Planet Audio Subwoofers Review | Everything You Should Know

Subwoofers are speakers that are primarily used for reproducing low-frequency bass sounds, as opposed to regular speakers. Not all speakers are designed to reproduce low-frequency sound, which is the type of sound that will provide the listener with a terrific listening experience in the first place.

A good, powerful subwoofer can relieve your loudspeakers of some burden to produce sound. The addition of a subwoofer would significantly increase the stereo imaging, as well as the accuracy of the sound. In general, a subwoofer contributes to the production of a more even, louder, stronger, and clearer sound overall.

Everything You Should Know About Subwoofers 

For your feasibility, we have compiled all the useful information in this article along with the planet audio subwoofers reviews. Before choosing one, we will suggest you look at the following guide:

Peak Power

Never get confused between “peak power handling” and “RMS power handling” ratings. Rather than reflecting realistic operation, peak power is a measure of how much power can be generated or handled in brief bursts over a long period of time.

Some manufacturers emphasize peak power levels on their subwoofers and amplifiers by embossing these figures on the products. As previously stated, peak power ratings are not indicative of the true power capability of the equipment in question.

Note: After making a comparison between the RMS power rating of the subwoofer and the power handling of the amplifier, you will have all the information you need to select the appropriate equipment.

RMS Rating

The RMS power of a subwoofer is the most important factor to consider when purchasing one. When it comes to subwoofers, the RMS indicates how much power and sound they can output at a consistent and optimum rate for longer periods of time without causing distortion or harm to the device.

  • Users must match the RMS power of their subwoofers with the RMS output of their amplifiers in order to get optimal performance.
  • Create a match in order to safeguard the subwoofer and to get the greatest performance and sound output from the subwoofer.
  • As a rule of thumb, if you buy a sub with an RMS rating of up to 250 to 500 watts, make sure that your amplifier can also handle 900 watts of RMS.

Frequency Response

The frequency response is measured in Hertz. Humans are capable of detecting audio waves with frequencies ranging from 20 to 20,000 hertz. Furthermore, the frequency response is essentially the audible vibration measured in Hertz, which is what the term refers to.

  • The purpose of a subwoofer is to generate low-frequency sound waves ranging from 20 to 200 Hz, while it is advised that this frequency range be kept below 100 Hz by using a crossover filter.
  • Some subwoofers will have an adjustable bass level, which will allow you to dial in the right amount of power for those low-frequency frequencies.

The following infographic will help you in understanding it better:

Frequency Range Of Subs

Sensitivity Rating

The sensitivity rating refers to the sound produced at one meter from the speaker by one watt of electricity emanating from the amplifying device. It assists you in determining the amount of power you require from an amplifier.

  • In this case, the sensitivity rating of the subwoofer is measured in decibels (dB).
  • If the subwoofer has a high sensitivity rating, it will play louder once the wattage of the system exceeds a specified threshold.

Mounting Depth

Keep in mind the manufacturer’s recommended enclosure size, especially if you don’t have a lot of available space. The box volume will tell you how big your enclosure has to be in order to work properly.

  • Ideally, you should establish the minimum size of your box by subtracting 2 inches from the depth of the subwoofer.
  • A passive subwoofer requires an enclosure in order for your speaker to be successful, and the depth of that enclosure will have an impact on the goods that you can choose from.

Sound Quality

Make certain that your subwoofer is properly wired in order to obtain the highest and finest overall sound quality from the device. If you follow these instructions, you can hear every detail of what is being played on your favorite music. You must understand what is most important and how it can affect the punchy performance of your car stereo.

When attempting to enhance the quality of an exclusive set up in an enclosed environment, factors such as frequency range, enclosure, and wiring requirements for matching amplifiers are all worth considering!

Several options that include the subwoofer, the amplifier, and the enclosure have been included for your convenience. These options provide car stereo system matching that gives excellent sound quality from the manufacturer’s speakers.


The enclosure of a subwoofer is an important factor to consider in addition to the components and internal parameters of a subwoofer. It is the shell of the subwoofer that contains all of its internal components, which is referred to as the enclosure.

  • The type of enclosure is also important since it prevents sound from escaping and absorbs vibrations that could interfere with the functioning of the subwoofer’s drivers.
  • However, while the enclosure should be capable of doing so, it should also offer an adequate amount of airflow to the drivers in order for any extra heat to be dispersed as quickly as possible by the fans.


The internal resistance of a circuit is the resistance that prevents electricity from flowing freely through it. This impedance is measured in ohms, and the impedance rating can be found on any audio-related equipment, including headphones, in-ear monitors, and subwoofers.

