SnowDrifter Posted November 2, 2011 Report Posted November 2, 2011 4.5 cubic feet and 11.6 sq in of port to 27hz or 14.5 sq in tuned to 29 hz. Could I get away with the smallish port by doing roundovers on it since I'm only running 1400 watts to a single 15 or should I give it more port? I would like to have it tuned low so I could use it for mild HT use, but I don't want chuffing ~~~~~~~~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

I would like to have it tuned low so I could use it for mild HT use, but I don't want chuffing what sub? My 15's in the HT are in 10cubes each with a single 8" sono for a port. No chuffing at all, tuned to 19Hz, but only 400watts per sub.
miniSPLlancer Posted November 2, 2011 Report Posted November 2, 2011 Ideally you want 12-16 sq in of port per ft3 if you use a round port I believe it's 8-12 sq in per ft3 2011 Mitsubishi OutlanderSony 712 Soundqubed HDS208 Alpine MRV-M500 Transmission line enclosure Soundqubed wiring Knu rca XS Power battery CNF terminals
deeje Posted November 2, 2011 Report Posted November 2, 2011 Tune to 29 since it'll give you more port area --2004 Toyota 4runner New Build Log -2002 Acura Tl-S Old Build Log Team DC Audio spl dust is an option you can get on the coils... it's great for extra 1000 watts of power where can i get this spl dust and how much is it. is it hard to apply? lol

mlstrass Posted November 2, 2011 Report Posted November 2, 2011 Just an FYI, 29Hz is not low for HT. A lot of LFE in movies drop down into the teens, so you risk bottoming out the sub. If you have a SSF on the amp be sure to set it appropriately...
deeje Posted November 2, 2011 Report Posted November 2, 2011 Didn't even notice you said ht. Why the space restriction then?

Torres Posted November 2, 2011 Report Posted November 2, 2011 Ideally you want 12-16 sq in of port per ft3 if you use a round port I believe it's 8-12 sq in per ft3 that's not ideally, that's a general rule of thumb. you may need more port, or you may need less port. all just depends. OP...if you're going to do less port, try to keep the port as square as possible to help avoid port noise
