Two way speakers aren’t *that* hard to design. Three ways are far more likely to have wild impedance swings caused by too much overlap in the reactive components of the crossover themselves. You can typically avoid that using advanced crossover modeling….but one of the things that can be a challenge for any passive PA speaker is power handling. This is an area where DSP really begins to shine. For this speaker it’s still totally doable, and I’d be more worried about the drivers than the crossover components for distortion/compression…but too much more and even I’d give up on passive and go all active. (I have a 15”/1.4” combo on the way that is the absolute limit…and even then, I might consider going active with it.)
For this one I wanted to do a couple of things…one, make it pole mountable. Two, I wanted it to be a light as possible. This was for portable applications as a primary application, not install..so weight is pretty critical. Three I wanted it to sound good and have high sensitivity, so I was willing to give up a bit of bass extension........read more in pdf file.
