In the first house, we installed Stealth 2 ways (FX8?) with backboxes. Like I said, sound is only OK. If I had to do over, I would have forced the issue of bookshelf speakers hidden in the bookshelves (my original design idea).

Actually, in the modern house, we installed 4 Triad invisibles (DS500?) and they sound great. Not as easy to install as the Stealths, but they sound a lot better.

In any event, my experience with all invisibles (going back to B.E.S.T. in the 80s) is only so-so. I am on a mission this year to try to deliver better sound and simpler systems if I can.
