Best 15 inch subwoofers – Buying Guide

When looking for 15-inch subwoofers, it’s crucial to measure the space where you’ll put them. Make sure to get the dimensions for both the speaker and the enclosure. Also, remember that if you choose a subwoofer with more than 1,000 watts RMS, you need to check if your car’s electrical system can handle it.

When you’re out shopping for a subwoofer, there are three main things to think about: power, sensitivity, and frequency response. These factors will determine how well the subwoofer performs and how loud it can get. So, pay attention to them while making your choice.

Power Handling: 

Power handling refers to the maximum amount of continuous power a 15-inch subwoofer can handle without getting damaged. It’s crucial to match the subwoofer’s power handling with the amplifier’s output power to avoid overloading or underutilizing the subwoofer’s capabilities.

RMS (Root Mean Square) Power: 

RMS power represents the continuous or average power that a subwoofer can handle. It is a more reliable measure of a subwoofer’s true power handling capabilities than peak power, as it indicates sustained performance without distortion or damage.

Peak Power: 

Peak power denotes the maximum power level a subwoofer can handle in short bursts. While it may be a useful marketing figure, it is less meaningful than RMS power when it comes to determining a subwoofer’s real-world performance and durability.

Frequency Response: 

The frequency response indicates the range of audio frequencies a subwoofer can reproduce, typically measured in Hertz (Hz). A wide frequency response ensures the subwoofer can produce deep, low-end bass, enhancing the overall audio experience.


Sensitivity measures how efficiently a subwoofer converts power into sound. Higher sensitivity values require less power to achieve the same volume level, making them a better match for lower-powered amplifiers.


Impedance is the electrical resistance that a subwoofer presents to the amplifier. Common impedance values for subwoofers are 2 ohms, 4 ohms, and 8 ohms. It’s essential to choose a subwoofer with an impedance that matches your amplifier’s capabilities for optimal power transfer.

Cone Material: 

The material used for the subwoofer cone affects its stiffness, weight, and response. Common materials include polypropylene, paper, and various composites. A lightweight and rigid cone material can result in better bass response and reduced distortion.

Surround Material: 

The surround material connects the cone to the subwoofer’s frame and allows it to move back and forth. Rubber, foam, and cloth are common surround materials. A flexible surround is crucial for smooth cone movement and improved overall performance.

Voice Coil Type:

Subwoofers can have single or dual voice coils. Dual voice coils offer more wiring flexibility and can handle higher power levels, providing more options for wiring configurations to match your amplifier setup.

Enclosure Type: 

The enclosure, or box, housing the subwoofer significantly impacts its performance. Common types include sealed, ported, and bandpass enclosures. Each design offers different sound characteristics, with sealed enclosures providing accurate bass, ported enclosures emphasizing low-end frequencies, and bandpass enclosures offering high efficiency and booming bass.

Best 15 inch subwoofers – FAQs

Which is better: a 12- or 15-inch subwoofer?

When you set up 15-inch subwoofers correctly, they can deliver stronger and more impactful bass compared to 12-inch subs. Moreover, these larger subs can handle more power while keeping distortion to a minimum.

Should I get a 12 or 15-inch subwoofer?

Choosing between a 15-inch subwoofer and a 12-inch one depends on your preferences and available space. The 15-inch subwoofer generally delivers greater power and covers lower frequencies, while the 12-inch sub offers a clearer and more precise sound response.

Are a pair of 12-inch subwoofers louder than one 15-inch subwoofer?

The volume produced by subwoofers is determined by their RMS watt output. When comparing two 12-inch subwoofers to a single 15-inch subwoofer, the former covers a larger surface area and generates a more forceful air push.

Nevertheless, the loudness is not solely determined by size. If the 15-inch subwoofer has a higher RMS watt output than the combined RMS watt output of the two 12-inch subs, it will produce a louder sound. Hence, both size and power play significant roles in determining the loudness of subwoofers.

What hits harder: a sealed or ported enclosure?

Ported enclosures are designed to deliver greater sound output compared to sealed enclosures due to their more efficient air volume displacement. This efficiency results in a louder and more impactful sound, allowing the ported enclosure to produce stronger and harder-hitting bass.

What Is The Best Subwoofer For Deep Bass?

If you’re looking for a good subwoofer with a strong and rigid cone and the ability to produce low bass sounds, I suggest considering the Rockford Fosgate P3D2, Rockville W15K6D4, and Skar Audio EVL-15 D2.

How Do I Get More Bass Out Of My Subwoofer?

Here are some tips to enhance your sound quality and achieve a richer bass experience:

Adjust the amp gain: To avoid any undesirable distortion in your audio, it’s essential to lower the amp gain. Distortion can adversely affect the clarity of the sound, particularly the bass frequencies. By reducing the gain, you ensure a cleaner and more enjoyable audio experience.

Optimize the low-pass filter setting: The low-pass filter is responsible for allowing frequencies below a certain point to pass through while cutting off higher frequencies. By increasing the low-pass filter setting, you can preserve the bass sounds while preventing any interference from unwanted high-frequency noise. This helps maintain a more balanced audio output, emphasizing the bass tones.

Utilize bass boost feature (if available): Some amplifiers come with a bass boost feature that allows you to enhance the bass frequencies even further. If your amplifier has this option, you can try enabling it in moderation to add more depth and power to the bass tones. However, it’s essential not to overdo it, as excessive bass boost can lead to muddiness in the sound.

Do Subwoofers Improve Sound Quality?

Subwoofers excel at reproducing sub-bass frequencies, typically ranging from 20 Hz to 60 Hz, a range where regular speakers often struggle to perform optimally. As a result, they become instrumental in accentuating the deep, resonant beats commonly found in Electronic music.

Do More Watts Mean More Bass?

Greater wattage generally results in increased volume output. Consequently, when the subwoofer’s power exceeds that of the speakers, it allows for a potentially more pronounced bass presence.


When searching for a high-quality 15-inch subwoofer, two top contenders are the Skar Audio EVL-15 D2 and Rockford Fosgate P3D2-15 Punch. Your choice between the two depends on your priorities. For those on a budget, the American Bass E1544 Elite Series is a great option.
