Default upgrading cheap speakers

Hi everyone- I am a first timer. I have been experimenting with audio equipment recently. I started by making a speaker with 2 two cds sandwiching a voice coil with a neodymium magnet. It worked great, but I couldn't figure out the voice coil wire and the speaker kept overheating.

So, now on my college budget, I bought a cheap set of Pioneer speakers. I am wondering what I can do to easily modify them for better sound quality. The cd speaker I built sounded better than these do. I have a sub, 4 satellites, and a center speaker. All with 3" drivers. I am very disappointed with the sound, but what can you do with very little money. The mid-ranges are muffled.

I took one of the drivers and put it in a cherry wood box with a super shammy in the back. That seemed to help, but I want to take it about 10 steps farther with new boxes and modifications. I don't know where to start! Any input?

If the 3" drivers are poor replace them with something decent.
Then take it from there with BSC and correcting notch filters.

See the loads of threads on the B3S, NS3 and W3871.
