How To Choose The Best 18 Inch Subwoofer

What Is The Purpose Of An Inch Subwoofer?

An inch subwoofer is a type of loudspeaker designed specifically for small spaces. While most speakers are built with a specific size in mind, these smaller models are designed to fit into tight areas where there isn't room for larger speakers. Because of its compact design, an inch subwoofer has a low profile which makes it ideal for placement near walls or other objects. Its portability makes it easy to transport around the house or apartment.

How Does An Inch Subwoofer Differ From Other Speakers?

In addition to being portable, an inch subwoofer is also lightweight. Most speakers weigh between 10-15 pounds while an inch sub weighs only 2 pounds. This makes it easier to carry around and set up anywhere. Another benefit of using an inch subwoofer is that it doesn't require large amounts of power. Many subwoofers take advantage of passive radiators which allow them to operate quietly. Passive radiators also reduce distortion making them more suitable for high fidelity audio systems.

What Are Some Applications For An Inch Subwoofer?

Because of its small size, an inch subwoofer is perfect for applications where space is limited. If you're planning on setting up a stereo system in a living room, bedroom, or bathroom, an inch subwoofer could be the right choice for you. Since it's so light weight, you can easily bring along multiple units to different rooms throughout the house.

Are There Any Drawbacks To Using An Inch Subwoofer?

While an inch subwoofer offers many benefits, it does have drawbacks. One drawback is that because of its small size, it tends to produce lower volume levels compared to larger speakers. However, since it's meant to fill small spaces, it's unlikely that you'd notice any loss in sound quality. Also, due to its small size, it's harder to connect to external amplifiers.

Is An Inch Subwoofer Right For Me?

The answer depends on whether you plan on placing your unit close to walls or other obstacles. If you intend to position your subwoofer next to a wall, you might run into problems. Depending on the model, an inch subwoofer may not be able to handle the pressure created by mounting it directly to a wall. Therefore, you might want to mount it to something else like a shelf or stand. If you plan on positioning your subwoofer away from walls, you shouldn't have any issues.

First, you must decide whether you want a passive or active subwoofer. Passive subs require no power source other than the electrical outlet, while active subs require a separate amplifier. Next, you must determine which type of woofers you prefer.

There are two types of woofers available today: cone and dome. Cone woofers are more efficient because they produce higher frequencies with lower distortion levels. Dome woofers are cheaper, but they cannot reproduce high frequency sounds as well as cones. Finally, you must choose between sealed and ported enclosures. Sealed enclosures sound best due to their ability to block outside noise, while ported enclosures allow more bass to escape.

Passive vs Active Subwoofer

There are pros and cons associated with each style of subwoofer. Passive subs are generally easier to install, since they only require a single wire connection to the wall socket. However, these subs lack the power needed to drive larger speakers. An active subwoofer has its own dedicated amplifier, allowing it to deliver greater volume. While most active subs are designed to be placed inside the cabinet of a stereo receiver, many manufacturers now sell stand-alone models. Stand-alone units provide superior performance and flexibility, especially if you plan to upgrade your audio components later on.

Cone vs Dome Woofers

Cones are typically more expensive than domes, but they are far more efficient. Cones are able to reproduce higher frequencies with minimal distortion, while domes are capable of producing low frequencies, but distort easily. Some companies claim that cones outperform domes, but this isn't always true. For example, Yamaha claims that its VX series of subwoofers uses both cone and dome drivers, resulting in a combination of the best qualities of each design.

Sealed vs Ported Enclosures

Portable enclosures are ideal for outdoor applications where weatherproofing is required. Their portability makes them perfect for camping trips, tailgating events, and backyard parties. Unfortunately, portable enclosures aren't very effective indoors. Most manufacturers recommend using a sealed enclosure whenever possible. Seals create a tight seal around the driver, preventing outside noise from entering the unit. Although sealed enclosures are slightly louder than ported ones, they still perform admirably.

Once you've decided which model of subwoofer you'd like to purchase, you'll need to narrow down your options based on price, features, and size. Price is obviously the most important factor to consider, so shop around until you find a deal you love. Features include adjustable crossover settings, built-in amplifiers, digital controls, and remote control capabilities. Size refers to the overall dimensions of the subwoofer, including height, width, depth, and weight.

The size of the room determines whether you need two subs or three. If you're planning on using multiple speakers, you might be able to fit more than one pair into a smaller room. However, if you plan on placing the subwoofers near each other, you'll probably only need two.

