If you don't mind. Why don't you get a speaker building book, software, audio magazines, etc... and do your own research. Start by building your own projects. Take time and learn the hobby. Invest time and money and then you will know for sure.
I don't mean to be a hard-a$$, but thats the beauty of it all. Get some dirt on your hands and learn the old fashioned way. Then you will have respect for it, and you will appreciate it.
Sorry folks, but there are too many whynos that want the best, but they don't want to do the hard work. Give me a break, I can see Phony written all over your face.
