I am in the process of making external crossovers for my new maggies and was wondering what difference in sound I would have if I use active electronic crossovers? |

I've not met anyone that thought systems using active crossovers sounded worse than passive. |

He says he will save power from the amp, which is true but doesnt bothor me there really isnt but in the sound department ecccept being louder becuase its like a direct route to the speakers in stead of going threw the copper coils Allso there more for concerts and movies from what i heard |

Gold Member Username: Frank_abelaBerkshire UK Post Number: 1826 Registered: Sep-04 | My understanding is that in theory, active crossovers typically have about 10 times less distortion than the higher powered passive crossovers required to drive the same speakers. However, I've heard active systems on a few occasions (not recently I admit), and I have always found that the cost/performance ratio doesn't stack up. i.e. if you have 2 stereo amplifiers to drive the two sections of the speaker and add in the cost of the active crossover, is this a better result than one better amplifier into passive crossovers into the same speakers? Very often I find that the passive solution is better. I can only assume that this is because the weaknesses of the 2 less capable amplifiers are a worse problem to have than the weaknesses of the passive crossovers. Regards, Frank. |

Of course the DEQX does much much more than that, but still, its pretty neat stuff. Of course their 2.1 system is 6k, but thats with everything. It is on my short list to audition. |
