I'm always amazed at what kind of BS our SZ members can come up with. Speakers on keyboards are designed to sound good to the player's ears. Anyone who thinks two 10 watt speakers will fill a room with adequate sound for a party or whatever are dreaming. When one adds amplification and other speakers then the true sound of the keyboard come out. Keyboards and amps need to be EQ'd to meet the listener's ear. Everyone has a different deffinition of what sounds good. Some like Bose, Roland, QSC, etc. Don't expect miracles from under-powered systems.
