Link to a neat little sight to help you figure componnet values for that DIY crossover upgrade. The crossover is fundamentally one of the most important (often overlooked) elements in a speakers design. Most manufactueres (including Axiom) use cheap components in the crossover design and upgrading to better higher quality componnets of the same values (you'd be amazed) can drastically improve the sound of an already good sounding speaker. Keep in mind to never do anything you aren't comfortable with...its your investment!
