Excursion is how far back and forth the driver must move....every driver has a limitation, as you approach those limitations you increase "strain" on the speaker, probably a very generic way of putting it but, as the driver reaches its limitations its performance degrades, in a nutshell. A 15" vs a 4" to produce 100hz at 90db....the 15" is going to move back n forth a shorter distance to produce a matching signal to the 4"....the large diaphragm of the 15" creates a higher pressure within a shorter amount of travel. If we start adding more drivers to team 4", say nine 4" drivers vs the one 15".....now the group 4" has surface area more resembling the 15" so the cones of each 4" will move much less....pluses and minus's are all over the place but the main goal, lowering excursion...on the opposite side of what happens when you push the driver to the limits you have a driver whos staying very close to its middle....its happy place? The place where the system has the most control over the cone?
The same philosophy can be applied towards amplification...you want your amps to easily cover power duties.

Most proaudio amps have input attenuation controls on the front panel.
Alot have sensitivity or gain setting switches of the back panel.
Many newer DSP amps have both input and output levels available.
Bottom line with any of those settings, is turn the amp down so that you can run the line level signal high, but without any chance of clipping.
(line level clipping is a much bigger No-No than amp clipping)
I have those settings within the input dsp card....this info going straight into my notes, ty so much.
This is what I don't get and would love to know why?
I take in consideration most of the speaker design parameters, enclosure, baffle edge diffraction, proper crossover points,, ensuring each drivers frequency response bandwidth, make sure it has descent group delay understand beaming at what frequencies, have a multichannel DAC that measures really well and use DSP to flatten out the frequency curve and improve impulse response and the end result still could be a failure? But isn't that with any speaker design?
What is it exactly with active crossovers that you need luck with? Is it that its just harder? Or just that there is more ways to voice a speaker with passive crossover? There must be something that many say take an existing design but they went about the same way to design that speaker albeit significantly more professional and with more experience.
Or are you just saying that there is a chance that it won't be the perfect speaker that you were expecting?
Anyway, looking forward to your response!🙂
