One of the benefits of in-ceiling speakers is how easily they disappear into a room. Unfortunately, the sound coming from the back of the speaker doesn’t disappear and can distract those in the rooms above the speakers. MartinLogan offers back boxes, or enclosures, for Motion CI In-ceiling speakers. For these situations where sound control is desired, these retrofittable back boxes are the perfect solution. They offer 20dB of noise reduction into adjacent areas and offer the perfect solution to achieve consistent performance where ceiling cavity sizes may vary throughout an installation. Please note that the volume of air in the retrofit enclosure is smaller than that of your ceiling, and bass extension will be reduced. If sound control is not necessary for your unique installation, we recommend not using the back box so the speaker can take advantage of the larger airspace in your ceiling cavity.
Q: Is the back box compatible with all MartinLogan speakers?
A: No, the C6BXR back box is specifically designed to be compatible with the MartinLogan MC6 speaker.
Q: How much noise reduction does the back box offer?
A: The back box provides 20dB of noise reduction into adjacent areas.
Q: What is the product width of the back box?
A: The product width of the back box is 7.62 inches.
Q: Does using the back box affect the speaker's bass performance?
A: Yes, using the back box can reduce bass extension because the volume of air in the enclosure is smaller than that of a typical ceiling cavity.
Q: What is the purpose of the MartinLogan back box?
A: The back box is designed to reduce noise from the back of the speaker, which can be distracting in rooms above the speakers.
Q: does the ICST6 speakers have a similar back box?
A: undefined
Q: Will these fit the Helos12 in-ceiling speakers?
A: Hello. Thank you for your question and interest in our products. This(C6BXR) will not work with the Helos 12, and we don't have a backbox for it. The Helos doesn't require a backbox, but if you are looking for something compatible, there are alternative options out there. Dynamat would be an example of an option to consider. We hope this helps, and please let us know if you have any other questions. Thanks again, and we appreciate your support.
Q: Can you add sound damping material in the backbox before connecting the box to the speaker?
A: Thank you for your question, and we hope all is well. There should be no issues in doing so. It would however need to be done by the individual because they only come as shown in the picture. We hope this information helps, and please let us know if there is anything else we can assist you with.
