IKnowImLost224 Posted April 16, 2012 Report Share Posted April 16, 2012 I know most of you probably think a sealed box for this sub is stupid but I wanna try it and see what result I get for a SQ setup. Just trying to figure out what I should do as far as internal volume. RE recommends 2.1 cu ft but someone the other day suggested 3 cu ft. At what point will a sealed box be too big where I could risk damaging the sub? Also when tuning an amp for a sealed box where do you set LPF and subsonic?

Robby Holmes Posted April 16, 2012 Report Share Posted April 16, 2012 i had a L port box @ 3.92CuFt after displacement, and it sounded absolutely fantastic. so i mean i know it doesn't totally pertain to having it in a sealed enclosure, but take it for what its worth. if i remember correctly, isn't there a formula or spread sheet for recommendations to convert from ported to sealed internal volumes?

What did you have it tuned to? And im not sure about there being a chart for converting but RE has specs for both sealed and ported im just wondering when a sealed box becomes too big and when it can damage a sub.

Robby Holmes Posted April 16, 2012 Report Share Posted April 16, 2012 (edited) mine was tuned to 32.9Hz absolutely killed on the lows not totally sure on when it becomes too big, i never much dipped into sealed boxes Edited April 16, 2012 by Robby Holmes Quote '08 Chevy Cobalt coupe 2.2 base model trunk build: 2 9512iSC flatwound alum 1.5 coils -extra 9500 spider pack -8" platinum carbon dustcaps 1 DD Z1 (.375ohm nominally daily) 3g31 AGM 320a Ohio Gen alt 1 DD S4 4 channel 4 VO-M8v1's (holes cut for 3rd pair) 2 CS 6.5's 2 VO-B1's Sony XAV-601BT all Knu Krystal RCA's Cadence 7band EQ ______________________ 148.3db @ 32hz (burp) 148.4 @ 37 & 38hz (burp) 146.xdb 90sec average (center windshield) Link to comment Share on other sites More sharing options...
IKnowImLost224 Posted April 16, 2012 Author Report Share Posted April 16, 2012 I was considering making another one tuned a little lower also. I am currently around 35 hz, which doesn't sound bad. I just re tuned with the DD-1 and it was sounding real good! But I either wanna go sealed or aero ported on my next box. Just not familiar with either Quote Link to comment Share on other sites More sharing options...

Joe X Posted April 17, 2012 Report Share Posted April 17, 2012 Any other help for sealed box's? Block th port of your current box with some MDF to get an idea of what sealed will deliver. Quote Link to comment Share on other sites More sharing options...
