GoldRiver Posted November 16, 2020 Report Share Posted November 16, 2020 My first box. JL spec slot port. I put a couple beefy wooden dowels in the port for bracing and one corner brace and never accounted for the volume loss. This probably reduced port vol enough to increase the velocity. Its being driven by a DC 2.0k dialed back. Here is a photo of the dowels. I am designing a new enclosure. I will post it soon and hopefully you all can give feedback. It will be around 4 cubic feet, tuned to 20hz, slot port. Link to comment Share on other sites More sharing options...
CFD Posted November 16, 2020 Report Share Posted November 16, 2020 Take your subwoofer out and put a gasket of some sort between it and the box and try again unless you already used a gasket. It does sound like air, but not sure if it's from the port. If the subwoofer isn't sealed to the box it can make noise like that. I've seen people use rubber and blue tac as gasket before.
