Parts Express is a good source for building speakers.

Conclusion:

These were made with pure enthusiasm. It didn’t save time or money to make my own tweeters. Many hours and into years of testing were needed before matching store bought quality, but after a while they can compare or go beyond.

About the Designer:

50 years ago I made my first crude weak speaker for a 5th grade science project out of a shoe box, paper bag, and toy motor magnets & wire, using a transistor radio for the amp.
The science teacher gave me a “D” because I didn’t make an electromagnet winding wire around a nail.
Been making speakers on and off ever since.
