Default Opinions wanted on enclosure

This will be the first ported box I've built so I just want to make sure I've got this right. The subs will be 2 10" AQ SDC2.5's they recommend 1.2-1.5 cu ft per and tuned to 34-38hz (I'm going for 35/36hz at 3 cubes) I used RE Calculator to get an idea of what I'd want and then took it to SketchUp to see it better. Here are screenshots.




The braces are 1"x1", the port wall ends 3.75" from the back wall, and the corner piece is 3.75" from the corner of the port wall.

Basically does everything look good to you guys? Bracing good? Port good?

Honestly think there is too much bracing. Kick off the bracing that goes behind the subs, and in all honesty you dont have to have any bracing with the woofers/power you're going to be running.

Other than that all I see that could be an issue is the fact that your port is around 5" too short...

Maybe I shoudl clarify - I meant in your drawing it was wrong, it is supposed to have a bend in it due to the length.

According to Car Audio Classifieds my port length is 22.25 and that's only .6 off of the RE Calculator?
Maybe I'm confused on why I need to add 5" to the length, if you could explain I'd appreciate it.

Thanks for the tip on the bracing though, I couldn't find much info on it. Just read somewhere that its recommended for 3 cu ft and bigger so I threw it in there.

Like I said the bracing isnt necessary. Would it hurt? No, not really, I just wouldnt put it directly behind the sub(pet peeve, I guess?)

What I was talking about was your picture. The length at 22.25 is correct, but in the picture it doesnt curve and it has to take a turn to achieve 22.25", if that makes sense.

This is where I am confused then, this is from that guide. (I know this one has an L but I figured the same applied without)


When I do that it says 22.25".
So I guess is that right or am I suppose to make the total length of the pieces of wood making the port 22.25"

Yes, you will have an "L" like that and extend the port to a total of 22.25"

yea as far as bracing, and that 45 in the corner goes, i would test just straight box first and then add each mod to the inside of box to see what it does to tuning etc., don't wanna have too many variables at once. granted i am like 15 jager bombs deep and probably shouldn't be giving advice....lol and i also don't know if you have access to a tl mic or if your even going for any kind of numbers just some nice daily beat
