BoomZoom808 Posted October 18, 2013 Report Share Posted October 18, 2013 Hey guys I want to do my first aero port box for a SDC2.5 15 D4 I just ordered. I am going to use the DD 15" compact Box plan but switch to Aero's to save some space and gain some efficiency hopefully. I am pretty sure this box will fit in my trunk. 24 wide X 19 Deep X 16.5 High I plan on using the Aero ports below which come in 3" diameter by 6" long or 4" by 6" http://www.rtboxes.com/accessories-aero-ports/ My question is should I used two 3" ports tuning to 35hz or a single 4" port tuned to 33hz? Thanks for any input you guys gave throw my way! 2010 Mazda 3s 2.5L Pioneer DEH-X9600BHS Knu OFC 1/0 SS Platinum AGM / XS Power XP750 Alpine PDX F-4 / Morel Maximo 5 + Coax 5 IA 10.1 / SSA XCON 12 Link to comment Share on other sites More sharing options...
B-Sh0t Posted October 19, 2013 Report Share Posted October 19, 2013 A 4in port will be more efficient. How many rms you plan on using on that sub? Link to comment Share on other sites More sharing options...
Krakin Posted October 19, 2013 Report Share Posted October 19, 2013 Why are you trying to use 14 in2 of port? I use that on my 10" and I get noticeable noise. Try that with a 15 around with close to the same xmax it will be much worse. You also need to put in your driver displacement.

I would have replied earlier, but I was measuring the output of my amp with a yardstick . . . What you hear is not the air pressure variation in itself but what has drawn your attention in the two streams of superimposed air pressure variations at your eardrums An acoustic event has dimensions of Time, Tone, Loudness and Space Everyone learns to render the 3-dimensional localization of sound based on the individual shape of their ears, thus no formula can achieve a definite effect for every listener.

BoomZoom808 Posted October 19, 2013 Author Report Share Posted October 19, 2013 Thanks guys going to get a 6in aero instead. 9-12in per cu I hear is recommended for aero ports. Not really too concerned about the driver displacement was more concerned about chuffing 2010 Mazda 3s 2.5L Pioneer DEH-X9600BHS Knu OFC 1/0 SS Platinum AGM / XS Power XP750 Alpine PDX F-4 / Morel Maximo 5 + Coax 5 IA 10.1 / SSA XCON 12 Link to comment Share on other sites More sharing options...

Krakin Posted October 19, 2013 Report Share Posted October 19, 2013 For port noise I would see if you can fit in a 8" port. And if you can read through this. Flaring will help a whole lot. http://www.subwoofer-builder.com/flares-25mm.htm Krakin's Home Dipole Project http://www.stevemeadedesigns.com/board/topic/186153-krakins-dipole-project-new-reciever-in-rockford-science/#entry2772370 Krakin, are you some sort of mad scientist?

I am pretty sure I can get a 6in precision port locally but that is a good link for DIY ppl I don't have a router and don't really want to mess with it. I am hoping I will keep this setup for a while 2010 Mazda 3s 2.5L Pioneer DEH-X9600BHS Knu OFC 1/0 SS Platinum AGM / XS Power XP750 Alpine PDX F-4 / Morel Maximo 5 + Coax 5 IA 10.1 / SSA XCON 12 Link to comment Share on other sites More sharing options...
BoomZoom808 Posted October 30, 2013 Author Report Share Posted October 30, 2013 I wanted to bump this up for port/sub orientation suggestions. This box is going in a 05 Mazda 3 trunk. I was thinking sub up port to the drivers side or sub back port to the drivers side. I don't have enough depth to do port back and sub back since the port is 18" long with the flares on and the box is only 19" deep. 2010 Mazda 3s 2.5L Pioneer DEH-X9600BHS Knu OFC 1/0 SS Platinum AGM / XS Power XP750 Alpine PDX F-4 / Morel Maximo 5 + Coax 5 IA 10.1 / SSA XCON 12 Link to comment Share on other sites More sharing options...
Joe X Posted October 31, 2013 Report Share Posted October 31, 2013 Your box above looks smallish for that sub, either way, at least a 6" port flared on both sides firing driver's side, sub firing frontwards or backwards. Link to comment Share on other sites More sharing options...
BoomZoom808 Posted October 31, 2013 Author Report Share Posted October 31, 2013 Thanks Joe X that's exactly what I did. I know it's definitely on the small side but it's within SQ's minimum requirements and I plan on giving it 1k. Going to mount the sub tomorrow and start breaking it in. 2010 Mazda 3s 2.5L Pioneer DEH-X9600BHS Knu OFC 1/0 SS Platinum AGM / XS Power XP750 Alpine PDX F-4 / Morel Maximo 5 + Coax 5 IA 10.1 / SSA XCON 12 Link to comment Share on other sites More sharing options...
