Can a box be too big for a sub?

Remember, there is such a thing as too big. As the size of the enclosure increases, the mechanical limits of the woofer will be easier to reach. If the box is too small (by a reasonable amount) add power. … If the port becomes too small, it may result in port noise, or allow the woofer to simply unload.

How do you calculate air space in a sub box?

You simply measure the height, width and depth (in inches), multiply them together and then divide that number by 1728. If the box has internal measurements of 6″ high*18″ wide*12″ deep then the volume of the box is 1296/1728=. 75 ft^3.

Do ported sub boxes hit harder?

Ported boxes use a vent (called a port) to reinforce low bass response. You get more output than you would from a sealed box at any given amplifier wattage. … Ported boxes can deliver deeper bass than sealed boxes, though they need to be much larger than sealed enclosures to accomplish that.

What happens if a sealed box is too big?

Sealed boxes will generally losen the air pressure inside, thus slowing down the woofer, thus reproducing a lower frequency. However after a certain point, it will become sloppy uncontrolled, and sound like trash.

How do I make my subs hit harder?

You can also make minor upgrades to your subwoofer to make it hit harder. Change the small cone in front of the subwoofer, change the voice coil or get a new enclosure for the subwoofer.

Can I port a sealed box?

You can place a port in your now sealed box. A simple hole saw and drill will do the trick nicely. Youll have to determine the net cubic air space. (net= space left after the subwofer is in) Then determine what tune frequency you want to port the subwoofer at.

Which way should subs face in trunk?

Facing the Boot – Rear of the Car

This is the most common direction used by the majority of custom car audio fanatics. By placing the subwoofer in the trunk against the last row of seats, facing away from the driver, the bass becomes more pronounced and evenly distributed across the car’s surface area.

Is a ported box louder than sealed?

PORTED / VENTED SUBWOOFER ENCLOSURES

These types of enclosures, when built with the properly calculated volume and tuned to the correct frequency for the subwoofer, are generally louder than a sealed enclosure. … They allow subwoofers to reproduce the lower frequencies found most often in Rap and Hip Hop music.

Should I put polyfill in a ported box?

It is possible to use polyfill in a ported enclosure, but this is not recommended, as it would then change the tuning of the box. Sealed subwoofer boxes generally yield a better, flatter frequency response curve when the enclosure is larger (to a certain point).
