MG1.6 crossover upgrade merits.

The MG1.6 has a simple crossover, two capacitors (one multi-element because of value) and an inductor. It is a good candidate for upgrade with top quality components, eg:musiccaps and aircoil inductor. These widgets aren't cheap! It will set me back about $200 to do one speaker, and I have three to do.

The components in the original crossover are not bad: Solen foil caps.

What is the opinion out there regarding whether such a crossover upgrade will yield improved performance. What will be different after the change? Has anyone done it?
