When you decide to go active you might consider the following - http://rtaylor.sites.tru.ca/2013/06/25/ ... are-howto/ Linkwitz comments on Taylor's work - http://www.linkwitzlab.com/LX521/DSP_challenge.htm Richard Taylor's dsp crossover for Linkwitz Lx521 - http://rtaylor.sites.tru.ca/2013/03/20/ ... tware-dsp/ |

What size capacitors would you want to use? I'd like to jump into the pool. |

Where would we be without Parts Express? |

Sounds like a crossover party. I will bring a DSP one to try when it occurs. |

Tom Unless your system is voiced properly with passive crossover components, any comparison with active crossover would be moot point. In my experience, the capacitors in crossovers make a huge difference. I suspect, cheapest active crossover will do well compared to passive crossover with Dayton caps. |

If any of you are going to the DC HiFI Group meeting Sunday it will be there. Tom You mean Saturday, correct? Is the meeting moved to Maryland? |

They are horrible in any application yet you guys still insist on using them. Did you ever wonder why they are so damn cheap?! You can't judge the quality of those speakers with Daytons. I was going to hook you up with mil-spec polycarbonates similar to what I used in the B&W crossovers. You might have second thoughts about electronic crossovers if you do.

In my experience, the capacitors in crossovers make a huge difference. I suspect, cheapest active crossover will do well compared to passive crossover with Dayton caps. This is a subject for another thread but last year a few of the group did a double blind test of passive crossover caps at David Berning's house with some expensive caps there were rated very highly against some that were rated as worse than crap. No one could tell the difference in that test. Another thing is that using active eliminates the caps, inductors, and resistors. THere is nothing to get in the way between the amp and drivers. You can also do lots more like time alignment, etc with active. BTW, each driver in this system was individually measured and the values of the crossover components individually matched to the drivers. Tom |
