In clamping up my speaker cabinets that I just made, I noticed that on one of them, where the back is glued to one of the sides, there was a shortage of glue. It was too late to take apart, so I used a nail gun to secure them. The sound of speakers are affected by any air moving out of the cabinet, so I’m looking for suggestions to fill in the very tiny gap.

Suggestions please.

I’d suggest epoxy.

You should always caulk the inside seams in a speaker cabinet regardless of how well you glued it up. You want it 100% airtight with the exception of the port.

I wonder if the sound is really that badly affected by a tiny gap maybe we have been taught to expect poor quality of sound bvecause of these defects, but it may well be better leaving alone unless your totaly convinced it’s affecting your enjoyment of the music.Anyway as a man who’s made a good few speakers I would remove the speakers and feed your hand through and maybe caulk it or silicone it or just aplly some thick glue till the gap is sealed it should be a small job good luck.Alistair

I appreciate the suggestions. Caulking won’t work because I’ve glued insulation on the inside, and the cabinet is tall and too narrow for me to reach the “problem” area.
Scotsman, I also wonder if we haven’t gone somewhat overboard regarding certain deficiencies. After all, woodworkers tend to be perfectionists. The speakers sound awesome as is. But because I am one of those perfectionists, I would like to follow Julian’s suggestion of 100% airtight cabinets.
I’m going to spray paint a nice finish on the MDS cabinets, so I have been giving consideration to using P38 to fill/cover the gap and other imperfections prior to using two coats of undercoating. I would think that would offer a 100% airtight cabinet.
