Those speakers have a sensitivity of 90 dB. Which translates to about 97 dB at 5 meters with the amp cranked all the way up.
For me, it would be enough. My normal listening level would pull about 15 watts from that amp.

Thanks @Branson4020! I've been searching around and some people said that Polk RTI-a9 needs a lot of power, some said it'd need ~200 power per channel !!! I really want to audition them, however, I can't find any place near me. (Austin, TX)
