Default would the Eminator 1508 make a decent big boombox woofer?

I have a few speakers which could be employed including 10" coax, 8" coax, 8" and 10" fullrange, but in my pile are some 1508 Eminators

a cabinet might be in the two cubic foot internal volume region/ 3/8" Baltic birch with a TPA3116

opinions and suggestions on tunings/volumes are welcome if you think it would make the foundation of a good sounding sensitive boombox

any bites? a small waveguide and compression driver could do the treble work - maybe a WG loaded dome - - not sure if a piezo would be worth the trouble but could save money

Two cubic foot = 56.6 liter, much larger than 21.7 liter cabinet simulated.
