Thats what i dont understand diki. I own the PAx and it weighs slightly less than the E80 but the speaker system is simply outstanding. Why build a keyboard as heavy as the E80 with built in speakers that sound so poor that you cant even justify the extra weight with its purchase ?

AS an aside, for the scarcity of time that i have in my busy life to play the instrument and the way that i have to grab moments to rehearse with choirs and small vocal groups, plus the fact that i take my 7 year old daughter every where with me , there is just no way that i would ever buy a keyboard that did not have built in speakers. For large venues play direct through the church pa system or an amp but why would i want the extra hassle when i just needed to grab a 30 minute practise with a group or if i had to move to another room because of shortage of space ?

Never mind the times when i feel inspired just before bedtime and want to get something recorded on the sequencer to expand upon in the morning ! For me built in speakers are esential.
