For all its worth who cares about internal speakers , they're all incapable of showing what your keyboard can really do. There's so many choices for outboard systems from super compact to full out I would keep the keyboard if you like it and look in that direction. My Casio PX350 sounds OK with its internal speakers but nothing like the sound from my Carvin practice PA. Just my opinion.
Hi Bill. I rely a lot on the onboard speakers for my kind of use. Mainly family rooms and small functions where I can just take out the board and start playing without any huge setup. Therefore if the speakers onboard the s970 sound the same as the s950 might as well not change. Thanks.
