Well, as per the OP...
For all the details regarding build quality, specifics on the 20’s performance, and design take a look at the review.Incidentally, teajay bought the review samples after reviewing them for The Stereo Times, which I highly doubt he would’ve done if they were made from “$100 worth of junk.” While I understand your concerns, I don’t think there’s much to worry about with these new LSA speakers. FWIW.
