Why Buy a 15-Inch Subwoofer

Modern speakers are better than ever, but they can’t deliver the bass like subwoofers. They can’t dig deep into the lowest frequencies to provide accurate bass and clear sounds. And while subwoofers can do that, the true rulers of low frequencies are the 15-inch subwoofers.

The 15-inch subwoofers have the size and power to move lots of air, all at once, to give you the deepest bass. Get to experience sound clarity, play as loud music as you like without distortion, and get surround sound seamlessly blended with full-range speakers.

Factors to Consider When Purchasing 15-Inch Subwoofers

Every 15-inch subwoofer should have the following key features:

Power

More subwoofer power equals deeper and more prominent the booms. Power rating is in two ways; RMS and peak power outputs. The RMS power shows the power the subwoofer can handle continuously, otherwise the speaker output, while peak power shows the highest wattage the sub can run in short outbursts. Therefore, the RMS rating is more realistic and takes preference over peak power. Also, ensure the subwoofer power matches your amplifier’s power output.

Frequency Range

Deep and clear bass happen at low frequencies. Thus, a subwoofer that can achieve very low frequencies is the best for you if you like heavy bass.

Sensitivity

Sensitivity, measured in decibels, shows the efficiency of a subwoofer to produce sound with a given power range. For the best results, high-sensitivity subwoofers should go into low-powered audio systems and vice versa.

Impedance

Most 15-inch subwoofers have 2ohms and 8ohms impedance, but they’re also some with 4-ohm ratings. So when deciding on the best subwoofer to buy, go for the one with matching impedance and power rating to your amplifier. 

Number of Voice Coils

Subwoofers feature either a single or dual voice coil (DVC). Most high-end 15-inch subwoofers have DVCs, as they allow for better wiring flexibility. DVC subwoofers are relatively pricey, but most users love them for their power.

Enclosure Type

The type of enclosure determines how loud and how deep and accurate your subwoofer can go. Sealed boxes produce the most profound and more precise sound. However, bandpass and ported enclosures are the loudest.

Types of Subwoofers

Below are the subwoofer types you’ll encounter while shopping:

Powered Subwoofers

Powered subwoofers contain a woofer and a built-in amplifier as a single unit. They are compact and won’t occupy a lot of space. Powered amplifiers output very impressive sound. However, their small amplifiers and drivers won’t provide a big bass as some audiophiles would like.

Component Subwoofers

A component subwoofer is a speaker itself. It needs mounting in a subwoofer box and an external amplifier to produce quality sound. They come in varying designs and sizes to fit various box types, and some are specifically for use in high or low power settings.

Enclosed Subwoofers

An enclosed subwoofer comes pre-mounted into a box specifically designed to accommodate the subwoofer. Of course, you won’t go through choosing an ideal enclosure, but you’re also stuck with the shape and box type the subwoofer comes with. You’ll also need an external amplifier for enclosed subwoofers.

Vehicle-Specific Subwoofers

These subwoofer types have specific designs to fit in various locations in vehicles. They come color-matched with the vehicle’s interiors and may work in areas other subwoofer types can’t fit without modification. However, just like powered subwoofers, vehicle-specific subwoofers won’t give that big and deep bass.

Tips and Tricks in Dealing with 15-inch Subwoofers

Below are tips to help you get the best experience with your 15-inch subwoofer:

  • Install your subwoofer in a dust-free area as dust negatively affects the sub’s performance and may shorten its lifespan significantly. When tidying up, rid the subwoofer of all dust using either a blower or vacuum cleaner.
  • Install the subwoofers away from magnetic metal parts. Use wood or non-magnetic materials instead to avoid the negative effect magnetic metals have on the subwoofer’s electromagnet.
  • Read and understand the user manual before installing your subwoofer. It’s good to hire a professional if you’re a beginner, especially if you’re using the subwoofer in your car. So you don’t misconnect the wires and end up blowing up the entire audio system.
  • Install the subwoofer in a well-ventilated space. Good ventilation lengthens your subwoofer’s durability.

15-inch Subwoofers FAQs

What box type is the best for my 15-inch subwoofer?

There is no direct answer as each box type, otherwise known as an enclosure, has its strengths. There are three box types-sealed, bandpass, and ported boxes.

Sealed boxes have only one opening for the subwoofer’s head and have no other outlets for allowing air in and out. As a result, they give precise and clean sound, and their compact sizes make them ideal for use in vehicles. However, subwoofers mounted on sealed boxes require more power to produce higher volumes.

Ported boxes have single or multiple air spaces. Subwoofers mounted on ported boxes produce bigger and louder bass than those on sealed containers. The airflow also acts as a coolant for your subwoofer. Ported boxes are ideal for heavy and continuous use subwoofers.

Bandpass boxes are similar to ported boxes but designed for louder sound. They feature two chambers- a vented one and the other enclosed. They are excellent for subwoofers meant to play aggressive music often.

What is the difference between a 2-ohm and 4-ohm subwoofer?

Impedance is a measure of the electrical resistance of the voice coil(s). It directly affects the sound volume of the subwoofer. At the same power input level, a 2-ohm subwoofer will be louder, but a 4-ohm subwoofer will produce a better and more compact sound.

How much power do I need to power my 15-inch subwoofers?

The amount of power you need is dependent on the RMS rating of the subwoofer you are looking to buy. Unless you want to buy another amplifier, ensure your amp and subwoofer match the RMS rating and the impedance.

Will putting my subwoofer in the trunk affect the bass?

It depends on the power of your subwoofer. Clear and loud bass sounds travel through most materials with ease. So, as long as the subwoofer is of good quality, having it in the trunk doesn’t affect the bass.

Can I install my 15-inch subwoofer myself?

Yes. Installing subwoofers is easy as long you follow the instructions correctly. Even so, the process is specific to the subwoofer type and brand. If you’re a novice, getting an expert will yield better results.

Do I need an amplifier to power my 15-inch subwoofer?

Yes. Audio systems alone lack enough power to get the best sound out of a subwoofer. So you’ll need an external amp to provide the subwoofer with the required energy. But the subwoofer is the powered type; you won’t need to buy an external amplifier.

How do I match the impedance of my subwoofer with that of the amplifier?

Matching a subwoofer with the right amp is straightforward. Connect a 2-ohm sub with the 2-ohm amplifier’s speaker output-the same with the 4-ohm and 8-ohm subwoofers. A mismatch in the impedance damages the amp’s circuits, resulting in distortion and loss of sound quality.

Final Thoughts

15-inch subwoofers are bass kings. While most produce quality voluminous bass, not all can win in a precision and power balancing challenge. And our top pick for the best 15-inch subwoofer among those we reviewed is the Pyle PLPW15D. This has not been an easy top pick and of course your mileage may vary. However, the heavy-duty magnet and a high-temperature resistant dual voice coil deliver a cutting-edge well-balanced bass. If you like it loud, the 2000W max power makes this subwoofer equal to the task. Pyle has taken their time to give this sub-premium-built and performance at a favorable price.
