  • 2.1 with W6-1139sif and nd91-8

    A while ago I made a 2.1 set with the w5-1138smf and 4 nd65-8.

    ​​​​​http://techtalk.parts-express.com/fo...iginta-sub-2-1

    It sound good to me but a little bit thin and with music with low bass a bit to overwhelming ( maybe because of roomgain.


    Now I read about roomgain they said 565/L where L is the longest dimension of the room in feet, so in my case 565/18,8 feet = 30,05 hz. I also read that roomgain is +6db octave. I have a mobile app where you can add roomgain so I simulated this box for the w6-1139sif. 16.5 L tuned to 23 hz.

      The amp I use is the same as the first project and is the lepai Lp210pa or actually a cheaper one( 20$) with this project. Both seem to his at the left channel so loud that you can hear it tru the music. I have tried a few things, use another rca cable, use another power source and at last used an other phone wich seem to be the right thing because I don't hear anything anymore even with the music off.

          Add another(third) layer for the slot port, 1 last piece to attach later. Cut a hole in the back for the amp, wich I make sealed because in an other design there was to much noise coming "tru?" the amp. I also cut a hole in the front for the subwoofer and make a flared round over(don't know how to say in English). Because the sub is attached inside the enclosure I gonna paint the front baffle before I put the speaker in the enclosure.

              That is quite a port! Where is the port opening going to be?
              What are the port dimensions?

                The port is going to be on the front but I still have to make a opening.

                The port is 20.3 cm x 1.8 cm without the slats and must have been 120 cm but is 126 cm. Doesn't make any real difference.
