Please Give me some advice on Speakers

I would recommend that you head into a specialty shop, these professionals are the people who solve this kind of problem on a daily basis, they can also provide a wider range of products available to you. To choose your speakers based on a spec or what a book or net reference says will fit is just plain wrong. You should choose the speakers that you know will fit (confirmed at the specialty shop). You should choose the speakers that will do what you need them to, handle what you want to throw at them and sound how you like them, the latter is the most important, you must listen to the speakers you choose to see how they sound.Top Secret, I can tell you but then my wife will kill me.
