this is the situation:
the project is a SW for a 2.1 system (2 DIY amazing DML speakers!) medium size living room
the amp of the sub is a20W mini amp (MUSE EX2)
I am building a box of maximum 21 L (concrete cast)
I have a: Dayton Audio SD215A-88 8" DVC Subwoofer
+ Dayton Audio DSA215-PR 8"
at the beginning I planed to put them on a sealed box and all is good. now after watching some WINISD videos I'm not sure at all what to do.
I have 2 main questions for you:
1. do I have to have a high pass filter because of the cone extrusion? if so can you show me a reference product? (Butterworth 40HZ N2 ? gave the best result)
2. the data I'm getting from WINISD is better when I use a ported style setup, not using a PR at all...is that make sense?

Depends on whether or not there's enough signal < ~ 1/2 octave [0.707x] below tuning [Fb] to excite the PR at rated power [20 W]. Doubtful.
I only have Hornresp
installed, but the only very minor [simmed] differences at 20 W between them are inaudible IME as long as the PR cab is mass loaded enough to counteract any PR 'rocking' vibration, though hopefully the concrete cab's weight is sufficient.
Regardless, the proper way to compare the two is the way us old folks did pre software, which was to calculate the PR's equivalent air mass by calculating [or finding it empirically] the vent length required to tune a vent area [Av] = driver effective piston area [Sd], so how do they compare when the BR is simmed this way?

I hope some day I will be able to understand half of what you wrote. right now, as I mentioned I'm a Newbie...basically heard about partsexpress.com watched a ton of hours of YouTube DIY speaker blogs and tried my luck in designing a beautiful sounding and looking 2.1 system.
can you help me figuring out what are the electronics I need for a SW using this driver on a 21L box and 20-50W of power? if needed
and what are your thoughts on PR vs vented in this setup?
