Post Subject: Adjust crossover-values?Posted by ayebee on: 1/11/2010

Hi Jessie!

I’m probably suggesting the obvious, but have you tried adjusting the crossover component values on the fundamentals and MF-channels? On the fundamentals-channel, increasing the inductor-value, and decreasing the cap, so that the slopes cross on the same frequency, but in a lower amplitude, could be one way to decrease the sensitivity without resorting to resistive attenuators.

The same could *perhaps* be applied on the MF-channel as well. When I changed the driver in my upper-bass horn, I could increase the cap on my JBL 2420 MF-driver from 3 (if I remember correctly) to 3.3 uF to match the increased sensitivity. This change actually affected sensitivity of the MF-channel more than it did affect tonality.

Of course, this is just another way to burn sensitivity, so that particular headache is still not cured.

Could you perhaps post a schematic of your current crossover?
