box build for T1D2 12" Pros & Cons (edited dimentions)

[bcbrassard]

I built this box a year ago and since then my knowledge has grown and was looking for opinions & suggestions on what i did right or wrong. And what i can do to improve current set up with areo ports if need be.

Box dimentions: (inside box dimentions)

36.5" W x 14.5" H x 10.5" D = 3.116929 Cu ft

RF T1D2 12" displacement =.308 Cu ft

Box after speaker = 2.808 cu'

Ok i wanted it to look cemetrical and centered the sub w/ areo ports on either side(bad idea looking back now)

Areo ports cut to 9.85" for a tuning of 42Hz but there is only 2" of space between the back of enclosure to end of flared port inside.

Question: is that enough room for proper firing & loading? The box sounds good, but i dont have anything else to compare it to so i dont know if it would sound better in a different set up or design.

Any input is appreciated. Considering rebuild box this summer. Adding another T1D2 12" and doing a blow thru from rear deck into cab.

Sub in 1 ohm being powered off a RF Power bd1000a1, Thankjs for any help, heres a pic if that helps.

Okay I haven't finished reading yet, but already notice something.

The cubic feet gross of the box is actually 2.37.

I'll edit in if I see anything more.

Edit:
Assuming those are 4 inch aero's 9 inches long each, that brings your tuning to ~49hz.

Net volume comes out to ~2.1 cubes. Which is okay for that woofer. But the tuning is pretty damn high. I'd drop it down to like ~35 or so. You may have to go with a slot so you can bend the port easily for the necessary port length you'll need to achieve that tuning.

Here's a new box using the same dimensions that would most likely sound a lot better

My bad math, your probly right. Thanks!

OK, thanks for the info, new box build sounds like the fix then.

Fixed mistake on info, whats anyones thought on changing these ports out to 6" until i can build a new box this spring.

Okay let me put together something new. Hang tight.

6" aeros would need to be significantly longer just to get the same tuning and you need to tune lower which would make them even longer. I don't think you will be able to fit them in the box. Time for a whole new box unfortunately.

I really suggest doing a slot port. Shorted the depth because I figured you have a specific width and height that you prefer.

Thank you for your input, i guess new box time. Thats cool though, give me something to build this spring, I wonder if i have enough room to do 2 T1s in a blow thru into the cab.

Thank you for the box design and your help. Much appreciated.
