Yamaha SW118IV : madman_isere's user review
I use the SW118 IV for 6 months in a double amplification configuration. The SW118 IV dlivre a nice bass, good quality sound trs. I add the wheels as to the weight and space this option s'avre trs useful. I recommend this product with a good pair of satellites.
