If you are looking for a loud clean sound as close to having components with out actually having components these are the speakers for you. They come with a true crossover so the woofer and the two tweeters are on separate voice coils. Easy to install comes with everything you need.

I have these in the back of my car in an infinite enclosure. Because of the enclosure type I run them from 120 Hz. They indeed easily can take 75W and the sound quality is very good.
