Building a sub box- must be compact

[matty88]

Hey I'm making a subwoofer box for woodwork at skool... looking to put a 10in or 12in sub (havent bought it yet) and want to know if these dimensions are good. Look at the attached pic for a diagram. Using 18mm MDF.

Too big for a 10 unless it's a ported 10. Besides, you don't realy know what size you need until you buy the sub and know how many litres the box needs tobe.

But in general is it OK?

You gotta use the specifications for the sub on for its air cushion for the best sound, so buy the sub first or, if thats too much of a stretch since its for a school project, make a choice and get them to put it on hold, and note down the volume it requires for a sub box then work from there. That will get you the best performing sub. youre design looks pretty generic but sound so if you want to work from that work out the volume and then shorten the box design if you go with the 10 incher, so that you have the right cushion of air. But anything real hard with car audio you have the right person checking out your post in 12voltking :king: (dont worry mate im not gonna turn on ya again )

Im looking at putting a small 8 inch sub behind the seats in my ute, ive seen it done before. because i will be building the boxes myself, what is the minimum sized box i could have because there isnt alot of room back there. does the design of the box matter to sound quality, and would it be worthwhile porting them?

Look at the datasheet for the specific sub you are looking at getting. 12” subs are usually around 1cubic foot to I would expect it to be less than that.

A ported box will be about 2x as big as a sealed enclosure.

Have a look on the forum, I think there is a few threads started concerning subs in utes
