Good luck with your OB project!
Doesn't look like something I can use, since I need the 96dB efficiency with my 3-4wpc tube amp...
In spite of Mark's drawing skills, I still don't quite know what's going on. I THINK we have a 1mH inductor in series with the driver (creating a low-pass filter). I THINK a shelving network will have a resistor in parallel with the inductor to reduce its effect in the higher frequencies. Is that what this is? And I still don't know what a MOX is.
It is an inductor wired in parallel with a resistor. That combo is inserted in series with the positive lead of the B200 driver. That is all there is to it.
What I commented on was not subjective or degrading. What I commented on was the measured response curve of a driver. It simply has a response curve that requires a baffle step compensation circuit to balance. Once balanced it should have a sensitivity of close to 88db. There are no ifs, ands, or buts, about it. That's just the way it is.Now in an open baffle and with the compensation circuit it might sound great. I would expect it to sound great from what I have seen and heard about it. But, the top end is ragged and rolls off heavily. Just because I couldn't live with that top end doesn't mean others can't and it won't take away from how good it might sound in other ranges.
