Ben C Posted November 9, 2017 Report Share Posted November 9, 2017 Hey friends, I have a small diaphragm condenser, bought used, that the previous owner kept in a homemade PVC pipe contraption. The pipe is sealed on one end, with the end cap being removable and held in place by how snugly it fits. I wonder if keeping a mic in there could cause problems, because if you pull the cap off it creates a "pop" sound when I create a low-pressure situation in the pipe. Some thoughts; if there's no closed air space inside the mic/capsule/diaphragm, then this air pressure will affect the whole thing evenly and not create any problems. But if there's an enclosed air space, the differential pressure could be enough to put strain on the mic. Any thoughts welcome! Quote Link to comment Share on other sites More sharing options...
Eric Toline Posted November 9, 2017 Report Share Posted November 9, 2017 Plug in the mic and test it. If it sounds good, it is good. Don't sweat the petty stuff, Quote Link to comment Share on other sites More sharing options...
Jim Feeley Posted November 9, 2017 Report Share Posted November 9, 2017 Interesting. Maybe you could drill a small hole in the cap or pipe? Too calm your concern if nothing else. Quote Link to comment Share on other sites More sharing options...
Glen Deakin Posted November 9, 2017 Report Share Posted November 9, 2017 Like Eric said don't sweat it. Would rather protection then no protection. But... If your so worried try this. Quote Link to comment Share on other sites More sharing options...

Jakobk Posted December 30, 2018 Report Share Posted December 30, 2018 In a pipe or not, surrounding air pressure changes constantly. Any mic will handle this. Don't worry... Quote Link to comment Share on other sites More sharing options...
tourtelot Posted January 1, 2019 Report Share Posted January 1, 2019 I used, and still have a few, PVC tubes for a long time. Never had a problem. Tried cigar tubes but needed to drill a little exhaust hole in the cap or I couldn't get them to close. Back now, mostly, to wooden boxes, but I no longer live on a camera truck. D.
