Joe, what amplifier do you have? If it doesn't have any DSP then it's not really an asset worth keeping.
Perhaps for classic rock and other genres from the '80s and beyond, for any modern music genre not so much. If you try to force heavy bass from them you will have the same problem you have now.. blown woofers.
Powered speakers are where it's at these days, these deliver far better sound and performance than passive simply because all the necessary processing and protection is built-in. For maximum portability a system comprised of a single 12" powered sub with a pair of 8+1 tops would easily outclass the passive speakers mentioned above.
