Frequency Response
They sound better than other 4" speakers I've tried, but not great for bass. Really can't expect too much out of a 4" though, so decent and worth a try.
Build Quality and Materials
For the money, these speakers seemed like a $10,000 upgrade for my $120k excavator. Clean, crisp, and a little boom boom bass made these speakers worth every last penny.

Buying Guide for the Best 4 Inch Car Speakers

Choosing the right 4-inch car speakers can significantly enhance your in-car audio experience. When selecting car speakers, it's important to consider various specifications that will affect the sound quality, compatibility with your car, and overall performance. Understanding these key specs will help you make an informed decision and ensure that you get the best fit for your needs.
Power HandlingPower handling refers to the amount of power a speaker can handle without getting damaged. It is usually measured in watts and is divided into two values: RMS (continuous power) and Peak (maximum power). RMS is more important as it indicates the power level the speaker can handle on a continuous basis. If you have a powerful amplifier, look for speakers with higher RMS ratings to ensure they can handle the power output. For standard car audio systems, lower RMS ratings may suffice.
SensitivitySensitivity measures how effectively a speaker converts power into sound, indicated in decibels (dB). Higher sensitivity speakers produce more sound from the same amount of power compared to lower sensitivity speakers. If you have a low-powered car stereo, look for speakers with higher sensitivity (above 90 dB) to get better sound output. For high-powered systems, sensitivity is less critical but still important for overall efficiency.
Frequency ResponseFrequency response indicates the range of frequencies a speaker can reproduce, measured in Hertz (Hz). A wider frequency range means the speaker can produce both low bass and high treble sounds. For a balanced sound experience, look for speakers with a frequency response that covers at least 60 Hz to 20,000 Hz. If you enjoy deep bass, consider speakers with a lower minimum frequency.
ImpedanceImpedance is the electrical resistance of the speaker, measured in ohms. Most car speakers have an impedance of 4 ohms, which is compatible with most car audio systems. Lower impedance (e.g., 2 ohms) can draw more power from the amplifier, potentially providing louder sound, but ensure your amplifier can handle it. Higher impedance (e.g., 8 ohms) is less common in car speakers and may require a more powerful amplifier.
Build Quality and MaterialsThe build quality and materials of the speaker components, such as the cone, surround, and tweeter, affect durability and sound quality. Cones made from materials like polypropylene or woven fabrics are durable and provide good sound reproduction. Rubber surrounds are more durable than foam surrounds. Tweeters made from materials like silk or metal can affect the clarity and brightness of the high frequencies. Choose materials that match your sound preference and durability needs.
Speaker ConfigurationSpeaker configuration refers to the design and number of drivers in the speaker. Coaxial (or full-range) speakers combine multiple drivers (woofer and tweeter) in one unit, making them easier to install and suitable for general use. Component speakers separate the drivers, allowing for better sound quality and customization but requiring more complex installation. Choose coaxial speakers for simplicity and component speakers for higher sound quality and customization.
