Sub enclosure for 10"

[carshateme]

Decided I'm done with Sealed boxes...Just not getting the bass I want out of them. So I'm building a new box, just want some recommendations for it.


Ported series

(I didn't add the slants in the pictures. But I am putting them in the corners.)

dimensions are 33"w x 13.5"h x 26"d
Sub hole cuts 9.5diameter
Port hole is 4" x 11.5"



Or...

dimensions are 33"w x 13.5"h x 26"d
Sub hole cuts 9.5diameter
Port Hole is 4" x 7.5"

1st design-the ports will add bracing to the enclosure, personally I'd do a common chamber and a central port or use the port as the baffle between the 2 chambers

[carshateme]

Well I wanted to do center ones but I couldn't decide rather to do a center split or not.

Hi carshateme

Can you tell me how you modeled the first design. It seems to me to have two different cavity volumes for each port. What frequency are you attempting to tune the ports to.

Cheers PJC

Did you design the box based on the driver's T/S parameters or just make up a box? Why did you make the cross sectional area of the port larger near the back? What F3 point did you need for this design?

Edit: Looks like Max Caliber and I posted at the same time, but with the pertinent questions.

[carshateme]

I honestly did the box by volume base. I put the back port by 4in and the front port by 2in. I'm putting in a 2in on both top n bottom in the back. Making the port 7.5in...I honestly don't pay attention to frequency. I don't know how to. So I pay attention to the volume. I may just pull the back part 2in forward.

[TheBaronGroog]

Give me the outer dimensions to the volume your box can take up, the thickness of MDF you'll use and the T/S for the sub and I'll model some for you.

If for music I'll tune to 35Hz (thereabouts)
For just SPL I'll tune to around 70Hz

[carshateme]

If you can do it for two models one for. 75mdf thickness and one 1mdf thickness thatd be awesome. Had trouble w my last. 75 mdf board...wood kept splitting



Well I'm going w 1" mdf board...dimension on outside is 33" x 13.5" x 26" total volume needed is 1.5... after speaker displacement it'd be 1.35 because the sub displacement itself is .15. if you could scrap ofc a few inches in the back it would be awesome. Originally the.dimenison was 33" x 13.5" x 23"...but the ports got in the way. The sub box is just needed for an everyday box. I just want something that people can hear a mile down the rd and sealed box just keeps all the bass inside my car.

[TheBaronGroog]

Are you pre-drilling the holes before you screw? MDF will split if drilled straight into, sometimes even if you have pre-drilled.

So you want "streetbass" I'll tune low for you-what music are you playing on it?

[carshateme]

I pre drill everything, but I think I used drywall screws on my last box...if not...they were awfully big for the .75 mdf board..but the splitting issues were only at the end of the box...and gorilla glue fixed the problem with no issues...but it could've been because I drilled to close to the end.


I listen to rap/techno/and dubstep.
