Features

Retrofit Back Box: The C6-HT Retrofit Back Box is designed specifically for Martin Logan's MC6-HT in-ceiling loudspeaker (sold separately). The C6-HT Retrofit Back Box installs directly onto the back of the MC6-HT in-ceiling speaker and secures to the loudspeaker using the included screws. The C6-HT features speaker wire inside the back box which attaches to the spring-post terminals of the MC6-HT speaker. On the outside of the back box are spring-post terminals for connection to your in-wall speaker wire from your receiver or amplifier. The back box helps to protect against dust and dirt, while also ensuring well balanced sound with less bleed-through to the space above the ceiling.

  • The C6-HT Retrofit Back Box mounts to the Martin Logan MC6-HT in-ceiling speaker and not the ceiling. The MC6-HT will still use its "dog-ear" style mounting clamps to secure the speaker to the ceiling. The C6-HT Retrofit Back Box is not a rough-in mounting bracket.
  • The C6-HT Retrofit Back Box measures 10.1875" in diameter and 6.625" in depth.
