The super flat Taperwire 16 AWG speaker wire can run under carpets to invisibly wire stone and brick buildings such as churches.
Out of sight:
To enjoy audio you don't need to see the speakers, you don't need to see the cables, and it's easier to focus on what is being said or heard when these distractions are removed. Taperwire's flat cables make this possible. Without drilling holes in walls or installing complicated tubes, you can run speaker and audio cables just about anywhere.
The cables are so thin that they don't add any noticable mass under carpet. The white outer coat can be painted to match its surroundings while the self-adhesive bottom makes installation easy.
Four full conducting wires are built into this single flat cable to run two speakers at once for stereo sound.
