In most cases, the speaker is not the problem, it is the amp!!! If you take an amp rated at 30 watts RMS and try to play speakers with a sensitivity rating of 89 dB very loud, the amp will start clipping and distorting. However, if you take the same amp and hook it up to speakers rated at 98 db, it will hurt your ears with clean undistorted sound. The key relationsip is matiching amp output to speaker sensitivity if you want clean undistorted sound at high dB levels.
