The Be diaphragms fall off much earlier compared to the rest. And the sensitivity reduction is not linear so it is a bit tricky to adjust.


Hence you need a lot of boost in the DSP to compensate for the UHF and even then it is diffucult to get the sparkles on top. That is pobably why JBL uses UHF with all Be designs.

I do the same and use 045's with Be both in VTX and M2 WG's. I just sounds better to me even if the BSS DSP can get close without the 045's. With SL diaphragms it is much easier to leave 045's out.
