1. ## is this tuned right ??

acording to me this box is tuned to 35 hz....what you think ??

2. ## Re: is this tuned right ??

depends on the ungiven side of the second port piece.

If the second port piece is about 13ish inches long then your at 35 an this is all w/o sub displacement at 5.8cuft

3. ## Re: is this tuned right ??

actually the port is 18.53'' and the box with out displacements is 8.9 cubes....so the port displacement is 1.34 cubes and the sub displacement 0.26 cubes...(fi btl 18'') so the box would be 7.4 after all displacements right ??

4. ## Re: is this tuned right ??

3/4 Inch wood?

5. ## Re: is this tuned right ??

This was VERY quick math, so I would appreciate if someone checked it for me.

But I got...

4.6 cubic Feet
126"^2 of port area
27.53" of port lenght after end correction.

Tuning Freq=44hz.

6. ## Re: is this tuned right ??

scratch my math...already found a mistake. Im working on it.

7. ## Re: is this tuned right ??

6.9 cubes
126"^2 of port
27.5" of port (after end correction)

Tuning=36hz

next time try and make the drawing a little more detailed , and a little closer up, had to really look to get some of those dimisions.

8. ## Re: is this tuned right ??

yea it is 3/4 mdf...double bafle too..

so ?? what you think...this is tuned to

9. ## Re: is this tuned right ??

bump..need some help here...

10. ## Re: is this tuned right ??

Why in the hell would you put double stacked 3/4" strips at the end of the port wall?

That's awesome.

11. ## Re: is this tuned right ??

6.35ft^3 net volume tuned to 35.98hz.

Not taking sub displacement in to calculation...

12. ## Re: is this tuned right ??

you sure it is 6.3 ft3 bro ?? accordin to my maths it is 7.7after port displacement....lets see...

internal measurements...

21x21x35 = 8.9 ft3

port displacement 6x21x16.5 =1.20 ft3

so 8.9- 1.20 = 7.7 ft3 after port displacemen right ??

or let me know what im wrong please...

thank you bro

PM sent with corrected figures for most recent box posted.

14. ## Re: is this tuned right ??

Redline should be your port length dimensions...

15. ## Re: is this tuned right ??

I came up with 37
