JD1000/1 and impedance rise question!!

[1point21gigawatts]

I already got the box volume requirements from Si. That box I provided takes into account the driver, port and brace displacements too. It's pretty spot on.

Cool.

It happens. Programs are never spot on. Figuring yourself is the best way. the12volt.com is the best for calculators for figuring. On the port figuring if round, you half to add an inch if the aeros are flared. That’s it.

Not sure what you're talking about, that is a slot ported box, not a box with a round port. Slot ports are better, less noise and all. As for the size and length, there is no formula for simply converting a slot to a round port, the volume of the port is what determines the frequency of the tune. And hate to break it to ya, winISD and BASSBOX 6 pro, got more going on than the12V.com.

I know. Just letting you and whoever else know about the calculators just in case somebody wants to build an aero with a big *** port. Winisd is trash. Everybody knows that. Bassbox 6 is more expensive trash. Speaker box lite is the closest program to being correct. Then sub box pro is off by a half inch and then ultimate car audio is off by a half cube. Then winisd is off by a cube and a half inch and then bassbox is off by a half inch and a cube. The charts are not accurate on either and only 2 humans know how to calculate meters per second on air flow. I love you fam.

The one I corrected for you is 1.75 cubes. The one I drew out for him is 1.5 cubes. No program can do this.

You're not figuring net, you're figuring gross. the gross is actually 2.3 cu ft, less port disp of .65 cu ft leaving the rest to be offset by the driver and the braces, comes to a rough net of 1.45 to 1.5 cu ft. But hey, you go man.

Now he isn’t. A goat is an animal.

I Am Love. That’s what I offered to y’all before getting shewed away like a stray goat.

Very few people on this site even know the difference between impedance and resistance

Come now; quit being a tease and just tell us. I'll tell you my take on it. Resistance is a set value, impedance is a reactive resistance.

Sorry @1aespinoza

And this relative to this thread how?

Entertaining at best, but you really shouldn't drop purple microdot or blotter before figuring out enclosure specs, really, not a good idea. But you run with those ideas, let me know how they work out. Ciao!

LOL! I know bud, no worries.

I can tell you what happened in year 901 and year 1351 and tell y’all I just looked out for y’all with my hands.

I heard resistance is what she puts up and impedance is what her father puts up.
