The Sound Town METIS Series 18-inch Powered Subwoofer packs a punch in terms of overall loudness and power. It has a built-in Class-D amplifier and can deliver 700 Watts rms rating and 2400 Watts Peak Power. This is the choice for you if you want a powered subwoofer that will create a genuinely thundering sound.
The Sound Town sub provides a powerful bass and delivers on the low frequencies thanks to the 4′′ voice coils. Furthermore, the cabinet is constructed of durable, high-quality materials, ensuring that it will withstand long journeys.

Unfortunately, the frequency response range of this 18-inch Sound Town METIS series subwoofer is somewhat limited.

18 Inch Subwoofers Buyer’s Guide
The size of the sound will depend on how powerful your subwoofers are.
Manufacturers will use power ratings to rank their items on the market.
Each model’s power ratings are broken down into two categories: peak power and power RMS.
Why are speakers and automobile subwoofers given two different ratings?
The max wattage is the power output your 18-inch subwoofer can manage in short bursts.
We comprehend why it may be simple to become distracted by the astounding number because the peak power handling is greater than the RMS power.
It’s not advisable to continuously drive your subwoofer at its maximum power level, though.
Buyers should focus on the RMS power rating.
The RMS rating, which is frequently half that of the peak, is the level at which you can play music without running the risk of damaging the high excursion woofer, the large voice coil, or the cone.
High RMS and power ratings can be delivered by a top-notch subwoofer.
Our team of sound engineers advises using the power of more than one sub to produce the sounds you need if you ever need extra force.
Aesthetics and Bass
The technology and frequency range of the subwoofer are key factors in its capacity to deliver high-quality audio.
It is not required for a subwoofer to go all the way down to 20Hz because humans have trouble hearing anything below that frequency.
The purpose of a subwoofer is to bring low sounds to the forefront, and premium devices are capable of doing so at both high and low levels.
Our group advises searching for an 18-inch subwoofer capable of reproducing sounds beginning at 30Hz.
The materials chosen will also affect the sound quality.
The bass will be propelled by a ferrite motor, and bass excursion will be supported by a sturdy cone with the ideal balance of rigidity and flexibility.
Ensure your 18-inch subwoofer has adequate ventilation so the low frequencies can travel far without losing quality.
The weight of the cabinet must also be taken into account in addition to the raw subwoofer weight. It goes without saying that the greatest 18-inch subwoofer weighs more than smaller models like the ones we selected from the REL Acoustics subwoofer company. For limited space, the 18-inch subs aren’t the ideal option. Nonetheless, the audio from these subwoofers will amplify songs with multiple layers and improve the factory car speakers.
When installing a sub with an outside diameter of 18 inches in your vehicle, you should be aware that it could easily weigh 60 pounds or more. While 18-inch subs are less transportable, once you put them in the cabinet, they will remain there. Especially if you plan to connect more than one of these subwoofers to your automobile, pay attention to the weight. To make the cabinet a little bit easier to move about, you can consider adding ergonomic handles. The weight will also depend on whether your subwoofer is powered or passive. A powered subwoofer is simpler to connect but will weigh significantly more than a passive subwoofer because it has an integrated amplifier.
Design and Components
Ideally, your 18-inch car subwoofer comes with a shallow installation to free up more room. Certain subwoofers perform better in sealed enclosures, while others perform better in ported ones. Although sealed subwoofers naturally produce less deep bass, they provide better audio clarity and precision. The frequency response performance is unaffected by the enclosure type, but if you desire greater bass at the expense of accuracy, our staff advises mounting your 18-inch car subwoofer in a ported cabinet.
The longevity of the automobile subwoofer is correlated with the materials used to build it. An 18-inch subwoofer with a die-cast aluminum basket, KSV voice coil, and a Kevlar  reinforced cone, for instance, outlasts ones composed of inferior materials. Stronger material isn’t necessarily better if it doesn’t allow for the cone to move about, say our sound engineers.
Also, you must pay attention to the cabinet’s construction material. Cabinets made of MDF or high-quality wood will assist reduce resonance, vibration, and distortion. Increased low frequency extension will also be supported by larger enclosures.
Installation for a subwoofer this size can be challenging. If you know what to look for, according to our experienced audiophiles, the setup hassle can be minimized. If you choose a passive type, be sure your 18-inch subwoofer is compatible with your amplifier. Your system as a whole should benefit from the subwoofer’s frequency response. Also, the connection must be compatible with your speakers, and the terminals must be extremely robust and temperature-resistant.
We all appreciate high-quality audio, but the greatest sub on the market with great bass relays can be rather expensive. Our testing team went above and above to add a subwoofer choice that is both high-quality and affordably priced. Avoid selecting a subwoofer only on the basis of price. It can wind up costing you much more if you later need to replace it.
