When you gotta have big piano performance in a small package, you gotta have Kawai's new ESX Portable Digital Piano.  Great sounds, combined with a weighted-hammer action and a powerful built-in speaker system, make the ESX one strong performer. Place all this power into a package weighing in at a mere 40 lbs., and you've got the perfect portable piano for any gig, rehearsal or personal studio.
TONE
The ESX uses our critically acclaimed Harmonic Imaging sound technology... the same technology used in our award-winning MP9000 Professional Stage Piano.  Harmonic Imaging creates an acoustic piano sound of remarkable depth, expression and realism.
You'll also be impressed with the other ESX sounds... Strings, Electric Pianos and Organs. 16 sounds in all.  And, any two sounds can be layered together in a DUAL mode.
TOUCH
Kawai's new Advanced Hammer Action II brings the feel of a real grand piano to the ESX.  Its weighted hammer action design offers superb response and a smooth feel that will satisfy the needs of professionals and educators alike.
SOUND SYSTEM
The sound system of the ESX uses an innovative design in which the stereo speakers face out from the rear panel toward the audience or classroom.  A port system releases sound from the top panel toward the player.  This unique system delivers a surprising amount of sound volume while creating a natural sound for the player.  The EQ feature allows you to adjust the sound quality to match the room that you are playing in.
SIDE PANEL
A variety of useful connection jacks are conveniently located on the side panel of the ESX.  Two headphone jacks are provided for private listening.  Left and Right Outs and a Stereo Line In provide all necessary audio connections.  The ESX has a PC interface jack for direct connection to a personal computer and MIDI In/Out for connection to other musical devices.  The pedal jack is compatible with an optional F-2r foot pedal (2 pedals- Damper and Solo).  Additionally, the internal speakers can be switched off when playing the ESX with an external speaker system.
