I disagree. I'm still kind of a noob (been on here for a lil while and have learned A LOT!) and I'm going to be building myself my own system (similar setup with sub, 2 tweets and 2 mids) for my own room. The kind of amps your are going to be looking for are plate amps (for your woofer) and Class T amps for your mids and highs. I suggest using a pair of coaxial speakers for your mids and highs so that will minimize the amount of wiring you will have to do. As for components, what you use all depends on how big your room is. If you give me dimensions, I can point you in the right direction.
