I have a DIY cylinder sub built by someone else. Had a 3" flared port in it which had very little port noise. I decided to replace it with a 4" flared port to completely get rid of port noise. After i replaced it i get much more port noise at high volumes now. I was wondering if glue runover inside the port might be causing this? the 3" was smooth inside and on th 4" i might have went a little crazy with the glue. Would that cause port noise? Thanks for any info.
