I have very little knowlegde of what a speaker is and how it works......-I have a horn speaker 80w 3 woofers and 2 tweeters everything is 80watts , I wish to make a speaker of 200 watts, - do I have the right stuff to make it !
Do you full speakers or just drivers? If its just drivers you will need to set up crossovers for which you'll need capacitors, coils. You will also need resistors, magnets...
Either way, if you dont know what you are doing...even if you DO know what you are doing, most likely your speaker will sound crappy compared to a flagship manufacturer. They spend a lot more money on research and tuning before taking a few random parts and putting them together.
