Hello, I hear rock and I want to buy a sub. With the case I don’t know exactly now, best I build it myself, or buy it individually. Because if you buy the chassis individually it’s better with the choice and so, right? So the chassis should cost between 100 and 150 euros. Do not need to go too deep, but it has to be fast. For rock (metallica rammstein and co). Which should I look at or maybe listen to better. MfG. oh yes: Hu is a blue point and amp is a Next Q24. FS becomes a 16er compo for about 150. From Rainbow or something, I still don’t know…
