the Qts says that a ported box is not suitable. Choice of sealed box or infinite baffle. The high Fs when loaded by a sealed box will rise even higher. This will require enormous EQ to get decent bass response and unattainable EQ to get sub-bass response. But look at Xmax. This is too low for good bass. You are struggling with this driver in a sealed box.
A set of them in an infinite baffle may work with a bit of EQ to bring the bass response up, but forget sub-bass duty.
