25" wide
13" high
10" top depth
13" botttom depth

Port is about 8" high and 1" width with a 8" depth.

the sub is on the flat side of the box, i measured it out and getting about 1.4 cubic foot inside but how much space would the back of the type r subwoofer take? its sounding aweful at full blast so i think something is wrong??

i used this site to measure the box http://www.reaudio.com/speaker_box/LPort_Box_Calc.html
but its wrong they have the port on the slanted side.. but my port sits on the flat side.. could effect the tune and it would not be 37 like it said?

yeah thats too small. did you follow any plans? that seems like a really small port. type r's sound really nice at 2-2.5cubes at around 32-36hz tuning.

hey guys i got a question, since the box is tuned to 37 should i tune my amp to 37? theres these 2 little nobs on the amp that adjust from 40-240 or something like that..

also any recommendations on what i could do with this box to make sound improve?

No do not adjust your amp to 37. the adjustment on your amp is basicly a bass cut off point. If you adjust it to 37 you will not get any frequency above that point. I and just about everyone else adjust their amp to 80.

yea just get someone on here to draw you up some plans and then you build it.
