Plotting on WinISD

Alright so i was working on designing a 4th order for 4 10's. i decided on 2.6 sealed and 5.2 ported tuned to 43-45. i plotted 4 DC level 3's and 4 T3 t.600's. Can someone tell me which of these would be more desirable for a daily driver? they both have almost the same bandwidth but the t3's have a peak at 45 Hz that goes up to 12Db

The t3's are blue and the dc are green.

bump! i wanna see if one would be better than the other or if someone could give me different ported/sealed volumes for either one.

dc's for daily, you do not want t3...

green line seems to have a flatter frequency response which imo would make it a better daily box.

But be warned, win isd simply is not accurate...its a good start to a good box but I wouldn't count on it having the exact frequency response once its in your vehicle

That graph is fugly

Jesus

Maybe sweet for a burp box

Being able to input numbers doesnt help for great box design

Get with one of the designers on here and get some help

Btw bbp6. I get exact results in car

You just need to learn 2nd order harmonics and vehicle loading, etc

These programs can get you very very close to in car resp if you know what to look for

yeah i dont really know about 4th orders but i felt like that graph didnt look right. i know you make really good boxes and designs for boxes but you charge for designs right?

Well of course not, considering the fact that the response curves in winISD do not take into account cabin gain or anything else that may affect the curve.

You can add gain

Usually peaking 2nd order at 40 puts it into perspective.

I charge yes.

Ram is prob alot cheaper than me for bp boxes.

Some people on MARS have had luck with PWK
