Hello from Finland

I'm 48 years old steel factory worker from Finland. I always prefer to do things by my own hands, when I can reason it somehow (usually getting better or better suiting or unique product for the same price, or preferably even save some money). I have pretty modest set of tools and I don't understand electronics, but I get things done. I don't like to use too much time for thinking and hesitation, I just need get to work. With that said, I'm here because I would love to build my own Genelec 8020 "killers", but as cheaply as possible (for home theatre and music), and perhaps with a subwoofer. My wife loves how those white speakers look.

And then I would also love to have something between 8010-8020 as my "home studio" computer speakers.
