Hey guys need a little help with box design ( more visualizing a concept if anybodys got time to draw something up in sketchup for me )

Got 4 10"s Memphis M3s

The max trunk space I have in my 1995 2dr Civic EX is 33w x 14.75h x 25d comes out to i think 5.3cf which might be a tad tight, but I should be able to fit it. ( dont wanna build the box in the car )

Want a ported box, with all subs facing up - not sure which way to port it whether the port should be up facing or forward towards the back of the car or towards the cabin? ( what do you guys think? )

Here is some images of the information sheets I got from memphis..

First one is all the specs of the sub - mine is the second column M3104D

Second one is what they told em for enclosure recommendations ( they sent me a huge PDF for bout 20 subs, so I just screenshotted and copy/pasted what I need and made my own image ) I think the Optional tab is their form of recommended.

And the third one is just some calculations I made with Torres Calc not 100% right specs but somewhere in the ballpark.

Anyways, to sum it up, what do you guys think would be best for the port firing direction?

And - Anybody wanna draw me up a sketchup :D free if possible..

you have virtually no port area man. deff need to bring that up to at least above 12 sq inches per foot if using a slot port

I am on my MacBook Pro right now, so I dont have access to the Torres calc.

Maybe you could do it for me :good:

Since I completely overlooked that in my design..guess I was just paying attention to the tuning more than the hz

With my dimensions it is kinda hard though...since I havn't built too many boxes.

i know a guy who goes by skip01 that has a design for 4 tens that would be applicable in your case i think. the design im talking about is shown in this vid.

as for your specific dimensions, i used 14H x 30W x 25D, 1 6" aero port 13" long, and a driver displacement of .25 cubic feet. just as an idea...

You're going to need quite a bit more port. I'd try for around 85 inches of port I think. Try bumping your port width to 3 and extendig your port lenth to around 32.

:shrug: Widened it to 3" and extended it to 32" and it dropped my tuning to 26hz and Net Volume to 3.96 anddd only gave me a port area of 39in^2

I dont know what I am doing...maybe demanding too much out of the little space I got?

I just kinda figured since they want 2.4cf for 2 subs ported after displacement. It would be a doable, but tight fit

Once again : :shrug:

I would change the port width to 4 and the length to 20, have the port facing the rear. Would give you a 35.17hz tuning which is still pretty low i would say, and a port area of 52 and 12.83 per ft.

GOD DAMN that shit looks like it slammin :( I am pretty sure I could get pretty close to that off these though...Hell they sound good in the ported box I built for em. But I'd like to see how they do in ported :D

I put in those dimensions. And liked it. Port facing the rear or cabin?

Sounds good... How do you think that would stack against the dimensions/port on the other post I quoted? Just wondering, cuz I was messing with it and came to a conclusion that a slot port was out of the question. But I wanna go with what will be the best :shrug: I really like that video though... but his is ported towards the cabin.

Any special reason why u say toward rear?

Hmmm...

I wanna ask for someone to draw me something in sketchup - but I dont want them to be wasting their time and effort if I dont know whether to go slot or ported.... Gonna make a poll after I post this...first to 10 wins. LOL
