Build a subwoofer with your own hands!

Next week I devoted to the calculation of the subwoofer. I downloaded several programs for calculating the subwoofer enclosures (DLSBox2000, JBL-Speakershop, WinISD ...) Most of all I liked the DLSBox2000 program. With her help and calculated sub. And that's what happened - the effectiveness of this design (FI) for my speaker is 76%, volume - 37 lire (external dimensions 45h35h35sm.), Bass reflex 75x100mm. (diameter / length). Then he drew a sketch on paper, and began making it.

All walls were tied with 50mm long screws. All connections are planted on PVA glue (advice - no need to spare the glue, it will squeeze out too much). Inside for greater reliability, the seams missed with silicone sealant. In principle, this is not necessary, but it is better to miss the mark and forget than to disassemble again.

Then proceeded to putty. Shpaklevku used car, two-component (You can make the putty yourself, mixing small wood shavings and PVA glue, as an option).When the putty has dried, I polished the body almost to a perfect plane.

Then cut the holes under the phase inverter, the socket, under the handle-pockets.

Putting together a subwoofer to see how it sounds.

All my doubts about the correct calculation of the volume of the box in a moment were dispelled - the self-made subwoofer played a soft even bass. Making sure that nothing whistles anywhere, I took off the "hardware" and proceeded to pasting the case with a self-adhesive paper with the texture of the skin. Collected.
