Ported to Sealed box

[Hartman]

I have a ported box right now, and the subs hit pretty hard but I am under the impression that sealed boxes are better. Could I make some circle cutouts out of MDF and plug up the holes to make it a sealed box? Is this practical or worth doing?

Suggestions wanted.

From, everyone who I have spoken to, ported is way better and the sub can hit a LOTTT harder because of all the air that it is allowed to come into contact with. I only way people dont go ported that i know of is because, 1. the ported box takes up more room, 2. cost more to make, 3. has no idea what they are doing, 4. never heard the same subs in a ported box. 5. they are running sealed subs under their seat in their truck (ported would be rather hard there)6. they are running like 4+ 15's and the bed of their truck doesnt have the room for them to be ported.

Hartman...here is what I believe to be the best thing to do...only if you are going to stay sealed and not re-port. First...cut off the tube inside of the box. Then...as you said...make a little circular plug to fit inside. Then take some scrap wood and place it on the inside of the box(covering the hole, this way it gives your plug the proper height and something to brace it with). I would then use some wood glue or liquid nails to seal up the brace. Also...if you can, try to get a screwgun in the box and shoot a couple screws up into the brace. Then on the outside use some silicon to seal around the plug.

There may be an issue here dealing with the required air space for the sub installed in a ported box versus a sealed box. The interior volume required by the sub is larger for a ported box than it would be for the same sub installed in a sealed box. This is why ported boxes are usually so much larger than sealed boxes. The subs require more airspace when used in a ported application. Having too much air space in a sealed box may hamper the sub's performance.

If I were you, I would read the required specs for the sub and see how much the difference is between the required air space for the two different box designs. For optimum sub performance, you'll want to have as close to the recommended volume of air as you can. I'm not a sub expert, but that's my take on it.
