Just when you thought nothing else
on this planet could ever earn THX certification
, here comes Serious Materials to prove you wrong. The image you are inevitably peering at above is the world's first THX-certified soundproof door, the QuietHome. Boasting an STC rating of 51 in a 2.25-inch thick door, it's said to be the only door in the world to stand up to those mighty THX standards. Just for reference, it's noted that typical hollow-core doors have an STC rating of only 15 (and solid-core doors around 27), and we're told that this one will reduce noise between 65% and 85% compared to traditional alternatives. Of course, such a marvelous addition to your home won't run you cheap -- the QuietHome family ranges from $1,495 to $2,495 per door
, so you better have dead silence really high on your list of priorities before pulling the trigger (on a silenced Walther PPK, of course).
