Ray Posted June 25, 2011 Report Share Posted June 25, 2011 Bandwidth sure, but just choke the dogshit out of the output. But i suppose your not going for any kind of REAL output.

SkylarDunn Posted June 25, 2011 Report Share Posted June 25, 2011 (edited) Arn't you guys tuning too low for a 4th order? there is no such thing as too low, the tuning is decided by the thiele small parameters, all subs are different. thats like saying that tuning an 8" below 40 hz is too low. it all depends on the drivers. that being said, i dont know why anyone runs Fi, their T/S specs are so terrible, DC subs are better in EVERY way (t/s wide), and im not a bandwagoneer, i havent even touched a DC sub.

Maticus Posted June 25, 2011 Author Report Share Posted June 25, 2011 Yeah, yes I do. I have width but what about depth? I'd like to be able to see into the box from the cab without a 18 inch long port. I'm just not too experienced with tuning and help would be awesome.

Ray Posted June 25, 2011 Report Share Posted June 25, 2011 Dont let your life be decided by bbp6 A 3db bump at 30 is sweet. So 3ported with how much vent? Alot about a 4th order is making sure you can output enough of the sound through the vent. Ive built boxes at 1:1 and smaller I know the difference with in car resp Trust me when i say you will never change my pov. I let real world data tell me what works better, and i have tons of it. Do 1:1 boxes sound good?? Yes. But their usually are 6db down from where it could be. And i dont need 50hz bandwidth 30 is plenty for me Btw, i use bbp6 also Id love to see the vv on your box vs. My box And cd also Quote 2008 California state record holder 157.2 Bassrace2009 California state record holder 157.0 BassraceRollin 50's 158.7db2009 King of Cali Bassrace2009 USACi score 160.5 @ 42hz Link to comment Share on other sites More sharing options...

Ray Posted June 25, 2011 Report Share Posted June 25, 2011 I plotted both boxes. My vent is a little long, yours is tiny Our f3 points down low are pretty much the same Yours plays up to 62 mine cuts at 47 Mines louder at 30 Yours is louder at 52 Louder being 1.5db difference On the graph they look the same at 40 But i know for a fact that in car resp will boost my box from 45 down, which would make it seem like its not flat but in fact it only plays from 50 down. So a boost within its band is a good thing Quote 2008 California state record holder 157.2 Bassrace2009 California state record holder 157.0 BassraceRollin 50's 158.7db2009 King of Cali Bassrace2009 USACi score 160.5 @ 42hz Link to comment Share on other sites More sharing options...
