I finished assembling the second speaker last night
They still need to break in, but they sound really nice. Very full bass, and clear highs. I'm quite happy with them. All told, with extra stuff I bought to finish them, I'm probably in to them for $450. It was a nice little project that I could spend a few evenings on with my kid.
My wife wife wants me to paint them black, but I'm going to have to see if I want to paint the MDF or add a veneer.
I hate that entertainment center, btw. And pay no attention to that (off-)center channel speaker, it's not being used. And before you ask, yes, that is a laserdisc player.
