Crossover Filter & Equalization Network Design.

This page is for informational purposes only. Sorry.

Our extensive knowledge-base of filter techniques and technology comes from examination and repair of thousands of networks. Most networks are fairly simple, but some are rather clever, and it is from these that we learn. Once we determine what the filter curve should look like, our proprietary FilterDesigner (reverse iterative) software establishes the ideal component values. It predicts frequency response and input impedance (especially important if the network is complex). This makes it practical to compare several different ideas, and select the simplest, the most effective, or the most flexible candidate, before the building and listening begin.

We can produce custom networks or modify existing crossovers as your needs or system requirements change. We can produce safety filters to prevent damage if speaker systems are misapplied or mis-connected. Our circuit library includes networks to add 'sparkle' to dull tweeters, and circuits to adjust the midrange level of 2-way speakers, as if they were 3-ways. We can build notch filters to control troublesome output peaks, and we can protect speaker systems with up to four levels of protection to make them a lot harder to kill.
