.
5. The Build Materials
The materials used on various speakers’ components have a big impact on both the sound quality and general life span of the speakers. The major components feature popular materials such as silk, polypropylene, and textile brands that result in the production of warmer sound. Harder materials such as graphite, ceramics, or metal are also common and they lead to the production of fuller sound with higher tones.
The speaker surround components should be made of materials that are capable of withstanding heat and humidity. The casing around the woofer should preferably be made of rubber as it is more effective and long-lasting. Some woofers may feature foam or cloth surround which is still effective and less expensive.
Best 3.5 Inch car speakers FAQs
Q. How does a 3.5-inch speaker improve car audio?
Answer: 3.5-inch speakers improve the stereo imaging and vocal clarity of your auto sound system. An aftermarket 3.5” speaker will enhance the stereo effect of audio signals. A set of well-chosen 3.5s also improves bass output, and allows your audio system to produce very smooth music at all output levels. Unlike stock speakers, new 3.5” speakers will eliminate any harshness in the sound, thus making the overall audio more enjoyable.
Q. Which type of 3.5-inch speakers is best for my car audio system?
Answer: 3.5 car speakers are widely classified as coaxial/full-range and component. Full range 3.5s are a simpler and cheaper upgrade for OEM speakers. A 2-way coaxial speaker set-up includes a woofer and a tweeter in one woofer cone. A 3-way configuration (more advanced set-up) is popular among many car audio enthusiasts. This configuration comprises mid-range speakers.
Component 3.5s consist of separate components in one sound system. You may choose a speaker designed with an independent tweeter connected to a subwoofer cone. Also, component 3.5s with separate mid-range speakers are available. The separation of sound components improves the speaker’s frequency response. Therefore, component 3.5 car speakers tend to sound better than coaxials. However, it’s important to note that installing component 3.5-inch speakers is more time-consuming compared to coaxials.
Q. Are 3.5-inch speakers good car door speakers?
Answer: If you are looking for mid-sized speakers to install on your car doors, consider the dimensions of the speaker carefully. While some 3.5s can make great options for car doors, some have large magnets that make the speaker too deep to fit in car doors. You need to ensure that the speaker you choose will allow the windows to roll down fully after installation.
No matter how great a set of speakers is, if it can’t fit your desired locations in the car, then it is almost unsuitable or useless. Some installation experts can cut the door card to make a speaker fit in. Should you choose to go this way, make sure that the professional has experience with such adjustments; otherwise, the installation might be closed at a horrible end.
Q. Will the new 3.5-inch speaker fit in the spaces factory speakers leave?
Answer: To avoid the possible stresses and disappointments of hectic car speaker installations, make sure that the speakers you choose are compatible with the model of your car. You can check online if a specific speaker is suitable for your vehicle. An even more assuring way is measuring the dimensions of your factory speakers and comparing them with those of the new speaker you want to buy. If the sizes match, this means you will not have to make any modification to the original mounting hole when installing the new 3-5 speaker.
Q. Will I need an amplifier for my newly installed 3.5-inch car speakers?
Answer: Most 3.5-inch speakers can work with an aftermarket head unit or a low-powered factory stereo. That said, however, many people choose to use aftermarket speakers with an amplifier. The most significant advantage of having an amplifier is that you get a much stronger sound. The presence of an amplifier also reduces the chances of sound distortion, besides preventing blown-out speakers or head units.
If you already have an amplifier, make sure that the power rating of the 3.5 speakers you want to choose matches the power rating of the amp.
Q. Which is the best 3.5-inch car speaker for sound quality?
Answer: You want to invest in a speaker that will improve the sound quality of your car audio system. Among the wide variety of available speakers, consider 3.5–inch speakers that have a large cone area for increased sensitivity and better low-frequency output. Also, speakers with woofers that are made of sturdy polypropylene and rubber materials shine when it comes to sound performance. Don’t forget to check 3.5 speakers with high-quality tweeters as these add incredible clarity to the sound.
Q. Are 3.5-inch speakers expensive?
Answer: 3.5-inch car speakers are among the cheapest components of a highly customized car audio system. You can find great 3.5s under $30. Take your time to search for the best speakers for your system, and you will take home one that suits your budget.