  • It is necessary to know the impedance of a subwoofer in order to determine whether or not it will work with a specific amplifier.
  • It makes no difference if you have a subwoofer with an impedance of 2, 4, or 8 ohms as long as you connect it with an amplifier that can handle the same impedance.

The following infographic will help you understand the difference between impedance and frequency:

impedance vs. frequency

8-inch Subwoofers vs. 10-inch Subwoofers: Which is better?

Although the difference in usable speaker diameter between an 8-inch and a 10-inch subwoofer is only two inches, the difference in power handling and overall qualities can make a significant difference in the overall performance. However, due to the fact that two subwoofers of the same size may be constructed in radically different ways from one another, you will discover that there are more crucial considerations when it comes to subwoofers than simply cone size.

Note: The answer is the same if you differentiate between 12 and 15 inches subwoofers.

Voice Coil Diameter

Voice coils for subwoofers with 8 and 10 inches diameters will frequently be of different sizes.

  • The voice coil is the metal wiring that converts amplifier power into an electromagnetic field, which causes the driver to travel forward and backward in its position.
  • The size of the voice coil is frequently directly proportional to the amount of power it can handle.
  • Remember that, you should always pay more attention to power handling and low-frequency performance represented in hertz rather than merely speaker size when purchasing speakers.

Voice Coils

Frequency Range Expansion

When it comes to low-frequency extension, hertz is the unit of measurement, and you want the lowest possible value. If a subwoofer lowers to 18 hertz, for example, it will create more low visceral bass than a subwoofer that descends to 22 hertz will. This holds true regardless of the cone’s surface area.

  • Because of the way speakers respond in enclosures, the size of the enclosure in this scenario frequently has a greater impact than the size of the driver.
  • Larger enclosures are typically more effective at low-frequency extension, whereas smaller enclosures save space but compromise frequency extension performance.
  • For more information on what type of enclosure the sub is meant for, refer to the paperwork included with the sub.


The amount of power that a subwoofer can handle is often reflected in the amount of movement that the driver can make, which is referred to as excursion. This is translated into the quantity of bass energy that the subwoofer is capable of producing. Consequently, because the amount of bass produced by the speaker is mostly determined by how much air it can pressurize in a given region, the further a speaker goes, the greater the amount of air it displaces. As a result, the bass is lower and more forceful.

  • In the case of two subwoofers of identical construction (eight-inch and ten-inch), the ten-inch model should theoretically displace more air.
  • Due to the weaker suspensions and materials used in lower-priced subwoofers, their excursion is typically smaller.


In automotive audio, a phenomenon is known as cabin transfer naturally enhances the bass response by amplifying the bass response. This is due to the fact that the listener is seated in a very compact space. In this situation, a single 8- or 10-inch subwoofer can be difficult to discern from the rest of the system. In a home audio or theatre situation, however, the size of the space is an important factor.

  • If you use a subwoofer that is too small, you will hear minimal bass.
  • If you get a subwoofer that is too large, you may either waste money or find that the sub is more difficult to install.
  • These concerns are insignificant when comparing an 8-inch and a 10-inch subwoofer since the differences are too minor to be noticeable.
  • The addition of a second identical subwoofer of either size in rooms larger than 3,000 square feet, on the other hand, can significantly reduce the natural peaks and valleys of bass response.

What Would Be Preferable?

Subwoofers with a 10-inch diameter often have a deeper bass response and better clarity than subwoofers with an 8-inch diameter. Despite the fact that it produces a significant quantity of extra bass, this size is common for a reason. If you are a fan of heavy metal, country, or rock music, a 10-inch subwoofer will meet your sound needs without depleting your bank account.

Frequently Asked Questions

What are the dimensions of a 10 inch subwoofer box?

The subwoofers intend to perform the best in an enclosure box with a specific volume of airspace. The more the size of a subwoofer, the more the volume it requires in the subwoofer box. In order to get the best out of a 10 inches subwoofer, the dimensions should be 11 x 11 x 11 inches.

How much airspace does a 10 inch subwoofer need?

A subwoofer requires sufficient room in its enclosure in order to perform efficiently and provide the desired sound. The airspace required for a 10 inch subwoofer should be between 1.0 and 1.5 cubic feet.

Does 10 or 12 subs hit harder?

In general, when given sufficient power, the two 10s are effective “As a result of the increased sound pressure generated by the combined cone surface area of the subwoofers, the subs sound cleaner and punch harder. The number 12 is a single “Sub, on the other hand, may have a deeper tone.
