Probably won't make that much of a difference compared with completely rewiring the speakers with various gauges of OFC cryoed copper wire, using copper binding posts, bypassing the fuses, upgrading the stands buying Mye's, and then building an entirely new external crossover out of very high quality parts.
Any of these things, especially the speaker stands, might be a better option. Bypassing the fuses is not to be done if you drive the speakers hard.
