  • Mini vented subwoofer using W5-1138SMF + diy plate amp

    I made this little 100w subwoofer using the popular Tang Band W5-1138SMF.
    The plate amplifier consists of a Wondom/Sure 100w subwoofer amplifier, a 24v power supply and a little preamp module.

    I am very happy with it, and it puts our a suprising amount of bass.
    Only thing I'd like to change is the crossover point. The amplifier has an adjustable crossover point down to 200Hz, and I would really like to turn it down to 150Hz or 120Hz.
    For now it is a great addition to my complete diy setup and I plan on winding my own coils in the future, so this will be a great oppertunity to experiment with that.

    Hey Hofman, what "little preamp module" did you use for this project?

      It's a preamp module based around the NE5532 chip.
      I got it off Aliexpress

        I understand about PE's "other vendor rule". Can you message me with the particulars? Much appreciated...
