Actually, I’m planning to build my own speakers using the drivers I used in my car. Since the drivers are not the high-end quality and was mainly designed for use in car, I’m not sure If all the work would be worth it.
On the other side, there is a 3 way speaker designed by professionals. The price would be higher, but the quality of the sound would be much higher as well.
