Hi all!
I'm currently designing a speaker based on the Neo3 PDR and the Dayton RS150. So far, the only real problem I've had is measuring the Neo3 (I don't know why, but it has been a bit hard to get a good, smooth measurement with it).
Anyway, I'm now confident that I've good measurements of both drivers, and I'm starting to design a crossover for them. I thought about building a standard 4th order acoustical filter, with a third order electrical on the tweeter and a second order electrical on the woofer.
Then, I found out that a third order electrical plus a conjugate on the tweeter and a second order plus a parallel notch filter and a conjugate on the woofer could get me an 8th order acoustical L-R crossover.
I'm quite curious about it, since I'm always worried that I may be overdriving the tweeter, even with a 4th order. One thing I've noticed is that minimal variations on the components causes a big effect on the overall frequency response.
So, besides rolling off the drivers quicker, are there any advantages of using higher order crossovers? Off axis response seems similar to me... anything else I should know?
