As others have noted already, without enclosure parameters, it is hard to say much.

However, from what it looks like, the Devine driver is primarily a PA Woofer (W-shaped surround, paper cone, 8 Ohm impedance are all indicators), and won’t work well as a subwoofer, as that’s probably deeper frequencies than it is designed for. Maximum excursion would also probably be very limited as is usually the case with W-shaped surrounds.

So considering you are looking for “bass” and putting it in a subwoofer enclosure, I’d argue that no matter the enclosure, the Devine BA12 is not suitable for that.

The measurements I currently have for my box: https://www.pinterest.co.uk/pin/audio-in-2023--209347082672576066/ Note that mine has a 12" driver hole, not 14" Rest of the measurements are correct

We or you need to know internal dimensions of the enclosure and if it’s ported, horn loaded, sealed, etcetera.

Only then will you know spec scope of an appropriate driver.

hey, you should consider the internal dimensions of the enclosure and if it’s ported, horn loaded, sealed, etcetera to know the spec scope of an appropriate driver. Only then will you know which driver will work best for your setup.

Grs 12SW-4HE is a surprisingly capable subwoofer for $60 on parts express. Check it out and model it in your box to see how it will do.
