I am trying to mate some SB Acoustics drivers and passive radiators together. They are literally made for each other, however, when I enter it into WINISD it is simulating what I assume to be an improper frequency response. Part numbers below:
Driver:
5×8″ SB15SFCR39-4 / Paper
Radiator:
5×8″ SB15SFCR-00 / Paper
These are small 5x8 drivers so I would think they wouldn't require a huge amount of space.
Can I get a sanity check? Yellow is the passive radiator. Blue is it vented. The vented looks great. I would think the passive radiator made for this driver would look similar.

The driver Vas is 47.8liters (1.69 cubic feet), it is not designed to go low in a small box, not that -3dB at ~50Hz is low for a 31.5Hz Fs driver.
Looks like your .5 cubic foot box (14.15 liter) Fb is around 50Hz, the PR would need added weight to tune to that frequency in the small box.
Got it. I just find it odd they'd make a driver this size requiring such a huge box. I don't see the use case for it then
Some guys have room to fit a "huge" 2 cubic foot box under their existing cabinets 😉 .

Welter, the "wife acceptance" build parameter says I cannot have that in the living room.
This is for my new office at work though. I am trying to keep it relatively "small". Need to leave room for a couch.... office with a couch has been a long held dream of mine.

Welter,
I think I have become opposed to subwoofers playing from a different point source outside of the mid and tweeter. I have spoiled myself with 3 ways and now I can't go back

Your woofer/midrange acoustic crossover looks to be around 300Hz, definitely want them co-located that high, easy to hear where 300Hz originates.
If a low distortion subwoofer is crossed steeply below ~125 Hz, it is pretty hard to determine it's location in an acoustically small room.
Anyway, subwoofer means "below woofer", not "below midrange" 😉
