Simple steps to make your own 3 way tower speakers
The Design: First of all decide how you want your speakers to look like. Search for Tower speakers on Google images and you can see a lot of speaker units. Identify the one you feel you can make.

The Box/Cabinet:The speaker box or cabinet design brings out the best in your drivers. 70% of the sound quality that you get is because of the box. I used an old computer table made of MDF. It was destroyed when relocating. I made the rectangular box with basic measurements and joined all the sides except the front panel. The inner edges i sealed with M seal so that its air tight. You can also use wood sealant paste. The front panel i got it cut based on the dimensions of the drivers.
Partitions: The inner partitions are pieces made of the same MDF and I arranged it in such a way that the air passes through one chamber and comes out through the other and finally through the port. I used a PVC pipe for the port.
The partitions are fixed as shown in the image and again the edges are sealed to prevent air leakage. You don't fix the front panel yet as you need to dampen the inner sides of the speaker wall for better sound effect. For this i used an old carpet and stuck it all around the inner side of the speaker and used glass wool for the rear side of the speaker wall.
CrossOver Network: Below is the image of a cross over network. You can get a cross over-network from your local market. You can get very good CO networks but i have used a very basic one.

1. IN- you connect the positive line from your amplifier to the IN of the board. ( The positive is marked with red color)
2. COM- you connect the negative or the black lead coming from your amplifier to the COM of the cross over network.
3. W- Stands for woofer, you connect the positive of your woofer to the W of the board and the negative of your woofer goes to the COM on the board.
4. M- you connect the positive of your mid range speaker/woofer to the COM of the board and the negative to the COM of the board.
5. T- stands for tweeter, you connect the positive of your tweeter to the T on the board and the negative goes to the COM on the board.
