I believe your correct and it would be nice if the combo they sold was a 24V setup instead of the 12V supply......220W per channel for 400+ dollars kills it for me but if it came with the 24V supply and could do 400 per channel then it would of been much more appealing to me. I feel like the setup as a whole while neat looking is bigger then it needs to be as well from a couple video's I watched.
