Box for 2 XL m2 12s

[LosIsATool 5,000+ posts]

Im going for 3.5 internal after displacement. I have 6 inches I can use for port height, if shorter is better thats fine, External slot port wrapping up the back side of the box and extending out the top firing rear. What length and width do I need for 1 port tuned to 32hz. I have a little something in paypal i can send for a good solid answer. I want output and lows. A hairtrick port, with decent numbers.

I only have a few days to plan this out. The shop I use has a opening Tuesday so i got the spot. They are top notch installers that will do whatever I advise. I do hope Buck, rabbit, or Ram chimes in

For sure. Well either one of them can for sure help with design.

I want to see if this will work.

Can somebody tell me how many sq inches of port this is? 3.5 internal after displacement: 12 inches wide, 3 inches tall, 30.4 inches long slot.

36sq in of port opening and 10.28 sq/in per 1 cube of airspace...... WAY too small!! Shoot for 50-56sq in (14-16sq in per cube) of port area. This will require the port to be longer as well. The port size and length you just listed has a tune of about 28hz btw.

I concur for this situation.

If you can get me t/s parameters I'll tell you what I would do.

The best I can do is 13.7sq per cube

That should be fine.

What are your outer dimensions that you are working with?

 

[LosIsATool 5,000+ posts]

That comes out to a slot: 16 inches wide, 3 inches tall, and 35.34 inches long. That should move air

I dont really have them yet. Its pretty much unlimited for this application. the port has been kicking my ***. It was the worst part about my last box

So then why is your port limited?
