Those are speakers with no audio source, so the price comparison doesn't work.
Also, there is no way my wife would put up with those things in our living room.
This is not a fair comparison at all because you haven’t put any opportunity costs into your calculation.
How long did it take you to build and modify those speakers?
I can imagine they sound nice and since I work in a studio I’ve seen many speakers with funny designs and outstanding sound but to be honest those look like an ikea lamp from the 90ies..
