I am projecting a small pair of loudspeakers.
The use will be with a computer. Perhaps with an amp of 20W inbetween the two.

I have 2x100W 2" tweeters and 2x40W 4" car loudspeakers. Brands are good enough.
The enclosure is about 220mm (height), 142mm (width) and 143,8mm (depth).
It will be constructed with 9mm MDF.

Big question right now:

Do I go for the sealed design or do I go for the ported design?
I already know the pros and cons but I heard that some are particularly better with different kind of application.
Please answer ASAP, because I will be finishing the CAD models tonight and tomorrow I have to hand over the cabinetmaker.

Most car speakers end up in the dash or the doors where the air volume is finite. The car trunk is usually reserved for the back volume of a subwoofer where again it is often not exactly infinite. It is not uncommon at all for there to be dedicated sealed volumes for car speakers.

[I have no idea why you included that picture of a car door speaker. If you were trying to make a point with it, please verbalize it.


The closed mind could not see the built-in enclosures.



There is no built-in enclosure in that image, at all, just a speaker being held in front of a typical door cavity with a bracket.
