Most of my time at home when playing my Arranger Keyboards is using Headphones, you spend a lot of time getting everything to sound great.

But when I go to nursing homes etc I use the Keyboards Speaker System, most of these venues are quite small, get in setup and play not alot of time for sound checks.

So how do you get the best sound from your internal speakers.

Most arrangers have some form of a Master / Global Eq system which will have some presets, but if you want to do things off your own back learning which frequencies do what and do you know when to boost or cut?
