With all that being said, there are also multiple subwoofer enclosure types that will each deliver different sound. The main subwoofer enclosure types we deal with are Sealed Boxes, Ported Boxes, Bandpass Boxes, as well as Free-Air Subwoofers.
Sealed Boxes: Deep and Precise Bass
Sealed Boxes are airtight subwoofer enclosures that house your subwoofer and are the best option for any music that demands tight, accurate bass. With a sealed box you can expect flat response meaning your bass won’t be excessively boomy, but you will have deep bass extension and superb power handling. Sealed subwoofer enclosures tend to require more power than ported boxes so you’ll need to use an amplifier with lots of wattage and RMS to deliver optimal performance.
Ported Boxes: Forceful Bass
A Ported Box is different from a sealed box in that we use a vent, or port, to reinforce low bass response, which gives it more output than you would get from a sealed box at any given amplifier wattage. Ported Boxes tend to work best when listening to rock, heavy metal, or any other hard driving music. Typically, a ported box will deliver deeper bass than a sealed box; the downside is that you are going to need a much larger box to get that sound than you would if you went with a sealed box.
Bandpass Boxes: Ultimate Slam
If you have a specific range that you’re looking to create the maximum amount of slam in then you should consider getting a Bandpass subwoofer enclosure. In a Bandpass box the subwoofer is mounted in the middle of a 2-chamber box with one chamber being sealed and the other on being ported where the sound waves emerge from the ported side of the box. Bandpass subwoofer enclosures are highly efficient within their narrow range and tend to deliver the satisfying, earth-shattering booms that many clients are looking for. These boxes are ideal for rap, reggae, and hard rock. Be cautioned though, not all subwoofers are ideal for Bandpass boxes, and if you’re wondering which subwoofer would be ideal for this kind of setup consult with your local Reno car audio experts at Custom Concepts of Reno.
If you don’t want to take up precious cargo space with a subwoofer enclosure then you would be a candidate for a free-air subwoofer. Essentially, these systems consist of woofers mounted to a board that is attached to a rear deck or they are placed in your trunk against your rear seats. This allows the trunk of your car to act as the enclosure that isolates the sound emitted from the back of the speaker, which solves the noise cancellation issue mentioned earlier. Free-Air woofers save space, are easier to install than woofers requiring a box, and tend to have a flat frequency response, but you need to get a woofer that is specifically designed for free-air use. Also be aware that their power handling levels are usually much lower than subwoofers requiring a box.
