bought this sub back in january and finally installed it in my truck about a month ago was in a sealed box about .7cubes and heard some air leaks first thought it was coming from a gap when i mounted the sub to the box. turns out a small spot on the dust cap was glued so i had to buy some goop and fix that works great after. recently started building a ported box and was going to mount the sub in the new box and was just doing a look over on all the parts before i mounted it and noticed a bit of glue missing where the cone meets the spider, it isnt seperated just missing glue it looks like. cant say if it was user error or just a mfg defect, sub hasnt been pushed hard in the little time ive used it. can i use more goop and fix that up or what? i hope its easily fixable the sub sounds great and getting a recone/new sub from ssa is kinda a hassle living in canada
