Joe X Posted March 18, 2013 Report Share Posted March 18, 2013 Looks within specs, the port looks ok, the extensions should be around 3.5" long, the port and side panels would need bracing as well. threaded metallic bracing can be used for excellent results.

john253a Posted March 18, 2013 Report Share Posted March 18, 2013 if you can get closer to 16net @ 32 it will give you a flatter response, youll just have to be a bit more careful at full tilt idd drop the port size down if you cant go larger in the box to high 14 15flat Link to comment Share on other sites More sharing options...

john253a Posted March 19, 2013 Report Share Posted March 19, 2013 Im looking for straight output. Obsidian only recommends a max of 3.75per. then why you tuning so low, get it up between 37-42hz youll be supprized how musical you still are upto or at 42hz side note Obsidian only "recommends" a max of 3.75per but if your chassing output no need to go any higher Link to comment Share on other sites More sharing options...
john253a Posted March 19, 2013 Report Share Posted March 19, 2013 also check your torres sheet as theres something very wrong with the port volume it should be in the mid 3's not mid 5's Link to comment Share on other sites More sharing options...
