L-Acoustics K2 system supported by KS28 subs was used for Corporate Live event this year.
Last year, KARA with SB18 was used as a main PA system for the show.
As there were few live bands it was really important to feel a good ‘‘punch’’ from low end on the end of the venue all the way around. So, to achieve this I decided that the main PA system this time has to be changed from KARA and SB18 to K2 system and KS28 subs.
My choice was 6 x K2 plus 3 x KARA as an under hang per side.
16 x KS28 were designed to put on the middle above the stage to achieve true 360 degrees coverage.
In order to get some cancellation on stage I decided to split system into two arrays as shown below
And here is the sub mapping from 40 to 60Hz. This configuration makes cancellation both ways: on the bottom and top of the sub array, which reduce energy on stage, same as also helps to reduce reflections from the roof.
Here are the measurements I’ve done (purple line is sub summation in the audience, blue line is subs cancellation on the middle of the stage.
As a front I’ve used 108P speaker boxes in white colour.
And the final result:
