Greets!
Not enough dimensions to tell how it might perform, though judging by the posted specs it doesn't look like something I'd want, at least without a lot of stuffing to damp it.

Simmed this one and it does need a lot of damping............

So I don't know which kind of enclosure suitable for this drive, which is the theoretically suitable enclosure box for this driver.
A 32.9 L [net] BR with a 5.07 cm^2 x ~1.9 cm [baffle thickness] long vent and damped to 'taste' seems a decent small cab compromise.
If ~2x larger TLs are an option, then up to 5-6 dB higher SPL down to around 30 Hz is a viable option.
