bi amp imrpoving?

i mean to use one poweramp for the bass and one poweramp for hight and mid. it must be the active methode.

In that case, if properly implemented and adjusted, you can expect to hear significant improvement in practically all areas of sound.

If you intend to do active biamping, you must (1) bypass or remove the crossover built into the speakers and (2) implement a custom-designed line-level replacement for it. This is not trivial as off-the-shelf crossovers will not do but it has become easier lately due to computer-based modeling of speakers and crossovers.

The downside is that it is hard to get it right. Often negating any benefit it would have brought.

Amen. That is what I meant to imply.
