    Hello to every one in this forum, since last December this are the components of my home theater:


    Receiver: Pioneer VSX-D710S
    Speakers: Sony: SAVE-325
    Subwoofer: Sony SAWM40
    DVD Player: Panasonic DVD-RV30
    And a 4:3 CRT 29” Samsung tv

    I have the main speakers connected to the level input of de SAVE´s subwoofer and from there to my front left and right output of my receiver, the wm40 is connected by the subwoofer pre out of the 710 and all my speakers are set as small.

    Well this is my problem, I have recently downloaded the NCH tone generator to make some test on my subwoofer (Just wanted to know if there was any frequency disappearing because I doesn’t have an spl meter yet) and see how the crossover was working, so I connected my computer to an analogical A/V input and run my tests from there, the tests for the subwoofer were fine, all the frequencies were present but not at the same level and after a while I find why, the crossover wasn’t working at all, it doesn’t matter what was the value of the crossover, the tones were always in the wma40 and in the front speakers. After that I connected the main speakers to the level inputs of the wam40, configure them as large, and turned off the subwoofer in the receiver setup, I run the tones again but playing with the sub crossover and this time it works in the opposite way, the tones disappeared from the sub but not from the speakers, I don’t know what is happening, Does my receiver has a problem with the crossover or there is something that I made wrong?, Why is the sub crossover letting frequencies go to the speakers?, can you also recommend me which of the two speakers arrangements that I have described will work better. I will appreciate any help you could give me thanks.[​IMG]

    Yes, as the level inputs of the sub are supposed to be filtered letting high frequencies in the speakers an low frequencies in the subwoofer, I supposed connecting it that way will make an improvement in my speakers.

    Any way the save´s sub is only getting the low frequencies of the main speakers and no LFE or the low frequencies of the other speakers, that is the work of the sawm40 (or at least that’s what I intended), do you think that this could be the reason of my problem?
