need help with 4th order

[jacob123]

i gotta zv6 18 and the taramps bass 5k im trynna do a 4th order i did my measurements and i got 14.48 cubes before i add the sealed section. so i was thinking 4 cubes on the sealed side and that would leave around 10 on the ported side just need thoughts before the final decision.

Are you wiring to 2 ohm for 3200WRMS?

[jacob123]

the sub is d2 and the amp is a 1 ohm so i wired it to 1 ohm, how much air space u think the zv6 needs on the seald side

Your cone excursion with a 4,10@45Hz  4th bandpass with the Sundown Zv6 18D2 on 5000W is as follows:

 

 

As you can see at lower frequencies you hit Xmax =35mm, setting your subsonic filter to 20Hz can avoid that happening or consider less than 4 net.

 

Other than that your projected frequency response using a 2.5:1 chamber size ratio will be very peaky like shown in the figure below.
