Start with WinISD and the move on to BB6 or Hornresp, like Triticum recommended. Thats the best way to feel it out, other than spending a ton of time testing.

I was just thinking of space constraints. Hell I have an idea for a box coating I wanna try. I have never seen it done and it's badass. Researching it now. So I totally understand.

WalledSonic Posted March 7, 2018 Report Share Posted March 7, 2018 I designed my current box with termpro and it was off 7hz on tuning (33 turned into 26). I would not recommend termpro. Winisd alpha is free and we nailed my buddy’s 4th order with it. Havent done a parallel 6th in it though. You have two options here. Do like triticum said and learn the softwares or do like kalilac said and do a shit ton of testing. 6ths are fickle beasts (read the series 6th port area thread) and require a lot of iterations (whether in simulation or real world test) to get right.

For a parallel-tuned box the low chamber is going to be pretty similar in terms of size and tuning to what you would use for a ported box for those subs. You might tune a bit lower, like 28-30 Hz. For the high chamber I usually shoot for the tuning to be about an octave higher than the low chamber, and then I size it to get the frequency response I'm after. The high chamber will be much smaller than the low chamber. On 3/7/2018 at 9:38 AM, WalledSonic said: I'd be surprised if you have enough volume in the Mazda (323?) for (2) 18s in a 6th. Check out Gary's build log, he has (2) 18s in a parallel 6th and he has a whole truck bed for it. is there any problem with using the same diameter port for each chamber? i feel like i've heard that somewhere? also i have given up on my 18 dream and im going to try doing 2 12s instead that way im not limited on what i can do with the box Link to comment Share on other sites More sharing options...

If so my calc should work fine.
