Haro Christian Posted August 15, 2016 Report Share Posted August 15, 2016 Help! lol I built a ported woofer box thinking this would sound A LOT better than my previous sealed box for 4-15" L7's but it doesn't! Hits high bass cool but not lows. Do I need to tune lower by making port longer? The box is 23"H x 49" W x 58"D port is 21.5"H x 15"W x 10.5"D tuned to about 34Hz per Torres Tuning Calculator... What did I do wrong? It is my 1st build so take it easy on me guys I barely get any air out of port. Don't want to give up and cancel the port and just wall the interior and make it sealed.

mothra Posted August 15, 2016 Report Share Posted August 15, 2016 shrink that port by about 20% if nothing changes, nothing changes You don't know what you don't know, till you don't know Link to comment Share on other sites More sharing options...
Jessica Posted August 15, 2016 Report Share Posted August 15, 2016 im showing 31cuft for that box. that seems kind big to me for 6 15's. You are at like 5cubes per sub.

Kicker suggests a min of 3cuft and max of 6cuft per sub. I tried to get the max i could using the space i am not using in vehicle. Link to comment Share on other sites More sharing options...

Joe X Posted August 15, 2016 Report Share Posted August 15, 2016 58D? Do you still have like 17-21" or so port clearance? Link to comment Share on other sites More sharing options...
Haro Christian Posted August 15, 2016 Author Report Share Posted August 15, 2016 58D? Do you still have like 17-21" or so port clearance? Yup, 58inches, i have plenty of clearance. I assume I need to tune lower? Link to comment Share on other sites More sharing options...
Joe X Posted August 15, 2016 Report Share Posted August 15, 2016 You missed to place a 2 in the "# of common walls" field, check your tuning after modifying that field. Link to comment Share on other sites More sharing options...
SnowDrifter Posted August 15, 2016 Report Share Posted August 15, 2016 im showing 31cuft for that box. that seems kind big to me for 6 15's. You are at like 5cubes per sub. They have a TON of cone area for 15s being that they're square @OP how much air a port moves is greatly dependent on the power applied and frequency played. What do you believe the problem to be? Do you have any odd loading issues? ~~~~~~~~SAY NO TO PHOTOBUCKET~~~~~~~~ Snow's DD-1 tracks here: https://www.stevemeadedesigns.com/board/topic/167433-snows-dd-1-tracks/ My take on OFC vs CCA: https://www.stevemeadedesigns.com/board/topic/110381-things-that-piss-you-off-in-the-car-audio-world/?do=findComment&comment=2461444 Link to comment Share on other sites More sharing options...
Triticum Agricolam Posted August 15, 2016 Report Share Posted August 15, 2016 I'd suggest verifying your tuning frequency in vehicle. You can find your real tuning frequency by playing sine wave tones at moderate volume (there are tone generator apps for your phone). At your tuning frequency your cones will move the least and movement will increase if you increase or decrease the frequency from that point.
