Cwallaker Posted January 28, 2016 Report Posted January 28, 2016 Simply based on the T/S parameters,would someome be able to model how this driver might behave in a 1.47 cu sealed enclosure. 2ohm or 4ohm running aprox 500 watts Edit* (posted T/s info below)
Hugh G. Rection Posted January 28, 2016 Report Posted January 28, 2016 Modeling that wouldnt be too difficult, but accurately modeling this with cabin gain of a particular vehicle factored in is the kicker. Owner of BigAss Ports

Triticum Agricolam Posted January 28, 2016 Report Posted January 28, 2016 Is that the Infinity Kappa 12? "Nothing prevents people from knowing the truth more than the belief they already know it.""Making bass is easy, making music is the hard part."Builds:

Triticum Agricolam Posted January 28, 2016 Report Posted January 28, 2016 Here ya go: Blue line is raw output, green line is with a rough approximation of cabin gain added in. Like Hugh said, the trick is estimating cabin gain. My approximation above can give you a rough idea, but your actual results could vary significantly. With that being said, that sub looks like it will do well in a sealed box of that size. Your cone excursion should be reasonable with 500 watts.

Joe X Posted January 28, 2016 Report Posted January 28, 2016 Here's a take from some other software, in car cabin gain is estimated: Red = outdoors 1 cubic feet net Green = in car 1 cubic feet net Yellow =in car 1.5 cubic feet net (what you asked). Cone displacement at 500W: As you can see upsizing the sealed box result in a rather mild gain, arguably the larger box size and increased driver excursion will help the driver cool itself a little better.
Cwallaker Posted January 28, 2016 Author Report Posted January 28, 2016 Thanks guys . I was hoping my ears were right . I had it in the 1cu ft the manufacture called for. When I added .47 by removing some wood blocks , It really did sound better . Lower and louder .I need to get a computer so I can Play with these softwares . These subs are not going to win any spl contests but, they are smooth. If I wanted to try ported for more output , could I add an external port of some size to this box ? Any opinions for a tuning freq ? I listen to every thing from bon iver to gorilla Zoe .
Cwallaker Posted January 28, 2016 Author Report Posted January 28, 2016 Heres the sub and box. Straight utility. 5/8 mdf . Lots of bracing . Lined with resin internal . Line x bedliner externally. 1 lb stuffing each
