Quad DC Level 4 15" Bandpass Box

[RAM_Designs 25]

This is for Justin Willmon at the *****.com forum. Four DC Sound Lab Level 4 15's will be going in here. Each sealed section is 3.6ft^3, and the ported section is 11.5ft^3 with a 47hz tuning. This is going in the bed of a single cab Dodge 1/2 ton truck.

My cpu restarted on me and I lost all of my open tabs and designs...thankfully everything was done and I got all the pics I needed.

Looks Awesome Ryan ...

nice how big is the port

[sefugi 166]

nice how big is the port

30 X 7.5

Looks Loud!

[RAM_Designs 25]

30"x7.5", roughly half the cone area of the subs.

how are you measuring cone area?

how are you measuring cone area?

Somewhat rudimentary you can just use the formula Pi(r^2). example: 10" subwoofer, radius is 5", 5^2 = 25", Pi(25) = ~78.53in^2

Or you could look in the T/S specs and look for sd (effective cone area)

[RAM_Designs 25]

I used the sd listed on the DC website.

I didn't see any way to interpret your question differently, but at the same time I was surprised if someone didn't know how to find the area of a circle.

lol. so rudimentary. let me rephrase my question for morons. did you use Pi x r squared or SD?

Design is sick Ram, I really need to learn sketchup

[stealth 113]

lol. he posted after you. thats the answer i was looking for. Not "Circles For Dummies"

if im a noob then why did you mention pi r squared. lolimus maximus this guys a moron.

Looks good as always ram!

Looks good as always ram!

Thanks!

No need to slander other members. If you feel the need talk trash go somewhere else, willingly or not, your choice.

Enclosure looks good Ryan, it should perform very well

[RAM_Designs 25]

Thanks Duran. Here's a pic in case anyone's too lazy to watch the vid.

Actually a little more than the area of a circle since it is a cone.

This enclosure is going to be nuts
