EDIT: It will also be ran off a brz.1700 and an upgrade to a crescendo bc2000 when more funds come in. It's all going into a dodge charger.....If that helps.

looks good, that's a great calculator. wish i had that when i did my first box.

what are you tuning it to?

[tlh_360]

It says 35.04hz 2.99ft^3 and 16.56in^2 of port area

You'll need to double up the front so tick baffle in Torres

You'll need bracing as well so that will be around 0.02-0.03cuft (3/4 or 1" round bar)

Put a 45's in the the port and opposed side to port(not needed on front as double baffled but you can still put)

Other that port is all good at 16-17sq" per ft port

And power that with 15-1800rms and you'll be fine, if you want 2k+ drop the net to 2.5net 19sq" per ft port

[john253a]

Also tune it to 33-34 and you'll be a bit happier unless you chasing a bit more spl then 36-37hz

Alright I'll mock it up when I get home later today. Should I put a round brace between the rear port wall and the back wall of the box? I think in just gunna build the 2.5 box now that way I don't have to build two boxes. Would the 2.5ft^3 with 19sq" of port be alright with only 1700 rms?

Don't think that brace is necessary, but if you really want to do some bracing. a bit larger 45 on the port walls would do a good job without interfering the port airflow.

Ok it took some crunching lol but how is this.

SPECS:

BOX:

What do you think. The only thing I can think of is only having 4" between end of port and the side wall. Will that be ok since its larger than the 3" port width? Also I dont know how to do 45's on sketchup but I figured there would be 3-4. 2, 45's along the back two corners(in port area), 1 right behind the sub, and maybe 1 on the front wall( right of the sub cut out) depending on what you guys think.

EDIT: This box is 2.53 cubes, 34.40 hz, and 18.99 sq". It's kinda small to read.

Also the brace is 1" round.

Make the brace closer to the sub cutout, and do a vertical one as well to brace the top/bottom of the box. There are 1.25" dowels at Home Depot.
