Sealed to Ported

A friend of mine has a sealed box that he made himself out of 3/4" MDF and he's wondering what all it would take to change his sealed box into a ported box and actually sound good.

Re: Sealed to Ported

Depends on whether or not he wants tube or slot port, and what the enclosures volume is. IF its to small then it wont matter how much your port it cause it would be to small.

Don't ever look at cars as just imports or domestics. Just because a car is made in a certain country doesn't mean that it is anything like another car from that country. An example of this is Mitsubishi reliability, just because they are Japanese doesn't mean that they are as reliable as a Honda or Toyota.

Re: Sealed to Ported

Well, basically your TRUNK is a sealed box, and having a ported box inside your "sealed box" would sound better, the sub usually tells you the recommanded size of box, and you can port it however way u want

Re: Sealed to Ported

No your trunk does not act as a sealed enclosure, the only way this works is if you make it a sealed enclosure for either a free air sub setup or for a set of speakers.

As for the ported slot ports are the best.

Re: Sealed to Ported

Hence the reason for 1" think lexan for pure spl vehicles, and extra 100-200lbs of weight from sound deadening, or in some cases concrete.

Re: Sealed to Ported

Best way is to measure the volume and then determine what you want it ported to, then get the required amount of tube and drill the hole in the top and mount the tube.