Power Rating

The power rating refers to the amount of wattage needed to drive the woofer. Most manufacturers list both peak and continuous ratings. Peak power is measured during short bursts of high volume music while continuous power is measured continuously throughout long periods of playing music. Both types of power ratings are important because they determine how loud the subwoofer can play before overheating. High-quality models typically have higher power ratings than lower quality ones.

Wiring Options

Most subwoofers include RCA jacks so you can connect them directly to your amplifier or receiver. Some models allow you to run separate wires from the amp/receiver to the subwoofer. Others require you to splice the wire together inside the box. Splicing is easier, but it takes longer to set up. Make sure you know which type of wiring option you prefer before purchasing.

Frequency Response

This number indicates the range of frequencies the driver can reproduce. Higher numbers mean greater clarity and detail. Lower numbers indicate poorer sound reproduction. Many brands claim a frequency response of 50Hz - 20000 Hz. But many drivers actually cover a wider range, especially those designed specifically for car audio systems. Check the specifications carefully to ensure you're getting what you pay for.

Crossover Frequency

Some subwoofers have built-in crossover networks that adjust the output based on the input signal. Crossovers are useful for improving bass performance by reducing distortion caused by low-frequency signals being amplified too hard. Crossovers are generally adjustable, allowing you to fine tune the transition point where the woofer starts amplifying mid-range sounds and stops amplifying bass.


Subwoofers vary greatly in size. Smaller units are great for small spaces or areas where there isn't enough clearance around the cabinet. Larger cabinets are good for larger rooms or areas where the subwoofer needs to sit farther away from walls and corners. Be aware that bigger boxes take up more floor space and may interfere with furniture placement. Also, remember that the deeper the subwoofer sits, the louder it plays. So, if you're going to put it deep, you'll need to raise the height of the stand to compensate.


Many subwoofers are available in black, white, silver, gold, red, blue, green, purple, orange, yellow, pink, gray, or combinations thereof. Black looks sleek and professional. White makes the unit appear light and airy. Silver gives the appearance of luxury. Gold accents give the impression of wealth. Red is bold and eye catching. Blue is calming and relaxing.

Subwoofers are speakers that produce low-frequency sounds. The most common type of subwoofer is called a sealed box. Sealed boxes are typically built into the floor of a room. If you're building a custom soundproofed room, you might be able to install a sealed box directly into the wall. Another option is to build a subwoofer enclosure around a sealed box. Enclosures allow you to mount the subwoofer anywhere in the room where there's enough space to accommodate its size. Most enclosures include mounting hardware so you can attach the subwoofer to the ceiling, walls, or other parts of the room.

Headroom refers to the amount of additional voltage above the nominal supply voltage required by the amplifier. To determine the minimum headroom needed, divide the total power delivered by the amplifier by the specified input resistance of the woofer. So, if the amplifier delivers 60 watts RMS at 1/2 Vrms, the amplifier needs at least 30 volts of headroom.

Crossover Point

The crossover point is the frequency at which the woofer begins producing lower frequencies. At higher frequencies, the woofer acts more like a regular loudspeaker. As the frequency increases past the crossover point, the woofer starts acting more like a conventional subwoofer. Crossover points vary depending on the design of the woofer. Some designs have multiple crossover points. Others have only one crossover point.

Low Frequency Response

As the frequency decreases below the crossover point, the woofer becomes increasingly efficient. Efficiency refers to the ability of the driver to convert electrical signals into mechanical motion. Drivers become progressively inefficient as they approach resonance. Resonance occurs when the mass of the diaphragm reaches a critical value. Below resonance, drivers act like springs rather than moving masses. Because the springiness of the driver changes dramatically as the frequency approaches resonance, the efficiency of the driver drops significantly.

High Frequency Response

Above the crossover point, the woofer behaves more like a conventional loudspeaker. Above the crossover point, the woofer's sensitivity to high frequencies diminishes because the air pressure inside the cabinet is no longer changing rapidly. Typical values for high frequency ranges begin at approximately 2 kHz and end at approximately 10 kHz.

Woofer Size

Most manufacturers specify the number of inches across the front face of the woofer cone. Manufacturers also list the diameter of the voice coil. Voice coils are wound wire loops that carry current to create magnetic fields within the magnet structure. The larger the voice coil, the greater the force exerted on the magnets.
