In wikipedia woofer manual has limit is between 40 hz to kilohertz here it is different.

Mostly songs have Frequency under 100 HZ. So low pass filter is the perfect fit.

You are giving band limit for particular range why can't band pass is not correct?

The woofer is for larger sounds it should attenuate Lower signal why not it is high pass?

Low frequency components are integral part of live sound for most modern music. So, I/p to woofers are fed through an LPF to justify and allow low-frequency components to pass i.e preserve the music quality. Woofers along with LPF are also fitted with HPF.
