A bandpass box may produce good results, while keeping excursion under control.

For example, Vsealed=40 litres, Vported=32 litres, Fb=58~67 Hz (depends on whether or not you use an active 80 Hz@12dB/oct filter with it). The result should be a "subwoofer" (-3dB@35Hz) which should be good enough for HT use.

An alternative is a 6th order BP enclosure, but I don't recommend going this route unless you've measured the t/s params of that driver, and you've got an SPL meter to help you fine-tune the design.
