Q: Is there any back-box available for this either at Bestbuy or on MartinLogan website?
A: Hello. Thank you for your question and we hope all is well. We don't have any backboxs for the Helo 12. If a backbox is needed, you can take a look at the Dynabox from Dynamat. Note, that adding a backbox will reduce bass output, so we wouldn't recommend using a box unless they really need the sound control. We hope this helps and please let us know if you have any other questions. Thank you for your support.
