NOS – New Old Stock

As an in-wall speaker, the DS500 is unlike any. Triad even calls it a “Soundboard” since it literally behaves like one. Its designed to “disappear” into the room its installed in which is why it is incredibly thin – 1.6″. The speakers measure 13.6″ x 17.75″ and will need a similar opening dimension to blend seamlessly into the wall. They can be plastered (maximum 2mm thick) or wall papered over where the speakers will become indistinguishable and people will think music is coming out from your wall! They are not full range and will need to be paired to a subwoofer to get down to the bottom octaves. Triad has an optional amp that they sell ($1,300) which will power up these speakers and send the bass notes to a separate subwoofer. We don’t have that piece but you could get an active subwoofer or passive subwoofer and an amp to achieve that same goal.  Speakers are NOS – New Old Stock and only taken out for the pics you see here. They will be securely packed for safe shipping.
