EQing dodgy speakers is a bit of an art.
And one most people are bad at and frequently know they are bad at. This would be the attraction of an app that has built-in presets for so many existing headphones and speakers. :-)
First wrong thing most people do is boost highs and/or lows. This is the wrong thing to do mostly because it robs dynamic range. The correct thing to do is reduce the unwanted band, usually around 4kHz range because that's where our ears are the most sensitive and thus where speaker drivers frequently peak.
I'm a little surprised your JBL towers needed some adjustment.
