[QUOTE="I'mPoor:(, post: 8713783, member: 661750"] So, i'm getting back into the audio game. Planning on doing a ported box sealed from the trunk. I have roughly 4-6cu feet to work with, I'm working in WinISD right now but it has been a long time since I have designed (back in 2015). What is the recommended air velocity at your peak DB? Also where would you recommend to have DB roll off? I'm not so interested in below (30hz) due to the fact i'm a little limited in air space and sticking with two 12s. I have a firm DB roll off at 29Hz right now, peaking at 35Hz, rolling back down at 53Hz. If I tune to 30hz, roll off below 0db starts around 27.7Hz and then starts rolling back down at 40hz after peaking at 31Hz. Would love to hear some ideas, maybe I need some sense knocked into me :) and my logic is flawed. Setup: 2018 Honda Civic 4 Door, Two HDX3 12's, Taramps Smart 3, H/O Alt, G31, Dayton DSP. [/QUOTE]
