Pardon the length of this- I am very new to all the acronyms and specs required to build a home theater sub but I am a fan of what they do and a semi accomplished carpenter. I have a Def Tech Supercube II that has some internal issues that I don't care to have fixed. So the parts I have are: 1-8" driver from said subwoofer, 2-8" passive radiators and as it happens I also have an 8" driver from a Supercube. I would like to use what I have and buy a plate amplifier. The primary use of the sub will be home theater. I am open to varying deigns but am not into researching/learning a whole new language. Any help would be very much appreciated and I will upload photos of my project. If it matters my room is 14'x16' and I am married so the size can't be overwhelming, LOL.
