Better but mine unit came with dust inside the coil of the right speaker, this is normal on coaxial drivers where there is no dustcap to prevent dust getting inside the coil. the noise can be heard on low frequencies below its tuned frequency, my guesses are 70Hz. guessing because I don't have measurement equipment and the manufacturer doesn't provide a frequency response chart. neat that the speakers have ferrofluid to damp them and for heat dissipaation. Background noise is present but not high enough to be noticed. overall they sound ok but not fancy sound on lows.
