WINISD is graphing that with 1800 watts applied, your port velocity should be below 24 m/s. Definitely use subsonic filter at 25-28hz to not exceed excursion limits at lower frequencies. sooo... attempting to make a model in sketchup and well... i cant seem to get 48" of port length. should i be folding the port over itself?

Hellbilly429 Posted July 23, 2018 Report Share Posted July 23, 2018 Depending on the mounting depth of this sub, you should be able to get away with an L-Port with an addition port wall on top of it like this: 2018 Honda Civic Sport Hatchback (build in progress) NVX Sound Deadener (Front Doors) Stinger FAST Rings Stock Electrical SSA Evil 6.5's Front Speakers Stock rear speakers MB Quart ONX4.80 speaker amp Rockford Fosgate T-1500bdcp DC Level 4 12" D1 @ 2-ohm Box In Design Stage Stock RadioMy Build Log Link to comment Share on other sites More sharing options...

Hellbilly429 Posted July 24, 2018 Report Share Posted July 24, 2018 That port volume is already calculated into the design, so no, won't reduce the volume of the box from the design sent. Good! You should have clearance then. From the port wall to the inside of the sub baffle should have 10.25" of distance left. Depending on if you mount the sub on top of both baffles, or recess it into 1 baffle, you should have 4-4.75" of clearance behind the sub when mounted. 2018 Honda Civic Sport Hatchback (build in progress) NVX Sound Deadener (Front Doors) Stinger FAST Rings Stock Electrical SSA Evil 6.5's Front Speakers Stock rear speakers MB Quart ONX4.80 speaker amp Rockford Fosgate T-1500bdcp DC Level 4 12" D1 @ 2-ohm Box In Design Stage Stock RadioMy Build Log Link to comment Share on other sites More sharing options...
