I agree that getting different speakers is a great option, but if someone wanted to keep these speakers I don’t see any other option than EQ. And, if the off axis response is a smooth mirror of the on-axis response the results will sound excellent. I doubt that’s the case with this speaker but an equalizer can be a great thing if properly applied, doing far more audible good than harm. It’s more like putting shoes on your feet for a walk in the woods than a band-aid. It doesn’t just fix errors. It opens up new possibilities. Without filters much less would be possible in audio. For one thing we'd be stuck with whatever a full range driver could do. Or we'd just have to come up with drivers that roll off correctly on both ends of their ranges without any crossovers and somehow sum correctly. I think crossovers are great in speakers, and I don't consider them a band-aid. If I want to modify the response I'm just modifying the crossover.
