Solutions for different SPL between speakers

[Pedroga]

I'm studying winISD and I noticed that when I compare two drivers in the same project in winISD in the sound pressure tab (SPL), the sound pressure disparity is reasonably large and I would like to know how to improve this... I looked here on the forum and some websites that the use of resistors to reduce the power that would go to the driver in order to equalize the volume between them is totally reprehensible as it considerably ruins the sound quality, another solution that I was reading about was crossovers (which is the one I think about most). I was thinking about the work that I could also use to use equalizers to send more bass signal, for example, to the subwoofer or even reduce the signals from the midranger and tweeter, but thinking about it I think that wouldn't be a very good solution.

An interesting first post, which is surely more about design principles? I’ve no idea what winISD is but I’m assuming it’s a tool to design speakers or crossovers.

Your hypothesis that resistors ruin sound quality will not get much traction with practically every speaker manufacturer, as the use of padding resistors is widespread. Leaving aside active speakers, maybe you’d like to explain why you think that?

AFAIK most crossovers not only divide the appropriate frequency range between the drivers, but regulate the relative levels.
