Loud and Heavy. 
If you would like to play the Taiko-1 with traditional Taiko drums, I, Ringtaro recommend you to choose this PM-200.
 
Delivering rich, dynamic sound in a streamlined package, the PM-200 is the ultimate monitoring solution for Roland’s V-Drums. Packing 180 watts of power, the PM-200 features a custom full-range speaker system and rugged cabinet specially optimized for reproducing the famously expressive V-Drums sound and response. And with integrated mixing and direct output capabilities, it’s easy to interface with other devices at home or on stage.
