Looking for the ideal audio system could be difficult. Perhaps you’re searching for a subwoofer, or an amplifier, or even an enclosure. You have to know what kind of power you need to supply your subwoofer with and how big of a subwoofer enclosure you need for your installation. But there is one solution for all of these—pre-loaded subwoofer box.

The trick is finding out which out exactly what these pre-built systems could do. Often times, these combo packages are designed for car audio beginners who want to test the water without much headaches. There are tons out there now geared specifically for audiophiles such as yourself. Check out the 2008 Kicker loaded enclosures! They’re packed with features and could easily outperform most brands. The new Kicker 08TS10L72, for instance, will house one 10” Solo-Baric L7 subwoofer, capable of delivering 600 watts of continuous power and 1200 watts of peak power.

What are some advantages to these types of enclosures? First of all, the manufacturer knows what would be the best placement, size, and volume of the enclosure in order for the subwoofer to operate in a consistently optimum level. With this in mind, they have only purpose for these boxes—to make the box fit like a glove for the subwoofer. Perfection is definitely key in designing the best sounding system. Whether it would be perfect calculation, calibration, or tuning, the bottom-line is the fact that these are made for the included subwoofer.

In addition, they have also tailored these subwoofer boxes like suits, built with the best material, shape, and position possible for the subwoofer in order to achieve the best sounds possible. You wouldn’t have to measure how big the ports have to be or worry about the internal wiring. All you have to is place it where you want it, hook up the wires from the amplifier, and you’re good to go!

They have various sizes, from 8” to as big as 15” loaded subwoofer enclosures. In addition, various companies have both dual or single voice coil designs as well as single or dual subwoofer mounts. You can be sure of one thing with pre-loaded subwoofer boxes: you’ll be free of headaches and will not be disappointed!

Subwoofer Box Information For Beginners

There are many different types of boxes you can use to mount your subwoofers. I will be going over the different types of subwoofer enclosures options that you have.

Infinite Baffle | Free Air

This is going to be the easest and cheapest way to add a subwoofer to your car audio system. This setup is tipicaly done in car with small trunks and there is not very much space available. There are a few ways that this can be set up. The car subwoofers can be mounted in a large cars rear desk or behide the back seat. Basically you are using the trunk as the speaker box in this set up. Now you must make sure that the truck is completely sealed off from the rest of the car to prevent cancellation.

Sealed Enclosure | Isobaric

This seams to be one of the most popular enclosures used in SPL competition because it produces great low level power handling and require less space than most other speaker boxes need. The sealed box is the most forgiving to design errors. Now a couple of he cons of sealed boxes. You may notice more distortion at high frequency and the speaker magnet will not cool as easily as non sealed boxes. Now even though sealed boxes require the least amount of space if you have even less space than need for you sealed box for a give subwoofer you can use the Isobaric setup. This setup requires less air space in the sealed box but takes two subwoofers to get the output as if you had the one subwoofer in the correct sealed box. Isobaric is when you have a speaker mounted in a sealed box like normal but also mount another subwoofer to the first face to face.

Vented | Ported Boxes | Bass Reflex

If you are going to be making your own box, the bass reflex boxes are not nearly as forgiving as the sealed box and you will hear you design mistakes. The bass reflex or ported box is basically a sealed box with a port or vent tuned to a specific frequency. This setup has good power handling and excellent efficiency. Now the down side of the Ported box. The ported boxes can be much larger than sealed boxes. Playing a subwoofer below the tuned frequency and power handling will produce a very poor sound and will damage the subwoofer. Do not lower the port below the manufacturer’s recommended frequency, this will only make things a lot worse.

Bandpass

The most popular in SPL competition. A bandpass box is basically a port box with another enclosure mounted to the front of it with another port or vent. When built correctly will produce very high SPL. But here is the problem. Bandpass box are not for giving at all. If the box is not built correctly it will a total waste of time and money and sound horrible. Bandpass boxes have to be tuned for a narrow bandwidth of frequency response. Suboofers are susceptible to cone over-excursion for frequencies outside of the tuned frequency response, and even worse if below. Please make sure to use a very good crossover to keep the frequency response in the correct range.
