Glenn...
I used the Altec Lansing system in retirement homes for about 6 months and it was ok...but jusk ok. It sure beat setting up my big amp and speakers. Then, I ran across a Sampson E-20 powered speaker which wires directly out of the keyboard. Much better. It weighs about 37 lbs and has only one input, but it is all that is needed for smaller rooms and audiences.
