Banshee421 Posted March 13, 2012 Report Share Posted March 13, 2012 Can you go lower or higher than the slot port rule of 12-16 inch per cubic foot. What one gives you better sq and which one gives you spl. Quote Link to comment Share on other sites More sharing options...
SnowDrifter Posted March 13, 2012 Report Share Posted March 13, 2012 12-16in is just a rule of thumb. I've done boxes with 11sqin per foot and 18 sqin per foot. Both sounded good, both had a flat response, both dug into the low 20s. Just depends on your application.

TheNewbie Posted March 13, 2012 Report Share Posted March 13, 2012 Don't quote me on this being that I'm still learning about boxes. But SEALED is going to lean more towards SQ ported for SPL. So that tuning your getting on the torres is for SPL it's a general rule of thumb of what it should be inbetween for subwoofers when dealing with a slotted port.

No. Ported, if you do it right, yields a flatter response than a sealed box. The only time I really ever recommend going with sealed over ported is if you don't have enough space to do a proper ported box. Sealed>ported for SQ is just an old wives tale lol Quote ~~~~~~~~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...

Flatter response as in? I just noticed the sealed have more of a punchy response rather than a port has the longer dragged out boooom. Well i've always had ported so im good so far:D EDIT: Wise tale is also that sealed is better for rock ect and ported is for rap as well correct? I've always been basing it off those.

carshateme Posted March 13, 2012 Report Share Posted March 13, 2012 I was about to say...although JL have a knack to sound better in small sealed box. Ported sounds way better than sealed. I try to keep it in between 14-16 ported area, tuned at 32-36hz. I listen to all sort of music. Quote New build coming soon.

Banshee421 Posted March 13, 2012 Author Report Share Posted March 13, 2012 Was thinking about would a smaller port area give u more cone control maybe ? Maybe there is a little bit of back pressure built up. Quote Link to comment Share on other sites More sharing options...

Smaller box more cone control, bigger less cone control if im not mistaken .. which I could very well be if I am well.. heres a free bump Quote Check out my build log: http://www.stevemead...60#entry1958353 Different folks have different strokes.

mrd6 Posted March 13, 2012 Report Share Posted March 13, 2012 smaller port area can give you more cone control but there are alot of other factors that go into determining that as well Quote My Build Log: http://www.stevemead...-sundown-power/ Team NorthWestSPL Link to comment Share on other sites More sharing options...
