Audiohz Posted March 24, 2020 Report Share Posted March 24, 2020 So the question is with a box say tuned at 32hz is that bringing the over frequency range down to have top end lpf set at 50 to 60hz ? Box I have now has an sa10 right under 1.0 cubic foot tuned at 32 hz displacement probably has it about 34hz imo but when I set my lpf with my smd cc1 at 100hz to 125hz it sounds absolutely terrible. Once I try dropping down to 60 to 80 it gets a little better. Is this normal for 10’s ported? Link to comment Share on other sites More sharing options...
CstrokerV Posted March 24, 2020 Report Share Posted March 24, 2020 why would you even think 100 to 125 hz would be a good lpf point for a sub? i usually don't set higher then 80 and never had really any problem with the sound at that frequency with any size i have used And i usually port 33 to 34 hz ... Are you sure you are setting everything right And what doesnt sound right? my build http://www.stevemeadedesigns.com/board/topic/142505-small-build-log-4-dc-lvl3-10s-tl-update-link-to-rebuild/ http://www.stevemeadedesigns.com/board/topic/154258-rebuild-6-lvl3-12s-update-small-video-nothing-spectacular/ new build http://www.stevemeadedesigns.com/board/topic/188181-03-trailblazer-slow-build-8-dc-lvl3-12-m1-motor-m2-parts/ Link to comment Share on other sites More sharing options...

AaronT Posted March 24, 2020 Report Share Posted March 24, 2020 100 is highest possibly accepted, not ideal. 125, is ridiculously high. Only way I'd do 100 is at a 18db-24db slope. I have my mid 6.5s at 80 up at 18db and sub 80 down at 12db. Shoot for 80 down at 12db slope it'll get a bit higher than 80 through but not much Link to comment Share on other sites More sharing options...

The only way it sounds good to me and my Cousin that I’m tuning for is below 56hz. SSF set to 28hz . Link to comment Share on other sites More sharing options...
