Often these mainstream music recordings (radio songs, top 40, etc.) are not "poorly" recorded per se.
The quality of these recordings can actually be considered quite phenomenal, however the sound editors typically enhance certain frequencies in the music before it becomes stamped onto 10 million copies of Brittany Spears Best of editions. This is done so that the most common listeners that playback the music on relatively 'poor' quality systems (boomboxes, standard car stereos) will hear a perceived better overall effect. Those enhanced frequencies tend to correspond to high treble and heavy bass which is why alot of pop music can kill your ears with the bright style of Axiom speakers. (One of the loudest i've heard to date is a song called Summertime by the Sundays.) This practice is more intentional as opposed to incompetence in studio recordings.
duong,
If you are looking for a less bright sound, the M3s, M40 and M50 line should be better for your tastes but if you are not sure it will be enough, then trial the 30d with the M3s first.
Otherwise you should possibly consider an even more laid back, alternate brand of speaker.
General opinions have reported these new fangled Rockets speakers have a very 'dulled' upper end but are quite decent for their price.
