    Hello all,

    I have just bougth a very cheap kenwood home theater receiver.
    It's a krf-v5060d.
    It has a pre out for hooking up an active subwoofer.
    The specs for this output are.
    output level 1.5 V
    impedantie 2.2 kOhm

    I do not have an active subwoofer but I do have very powerfull speakers
    (8ohm nominal input) and a hifi amplifier with input for tuner, tape, aux
    and phono.

    What can I do to fabricate a subwoofer with the amplifier and the speaker?
    Which input should I use? Do I need something else?

    Thank you

    Are you saying you have 1 or more other speakers than your "very powerful speakers"? Or are you asking if you can use the other amplifier with your "very powerful" main speakers?

    If you have a suitable woofer you can build a cabinet for it and use the sub output on the Kenwood to drive this home brew subwoofer powered by the other amp.

    If you are thinking of using your "very powerful speakers as a subwoofer using the sub out and the other amp to drive this "subwoofer", that won't work. You can't drive the same speaker from 2 different amps, that would kill both amps.

    Unless you are a real do it yourselfer, save up till you can afford a good sub.

    Arthur and others,

    Here is the complete situation.

    I use the kenwood receiver in its 6 channel mode.
    So i have.

    Front main L and R (RCF monitor 8 300 W)
    Center (Monitor 5 175 W)
    Surround L and R (Monitor 5 175 W)

    After testing a bit with a film I'm missing the deep rumble
    bas effects so I tried to hook up a (RCF monitor 8 300 W) as
    dedicated subwoofer. I have no test CD but there is a test signal in the receiver with I think some white noise.

    If I test the sub pre out on the dedicated pioneer Hifi Amp
    I found out that I can only uise the Phono input to create the effect I'm looking for. I know the phono input is very sensitive but I tried it because I get almost no signal on the other inputs. ( tuner, aux and tape).

    Should I use an pre-amp to pump up the signal?
    Is this normal?
    The specs for this output are.
    output level 1.5 V
    impedantie 2.2 kOhm

    Thank you,

    So if I understand correctly you are trying to use your main speaker(s) both as mains and as a sub.

    In most cases, this does not work. If your Kenwood has pre-outs and main-ins you could use a graphic equalizer to boost only the bottom octave. I'm not familiar with that Kenwood model but my guess is it does not have the pre-outs and main-ins. So you are essentially limited to what you can do with your tone controls.

    Others may have ideas for you. I think you need a sub. Perhaps you could find an unpowered sub and use your amp for that.
