pc recording speaker recommendations needed

[robbocop]

At the moment i have altec lansing 621 speakers,one subwoofer and two shielded speakers either side of the monitor,handling mp3,s etc they are great,very tight bass and can handle most music till your ears bleed,but this is the fact i cant get hy head around,they buzz or seem to break up slightly on some bassier clean sound guitar notes?its really annoying,can anyone recommend two speakers i can use with my subwoofer,not too expensive,just ones that should handle any instrument comfortably at room volumes(whatever that is?),thanks!
