Sorry to derail the thread slightly, but while we have PA bods attention can I ask another question? I run the PA at church (qumix 32 + HK audio Elements system). The Elements system suits what we need just fine for downstairs but the balcony is raked seating and the elements have a super tight dispersion. When you are sitting in the line of fire then it is all good, but if you are higher up the tiers then the detail gets lost. I am thinking of putting in some standard plastic boxes for upstairs with a broader hf dispersion. They do not need to be beefy because the HK subs will do the heavy lifting and I presume that I can do an HPF and a slight delay on seperate outs on the qumix (cos it does everything else). Can anyone suggest a suitable cab?
