Hello everyone!
I'm new on the forum and i'm hoping to find some help sorting things out.

I am going to build a ported subwoofer to use in a studio environment for mixing and mastering.
So my goal is to reach as low frequencies as possible and get a linear sound.
I don't want to sacrifice too much punch to reach these low frequencies tho.
I'm aiming to get somewhere below 25hz atleast. lower if possible without sacrificing accuracy.
The sub and amp i am going to use are the following:

SCAN-SPEAK DISCOVERY 30W/4558T00
ZACHRY DSW-500N

I have been trying to enter the required parameters on the sub into WinISD,
But when i click save, a consitensy check is done and say that all the parameter groups failed.
So i can't get further than that, and thats where i´m at right now.

According to factory specs for the sub it has an FS of 17hz but on some forum some guy made
measurements after the breakin period and he only got down to 20,80hz something.
some other specs were of too.

I don't have the advanced super expensive tools to build a too complicated enclosure.
So here i am asking for some suggestions. Something that can produce linear and super deep bass
with while being accurate enough for mixing and mastering in a treated studio environment.
The studio is a bit too small but might move to a bigger locale later on.
I will use a pair of KRK VXT8 until i can afford an upgrade to Event Opal.
Ive had these krk monitors for a year now perhaps and i have worked with genelec, dynaudio,
mackie, alesis, adam and so on.
The reason i want a custom buildt subwoofer is that these brands subs that are designed to go with
these monitors do not reach low enough frequencies and/or are too loud or punchy just to sound more
attractive to the customer. Sure they are useful but they don't suit my needs.

Perhaps someone already buildt a good enclosure for this sub and already have a finished enclosure design.
Or the volume of the enclosure with diameter and length of the port that suit my goal.
Perhaps some help getting WinISD sorted out so it works. Any help is appreciated, So i'm all ears! :spin:

Thanks! Those were some helpful links. about the quested monitors. together whith a sub i can guess they will sound alot clearer than event opal. but they might be too big for that little studio i'm building the sub for. Anyways. The link you provided to Madisound had this little recommendation. "For a vented box of 2.5 cubic feet, 3" vent by 11" long, your F3 is 27Hz." wouldnt that port be a little too slim?

Port length grows up in proportion to the area (maintaining the same alignment).
Some considerations, if in your project you can have a straight port, without that 90º curve, that would be a bonus. I would have that in consideration for a studio. (Port Effective Length pic) 🙂

I used a plastic pipe with flares in my previous subwoofer build. the only thing i couldn't get through the software i used was the port length. that project was for a car sub tho. imjust thinking that i can reduce the size of the box with a slot port. and ofcourse ill make things as rounded as possible without a router wich i don't have or even a place to use it. But is it not better with a smaller chamber inside for more compression using that zigzag kind of slot port? Any other benefit of a straight port sonically exept for less turbulence?
