### 5/5 — Calculate to your hearts content!

*2020-03-17, version 1.0*

Got this to get the best out of my Hill M10 touring rig. Helps when I get to a venue and can tap in basic dimensions and roughly the response i’ll get from the speakers in the room, i can then do some angle options and work out the best degree slot to use my pins in. Much better than the previous spreadsheet type version.

### 5/5 — Great tool

*2020-03-11, version 1.0*

Great tool for system calculations with the Hill M10/M12

### 5/5 — Great app, just works well.

*2020-03-11, version 1.0*

Found this to be really useful in helping to find the best position for our speakers in which ever venue and also a chance to see what extra boxes would do for us.  
Great little app. Easy to use and straight forward.
