With the Sony XS-FB1730 you listen to heavy bass tones. These speakers have a powerful MRC woofer in addition to a 35 mm tweeter. Connect the speakers to a Sony car stereo with the Mega Bass function and bring the deep bass of a dance, rock or hip hop song to life. Due to the peak power of 270 watts you listen to a powerful sound reproduction. The tweeter ensures that the treble, such as vocals and guitar lines, are not lost in the sound mix.
