Buyer’s Guide

Just imagine how deep, clean, and smooth bass can really be with a functional and durable subwoofer. If you are lucky to find one that suits your objectives perfectly, your experience isn’t likely to be ever lacking. High-precision sound is far from the only feature to look for. It is also important to pay attention to several other parameters as well to make the right choice. For those who can’t imagine their life without making their music richer and more voluminous at low frequencies, the following recommendations will come in handy.


The quality of technologies and materials applied should be second to none, but these indicators are pretty hard to check at your end, especially during online shopping. In this perspective, to go for products from well-known companies that care about their reputation means winning a jackpot. Loud play and longer performance time are guaranteed by brands from our top-5 list.

Besides, customers can take a look at the models by Pioneer, Kenwood, JL Audio, JBL & Infinity, Rockford Fosgate, Kicker, etc. However, by giving your support to any of these brands, you agree to follow their pricing packages. Since some brands offer only premium-class solutions but others are focused on average specifications mainly, it will help you make a final decision in terms of the balance of price and quality.

Enclosure Type

Of course, it is always better to select models which are more universal when it comes to installation. When you have an opportunity to choose between sealed and ported enclosures, you get a higher degree of flexibility too. However, please consider the sound depends on the enclosure type greatly. In the first case, the deepest base will be generated without difficulty. In the opposite scenario, higher levels of volume will be necessary for the same results as with sealed boxes.

Single vs. Dual Voice Coils

It is more advisable to pick up dual voice coils since they offer more room for further updates of the audio system. For instance, single voice coil solutions won’t allow you to add additional sound outputs. However, such equipment is more beneficial in terms of quick and hassle-free installation.

The ohm-rating of voice coils is to be analyzed too. In general, the majority of models present are four-ohm in impedance balance, but there are two- and eight-ohm alternatives. Make sure the compatibility criterion isn’t messed up.

Frequency Range

The rule of thumb is simple in this case: the lower and more accurate the range of frequencies is, the better the result of sound reproduction will be. Usually, human’s hearing can’t actually identify frequencies under twenty Hertz, they can be felt. If you are a listener with exceptional hearing, then sounds not lower than twelve Hertz won’t seem competing to you. The upper end is typically limited at the point of two hundred Hertz.


A lot of people think that the choice of a more powerful solution results in a more satisfactory sound loudness, but that’s not correct. Go for checking RMS ratings only to find out how efficient this particular subwoofer is when it deals with power handling during prolonged periods. For small spaces, power hitters may be simply unnecessary.

Moreover, if you decide to pick up a super-powerful woofer, please be ready to look for compatible amplifiers as well. High wattage requires considerably more power to be driven.


Is there any difference between sealed and ported woofers in terms of sound loudness?

In general, this parameter depends more on the quality of the product itself, but the location is meaningful too. Vented enclosures are that one option that allows achieving boomy music.

What is the most functional subwoofer for sound quality?

Solutions from Alpine, Rockville, Orion, and other premium-class brands are deeply appreciated by customers and highly evaluated by specialists in the field of the professional bass sound.

The Bottom Line

Either home audio or car audio systems, good bass is one of the first things to notice. If the wow-effect achieved through awesome low-end performance is what you expect to get from your subwoofer, feel free to stick to the tips and recommendations above — they will help you purchase the safest and most functional bet in your music experience.
