Stephens Trusonic 120FR enclosure

[2015]

Sealed vs Ported.
I opened up a 3 way speaker cabinet and found a 120FR being used as a woofer.
The 'FR' means full range speaker (30-15,000hz).
I want to use the 120FR and went online to do some research.
I measure/ calculate the EBP to be between 12 and 35.
The enclosure calculator gives me an enclosure volume 24 cu ft.
Does anyone really use an enclosure this big for a 12" fullrange speaker?
VAS= 7.5 cu feet
Fs= 37HZ
Qts= 0.56

I used an online speadsheet and measured the Qtc to be 1.6.
The enclosure calculator gave me 700 cu ft ported!!!
What would be a good home for this 12" speaker?

The Qts is .56, so the required enclosure volume should be about 4.2 cu. ft.

Thanks sealy
4.2 I can do.
How did you get that number?
Would that be for a ported box?
