I want to build a new box. Sub up, port back.
I want to have it 4 cu.ft and tuned to 40. I want to use aeros one this box.
Many people have told me that my box right now is tuned around 34 for it and i'm pretty sure it'll like 40 more.
The port right now is up against the back of the rear door so I was hoping to have my new box a few inches away from it(if it'll make a difference).
I was hoping someone will have a free one they already made up. But if not, let me know and i'll pay a few bucks.
The max space i'm working with.
Depth - 24"
Width - 30"
Height - Around 20"

BTW, I did search, everywhere, including google......came up with nothing.

Forgot to put the power I have.
I have a good 2000 watts to put on it. But doubt i'll use all of that.

I say go to http://reaudio.com/speaker_box/LPort_Box_Calc.html and enter in your dimensions, and mess around with them until you get as close to your specs as you can. I'd say try and keep your port area to around 60 sqin.
Good luck,
Larson

why not shorten the port first to see how you like the higher tuning?

Aluminum or Copper coils? If you've got the aluminum coils, you could use more of that 2000 watts and go for a smaller enclosure for more power handling. Should sound nice and tight and still get loud. Also, why do you want to tune so high? Is this for SPL purposes only? I wouldn't tune to 40 if you want to listen to any music. Highest I would ever go for a daily is 37-38 unless you're talking 4th order bandpass.

copper will b able to handle that power as well.

Can't shorten it. It is built like a tank, there's no way of opening it. It's a slot port right now.

It's copper coils. They'll handle 2000 just fine after I upgrade more of my electrical(new alt on the way).
The HDC3 like to be tuned between 38-40, just ask DJ. It's for daily use.

Will a 15" work in a 3 cu.ft. box? A 12 would be better for that size.

Thanks.

a 15 "Can" work if you have a TON of power, but i wouldnt do it unless i was burping.



then again we put a MT 18 in a 3.7 and it sounded really good.

remove the sub and figure out how to cut the port shorter, you'll raise tuning and gain some box volume.

vehicle dependant if you want "best" you have to build a few boxes and test them out...
