Hey every one I have jbl 2226h pair want to make subwoofer one jbl 2226h in one box need best box dimension have crown k2 power My room is 13w 16l 8h Thanks
Put them in a 10ft3 box tuned to 40Hz with plenty of duct area. An example would be two 6" diameter ports, each 5" long or four 4" diameter ports, each 5-1/2" long. Brace the cabinet well.

Can u plzz tell me the 10cubic feet dimension in inches and how low it will go thanks
Yes, put a pair of 2226 drivers in a 10ft3 box. Dimensions aren't critical, provided it's a rectangular box with no single dimension extremely long. I'm not concerened about internal standing waves above 100Hz because it's a subwoofer, so you'll low-pass it.
Want dual separate subwoofer Read jbl pdf they recomended for a single 4 cubic feet tune to 40hz On some internet search some are recommended 5 cubic Feet i just want is musical
If you want a subwoofer cabinet for a single JBL 2226H, then make a 5ft3 box tuned to 40Hz.
I m total noob with diy thing its my first diy sub Can u plzz tell me 5cubic feet box dimension in inches whit ports in inches thank
Make the box 35" wide x 22" tall x 13" deep. Use two 4" diameter ports that are 5-1/2" long. Use 3/4" or 18mm Baltic Birch or MDF. Brace well using cross-braces (front-to-back and side-to-side) on each side of the woofer along the 35" dimension. The braces can be made using scrap cut from the panels.
One last question Jbl recomended 4 cubic feet box with tune to 40hz is there any advantage on 5 cubic feet box
More bass, about 3dB more at 40Hz.

That's the same box dimensions I gave you. It doesn't matter how the box is oriented.

The dimension 35wx22tallx13deep is inner volume ?? And i also can use these dimensions too 30 wide 20 tall 20 deep ?? m i right
The (35" x 22" x 13") dimensions I gave you were inside dimensions. My dimensions create a box with 5.7ft3 internal volume. The additional size makes up for displacement from the parts inside. Your (30" x 20" x 20") dimensions make a box with larger internal volume, 7ft3 to be precise. That 2ft3 is more than would be displaced by the parts. You could go with (30" x 19" x 17"). That's pretty close to the volume of my original dimensions. It doesn't have to be exact. Thermal changes at various power levels make more difference than a small volume or tuning change in the box. But still, try to keep it within +/- 10% of 5ft3. Otherwise, you should modify the ports accordingly.

Well boxex are under working W8ing for ports Tell me in square shape so its easy we will make here Or pvc pipe 3.1/2" is also laying around
You can make two ports, each that are 3-1/2" square and 5-1/2" long. Dimensions are internal. Length is from the front of the baffle panel to the termination inside.
