Soundqubed hdc3.115 5 cu ft box tuned 33hz

[jontaccona]

My sub is not hitting the 20hz range notes 30 and up to about 60 it's really really loud I have my sub sonic filter at 15hz and my lpf all the way down to 50hz is there a way to make the transition bass cleaner too as in like a Gucci mane song produce by zaytoven how the bass goes up down then even lower my sub hit extremely hard on "purple coming in" by future anyways I have a pioneer deh80prs I had to turn off the switch on the bottom for networking mode because my some of my door speakers were working with that on I used the dd1 to tune the gain and the bass booster is off on the amp ... Like when I put young Jeezy put on on it doesn't hit those notes the amp is a shark 3500 I also have a hifonics Brutus 2400.10 amp I can switch with ... I have a 240 amp alt in and 1/0 wire for the shark ... I also have a amp for my door speakers but that's not my problem except I blew a infinity kappa some how idk how anyways I'm getting a replacement any help is appreciated I can send you a good sketch up file of my box it's tuned to 33hz forsure I messed up on the first one and did the second one right

Box is tuned to 33hz and 20hz isn't loud enough? The output from the port will drop off rapidly below port tuning and will cause the sub to unload. This is how people kill their sub and then bash the company it came from because of it.

You should be providing details on the box and vehicle + pics but I can tell you, subs like the SP4 likely would fit your application better.

I'll take pictures and give demensions but off the top of my head this is what I believe they are port width is 5.8 inches port height it's 16.5 inches box depth is 20.5 inches box length is 47 inches box box height is 18 inches and port length is 31 inches give or take I have L slot so it's like 14.75"x13.25 I know that does not equal 31 but I removed half of the port width 5.81 from the second port to make the port have the same demensions all the way through idk if that makes sense

Can't post any pictures here

Have to use photo bucket.

Johntaccoma i replied on ur 98 dakota post, ur gonna get the same answer here either way. And just like shade tree said, if ur tuned to 33hz you set ur SSF 1/2 octave below tuning so about 25-26 hz... Setting ur SSF to 15hz is s big no no lol you will run the chace of damaging ur sub pretty quick. Also just because you build a box to play down to 20hz doesnt mean the sub will... I mean it will but you may not get the output your wanting due to sub capabilities.

[jontaccona]

So take it a couple clicks above 15? And thank you

Having your LPF set to 50 hz is probably contributing to your subs transitioning poorly. It will also make your mids work harder than they need to, you may consider turning that up a bit.
