Buying Guide For The Best 8 Inch Subwoofer
1. Power Rating
Why It Matters: The power rating of a subwoofer, measured in watts, indicates how much electrical power the subwoofer can handle and produce as sound. It’s divided into two main categories: RMS (Root Mean Square) and Peak Power. RMS power gives you an idea of the continuous power the subwoofer can handle without experiencing damage, while Peak Power indicates the maximum power it can handle in short bursts. A higher power rating often means the subwoofer can deliver louder and more dynamic bass.
What to Look For: Look for a subwoofer with a power rating that matches or exceeds the output of your amplifier or receiver. Pay more attention to the RMS power rating than the Peak Power, as it’s a more realistic measure of the subwoofer’s performance. An 8-inch subwoofer with an RMS rating of 100-300 watts is generally sufficient for most home and car audio systems.
2. Frequency Response
Why It Matters: Frequency response measures the range of sound frequencies the subwoofer can reproduce, typically given in Hz (hertz). It indicates how low and how high the subwoofer can play. For subwoofers, the lower end of the frequency response is more relevant, as their primary role is to reproduce low-frequency sounds (bass). A wider frequency response range means the subwoofer can produce a fuller and more detailed bass.
What to Look For: Ideal 8-inch subwoofers should have a lower frequency limit of around 20-30Hz to ensure deep bass performance. The upper limit is less critical, as higher frequencies are handled by other speakers in a system. However, a subwoofer that can reach up to 200Hz might blend better with satellite speakers, creating a smoother transition between high and low frequencies.
3. Impedance
Why It Matters: Impedance, measured in ohms, represents the electrical resistance of the subwoofer’s voice coil to the power supplied by the amplifier. It plays a critical role in the compatibility between the subwoofer and the amplifier. Most subwoofers are rated at 4 ohms, but 2-ohm and 8-ohm models are also common. Matching the subwoofer’s impedance with the amplifier ensures efficient power usage and optimal performance.
What to Look For: It’s essential to choose a subwoofer whose impedance matches that of your amplifier to avoid any strain or damage. If your amplifier is designed to drive a 4-ohm load, select a subwoofer with the same impedance rating. Some subwoofers offer multiple voice coils (dual voice coil, for example), providing more flexibility in wiring and making it easier to match the amplifier’s impedance requirements.
4. Voice Coil
Why It Matters: The voice coil is the component within the subwoofer that interacts with the magnetic field to produce sound. Its design, including size and type, significantly affects the subwoofer’s power handling, cooling capabilities, and durability. Voice coils can be single or dual, with dual voice coil (DVC) subwoofers offering more wiring flexibility, which can be advantageous for optimizing your system’s impedance.
What to Look For: Consider the voice coil’s diameter and winding material. A larger diameter (e.g., 2 inches or more) generally means better power handling and heat dissipation. Copper is a common winding material, but aluminum or copper-clad aluminum can offer superior cooling. For those seeking flexible wiring options, a DVC subwoofer might be the best choice.
5. Sensitivity
Why It Matters: Sensitivity, measured in decibels (dB), indicates the efficiency with which a subwoofer converts power into sound. A higher sensitivity rating means the subwoofer can produce more sound (volume) from the same amount of amplifier power. This can be particularly important in setups where the amplifier power is limited, as a more sensitive subwoofer will deliver louder bass without requiring a high-powered amp.
What to Look For: Look for a subwoofer with a sensitivity rating of at least 85dB. However, subwoofers with ratings of 90dB or higher are considered highly efficient and can make the most of your amplifier’s power. Remember, a difference of 3dB in sensitivity can effectively double the perceived volume from the same power input.
6. Cone Material
Why It Matters: The material of the subwoofer’s cone plays a crucial role in its sound quality and durability. It needs to be light enough to move quickly but rigid enough to avoid distortion under high power. The cone’s material can also affect the subwoofer’s overall sound character, with different materials imparting subtle nuances to the bass.
What to Look For: Look for materials that combine lightness and strength. Polypropylene is a popular choice for its mix of flexibility and durability. Composites or blends with materials like mica or aluminum can offer enhanced stiffness and water resistance, which is especially beneficial for car audio systems. For those prioritizing sound quality, consider woven fabrics or specialized materials like Kevlar, which provide excellent damping properties and reduce distortion.
8 Inch Subwoofer FAQS
Ans: Well, it depends on what type of music you listen to and more importantly, how big your car is. If you are talking about a standard commercial car, then an 8 inch subwoofer can easily offer a loud and strong output which is more than enough. However, it may not be sufficient for large cars. Also, the overall power capacity of the subwoofer depends upon many different factors such as its sensitivity, power output rating, and frequency response apart from the physical size.
Ans: When it comes to installation, an 8 inches subwoofer is probably the best option. Compared to many other popular options on the market, an 8 inches subwoofer is relatively easier to install since it only needs about .35 cubic feet of installation space. However, the necessary installation space may vary depending on the enclosure of the subwoofer you are buying.
Ans: Larger speakers certainly have the advantage of a powerful sound output capacity, or a stronger bass output since we are talking about subwoofers. So, a 10 inch subwoofer is certainly going to be more powerful than a 8 inch one. But, you also need to consider some other factors such as the power rating of the speaker. For example, you may find a 1200 Watt 8 inch subwoofer more enjoyable than a 600 Watt 10 inches model.
