Home Theater Bass Box Design

[swavvv]

Hi,

I need a home theater bass box for 6 1/2 " & 8" Subwoofer 60W. any one can Help me.

As I said on the other website, a little 6.5" or 8" woofer is too small to produce the very low frequencies (down to 20Hz to 25Hz) of a sub-woofer.
You posted the spec's of a little 6.5" woofer that makes boom-boom sounds at 200Hz. I have 6.5" woofers that are flat down to 52Hz. With some bass-boost they go down to about 35Hz.
Didn't you see the fairly inexpensive 10" REAL sub-woofer with good spec's and enclosure designs that I posted?

Different box shapes and different types of boxes.

You can try with these dimensions.

He is not on another website. He has TWO threads about this little woofer here and the first thread is: https://www.edaboard.com/threads/301456/
The cheap little woofer that has a peak in its output at 200Hz and a resonance of 52Hz is linked in post #16 on the other thread.

There is NO WAY the cheap little woofer can sound like a REAL sub-woofer.

i have one more Question, can i use this type box( http://obrazki.elektroda.pl/3410931200_1390114378.jpg ), sub-woofer at a bottom, if this we use, then what is its dimensions required.?

 

[Audioguru]

If the dimensions are huge then the little 6.5" woofer will go down to about 50Hz in the type of ported enclosure in your photo. Then one entire octave of sub-woofer sounds will be missing.
The enclosure in post #5 has such a tiny sealed box (0.3 cubic feet) at the rear of the speaker that it will have a peak at about 120Hz then roll off at lower frequencies. No bass.
