Bdurb Posted November 29, 2012 Report Share Posted November 29, 2012 So i plan on starting my new build, and this time i want to do a fourth order, im still learning a lot but i have sucessfully walled a car before, well pretty successful. anyways 2 Obsidian 15s 2 audiopipe 1500s was debating the different ratios and tuning. im not concerned about being competition worthy as much as i am pounding the lows. here was my idea, constructive criticism is highly welcome. 5:1 ratio, 4 cu feet sealed, 20 ported. 40hz tuning. is this logical? should the ratio change? i have a jetta wagon with the room to allocate this.

Blackedout Posted November 29, 2012 Report Share Posted November 29, 2012 What kind of car is it first? The design doesn't seem logical, but we need to figure out your platform first Trunk Build Log Link to comment Share on other sites More sharing options...
Bdurb Posted November 29, 2012 Author Report Share Posted November 29, 2012 yeah i mean that utilizing the majority of the space, i hear mixed things about the ratios, some people tend to swear by the bigger is better ordeal My old Build Log! http://www.stevemead...der-in-a-jetta/ Two Obsidian 15s V2 Two Audiopipe Apsm 1500s Fourth Order Wall TEAM CLEARLY LOUDER TEAM OBSIDIAN AUDIO Link to comment Share on other sites More sharing options...

Blackedout Posted November 29, 2012 Report Share Posted November 29, 2012 Cone area is going to be more vital than anything. The power you are working with is fine. The space you are trying to consume with 2 15s isn't normal by any means. 4 15s, even lower quality 15s would occupy that amount of space better. Say 8 sealed 16 ported... Edited for bad math. Being that it hasn't been done yet, I can't tell you not to give it a shot... But if you approach it, you should have the mindset that it probably isn't going to work out the first time, or maybe even the second of third.

Bdurb Posted November 29, 2012 Author Report Share Posted November 29, 2012 ok i really appreciate your honesty. so now for the suggestions. lower the ratio to a 4:1, 3:1 or 2:1? and so i understand, you're saying the response probably wouldnt be that reat?

Neckbeard Posted November 29, 2012 Report Share Posted November 29, 2012 Also, 5:1 is not that great of a ratio. Shoot for 2:1, 3:1, some people even do 1:1. 5:1 is way to fucking big and doesnt really do any thing to help the performance Build log, Super slow!!: http://www.stevemeadedesigns.com/board/topic/168096-slow-neckbeards-1970-opel-gt/ Link to comment Share on other sites More sharing options...
