araarin Posted July 6, 2012 Report Share Posted July 6, 2012 Got a wall with 4 Lvl 3 15's it's around 13.6 cubes after displacement I was told I need around 210 to 240 square inches of port my question is how long should the port be the inner measurements of the wall is 43.25x32x17 and I'm chasing at least a 150 do you guys think its possible Quote Link to comment Share on other sites More sharing options...
mrd6 Posted July 6, 2012 Report Share Posted July 6, 2012 Definitely possible...but this is kinda a big build to jump into without even knowing how to tune your enclosure. Is any of it built already or is this hypothetical? Quote My Build Log: http://www.stevemead...-sundown-power/ Team NorthWestSPL Link to comment Share on other sites More sharing options...
araarin Posted July 6, 2012 Author Report Share Posted July 6, 2012 Yea I actually built it I had it wrapped and everything but I only had a 140 square inches of port I tested it it was loud but nearly as loud if I had don the ports right the first time but this is my first wall build Quote Link to comment Share on other sites More sharing options...

Joe X Posted July 6, 2012 Report Share Posted July 6, 2012 (edited) About 23 deep based on a 35.5Hz tuning 183 square inches of port. Edited July 6, 2012 by Joe X Quote Link to comment Share on other sites More sharing options...
araarin Posted July 6, 2012 Author Report Share Posted July 6, 2012 Thanks but is it possible to bend the port to get the 23 inches Quote Link to comment Share on other sites More sharing options...
Joe X Posted July 6, 2012 Report Share Posted July 6, 2012 Thanks but is it possible to bend the port to get the 23 inches The box I mean, the port would only need to be 15 1/2, and that without a double baffle. Quote Link to comment Share on other sites More sharing options...
mrd6 Posted July 6, 2012 Report Share Posted July 6, 2012 so youve got a pretty small box for these subs. 13.6 cubes not including port, sub, and bracing displacement is going to knock you down to around 3 cubes per 15...how much power are you going to be running? Kinda need to know that before making any recommendations. To save box volume you could always try to do an external port as well depending if it wold fit. Any pictures?
