What do these freq response and xover specs mean?
I think what they mean is that it will put out 36Hz -120 Hz, +/- 3dB.
Outside if this range, the output might vary more than +/- 3dB. This is rather confusing. ~James. ) "hoarse with no name" wrote in message ... http://www.velodyne.com/velodyne/pro...ecs/VX-10.html "Crossover: Variable from 50-200 Hz Frequency Response: 36-120 Hz, +/- 3dB" Does frequency response mean the possible frequency range? If so, then why would the variable crossover allow you to choose a crossover point higher than the highest frequency in the frequency response figures? |

And you will simply be rolling off the higher response slope even further with the crossover, dependant on its setting. This is rather confusing. Not at all. Why do you think so? MrT. |

I believe this means that they bought their amplifier/crossover subassembly from outside, and this one was the cheapest. It wsould have cost money to change the crossover limits, so they didn't bother. d |

In HT applications, you can use the processor's crossover setting (usually 80 Hz), and then set the subwoofer's to '200 Hz' so it's 'out of the way' |

Gary,
In HT applications, you can use the processor's crossover setting (usually 80 Hz), and then set the subwoofer's to '200 Hz' so it's 'out of the way' That explanation gets my vote too. And that's how my Carver Sunfire sub is set up. --Ethan |

In article , "Gary Vander Schel" wrote: In HT applications, you can use the processor's crossover setting (usually 80 Hz), and then set the subwoofer's to '200 Hz' so it's 'out of the way' Are you saying that since crossovers often alter the sound near the crossover freq the maker allows you to set the crossover freq so high that what is played is completely out of the range which is altered by the crossover circuitry? If you are using an active subwoofer in a home theater application, then typically the receiver's crossover is utilized (not the crossover on the subwoofer). In order to 'disable' the crossover on the subwoofer, you simply set it to it's highest setting (in this case, 200Hz). If you are using the subwoofer in a different setup, e.g., two-channel, for additional bass extension, then you would set the subwoofer's crossover based on the low-end response of your main speakers. |
