Okay, I'll go there.
Let's do it this way, say you want to build it yourself, that's cool and there is nothing wrong in the least with that, compile a parts list shall we?

I left out things like, nails, glues, paint, sealers, and labor for anything. If I missed something let me know. Now, @ $799.99 that leaves a whopping $261.99. If I were to use all of these ingredients, which I dont because they aren't one of a kind( they're vacuum infused). What is your time worth, and add those figures. Some are the fabricating types and love building the one of a kind enclosures...and I applaud them!! I am one too. But some don't have the time or skills, or energy. Sound is subjective and if we all used the same speakers what choice is there?
Sorry this was so long, but lets look at reality.
