[ali_moinuddin]

Hello friends,

I am Obsessedwith the performance of philips wubwoofer philips-hts3400.

I wish if someone can help me with the internal design of the Box.

The driver seems to be a 5 inch woofer.

(note: please see the attached picture)


IF i can get some idea with the internal structure fo the box that wil be a little help for me to start with.


the length of the plastic hollow pipe which is present on the front of the box .

IS the box have a isolated chamber if yes how is it connected with the ported chamber.

hmmm

That is not a ported enclosure, it's a 4th Order Bandpass.
