Look for a sub with a good bit of power. You shouldn't have much trouble matching sub to loudspeaker. The problem is finding subs that sound good for music if this maters to you as it does me.
I agree with Johnk that finding a sub that will match level-wise isn't going to be difficult. Subs typically have built-in amplifiers that have lot of gain, so the actual electrical efficiency of the woofer isn't an issue because they're designed to level-match with a wide variety of speaker systems. If in doubt, tell the sub manufacturer what you plan to do and ask for his opinion.
its depends on speakers if they are fragile paper cones 88db which can handle 20wats i would dsay no diference. but if they are able to take some power ,practicaly most subs will fail/burn/smoke/crackle. in the second case i would look for sub with no less than 115db/30hz. also keep in mind that dicortions in lower range is less noticebale but at hefty levels(which are needed for 83-86db subs) most subs have 10%-15% discortions which is realy too much.
