Goblenator Posted January 4, 2014 Report Posted January 4, 2014 What is the best subwoofer box tuning software? I have experiance with WinISD but i don't trust it when designing 4th and 6th orders. Are there better programs for using ts parameters to dial in box tuning?
Andreetje77 Posted January 4, 2014 Report Posted January 4, 2014 I think the best one yet is from term-pro,only down side for me is the price.

Goblenator Posted January 4, 2014 Author Report Posted January 4, 2014 not box design but tuning software. i already have torres. i need something that will give me accurate tuning for 4th and 6th orders.

jarrius Posted January 4, 2014 Report Posted January 4, 2014 Wouldent you just tune them the same as a regular box? For 4th order you i would asume you just use the cubic feet of the ported section and plug that info in to torres and calculate tuning likr that. Kinda the same for a 6th just do one at a time. 2012 Chevy sonic1xSQ HDC3 12 D2RF R1200d 140 square foot of Q-Mat(soon to be installed) 140.2Db sealed on the dash with TL 142 DB sealed on the dash with another meter (was dead on with the TL at a show i was at) 141 on music. strangeduck,on 02 Jan 2014 - 01:39 AM, said: when my car spins out i just put the car in neutral, turn in the direction i want to go and pucker my asshole
Goblenator Posted January 4, 2014 Author Report Posted January 4, 2014 i'm not talking about cubic feet and port tuning i'm talking about frequency response based off of the TS parameters of the subwoofer according to the enclosure it's in. Torres can't do that.

For 4th order you i would asume you just use the cubic feet of the ported section and plug that info in to torres and calculate tuning likr that. Kinda the same for a 6th just do one at a time. Yeah they are tuned using the same method as a regular ported box. If you are looking at a more accurate way to do you tuning the best way I have found is using a spreadsheet and the formula and just do it yourself. You can get the formula here: http://www.diysubwoofers.org/misc/portcal.htm The advantage of doing it yourself is you have more control over the end correction. With WinISD you can pick between three different end correction values, but none of those apply to slot ports. Torres doesn't even give you an option for end correction. It may not sound like a big deal, but if your end correction is wrong your tuning can be off by several Hz. I know if you build a slot port using the standard .732 end correction in WinISD your actually tuning will be 2-4 Hz lower than what you intended. Here is the end correction values I use. Two flanged ends 0.850 One flanged end 0.732 Two free ends 0.614 Slot w/ 1 common wall 1.230 Slot w/ 2 common walls 1.728 Slot w/ 3 common walls 2.227 Almost all slot ported boxes are ones with 3 common walls so 2.227 is the end correction you want. I've used impedance sweeps to verify the tuning on boxes I've built and that's what gets me the closest to what I want. If you want to learn more about tuning and end correction you can read about it here: http://www.troelsgravesen.dk/vent_tuning.htm "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:
