dwright27 Posted March 7, 2011 Report Share Posted March 7, 2011 id do 35 hz to keep a good "range" so to speak and still play low. 5 cubes will be more efficient with the power you will be feeding it. if you was doing 4000 RMS + i would say 3 - 3.5 cubes, but youre not. 2006 F-150 4 DC XL M2 18's Walled Daily Driver XS Power 4 DC 3.5kw Team DC Team S.P.L.

David12460 Posted March 7, 2011 Author Report Share Posted March 7, 2011 Okay, Can I get a bit of help with the same dimensions listed above? I need the sub and port facing upwards. If I point the port towards the back I think It will be too close to the rear door and the targeted frequency will be off. Link to comment Share on other sites More sharing options...
RAM_Designs Posted March 7, 2011 Report Share Posted March 7, 2011 Yeah, you'll definitely need a bigger box with that power. 4-5ft^3 will work fine, tune in the 33-35hz area.

David12460 Posted March 7, 2011 Author Report Share Posted March 7, 2011 I'm running rough numbers in the box calculator that most people use on here. I have read a that 12-16 square inches of port area is ideal. Does this hold true to me? dwright27 recommended 100 sq inches of port area. Can someone help me understand the importance of port area? Why might more or less port area be better than the other with the same tuned frequency. Link to comment Share on other sites More sharing options...
iKidwell Posted March 7, 2011 Report Share Posted March 7, 2011 You want lots of port area because that sub is gonna move a fuckton of air. Go over 16 and do 17-20 in per cube. c'mon now, if i was shooting an 8 year old, it wouldnt be MY 8 year old. i recently got a Pyle PL1590BL and i was building an enclosure for it tuned to 25 hz. i didn't have any tools to cut a circle so i hit it with a big hammer. 2003 Infiniti G35 Sport Sedan Build in Progress Link to comment Share on other sites More sharing options...

SasquatchREG32 Posted March 8, 2011 Report Share Posted March 8, 2011 nothing is wrong, the XL is ust more efficient with anything under 3K. id do 5 cubes or a hair bigger, with 100 square inches of port tuned around 35. Link to comment Share on other sites More sharing options...

David12460 Posted March 8, 2011 Author Report Share Posted March 8, 2011 So the port will face up based on that correct? I need to do that otherwise it will only be 2" away from the rear hatch. Thanks! Link to comment Share on other sites More sharing options...
