I tried out a friends L1 Classic with two B1's.
I was so impressed with the sound I bought what I thought and was led to believe the same system, but what I was sold was an L1 Model 1 with two B1's.
I had some problems with the sound fading (limiting) and you can read them here
set up for larger venues
only on further investigation did I realise that they have two different outputs ie; the classic gives a total of 750 watts where as the Model 1 gives a total of 500 watts.
There is supposed to be no difference in audible volume between both systems however I find that there is a remarkable increase in volume before the Classic system starts to limit.
I have now swapped the L1 Model 1 for the older Classic model and I am getting the results I longed for with no limiting.
