Default some samples box very good for full-range speaker

Hi everyone, I have designed some samples box very good for full-range speakers. Today I will share for everyone to do.
Its advantages are:
- Improved a lot of bass range. You can hear bass range 35-40 Hz
- Keep the natural and real of sound.
- Reduce the sound um um, om om, sometime you can hear in box BLH.
- Neat, simple, can be done in just one week.
I'm sorry, because I speaks English no good, but I can use many pictures.

You can be seen range trebl Nirvana better, but the range Bass of Philips

I'm sorry, I am new member, I can not post, because administrators need to check
you can hear bass range if you have headphone good.
