Question about bass management and crossovers

209.240.200.48

[ Follow Ups ] [ Post Followup ] [ Video Asylum ] [ FAQ ]

My Marantz receiver has a crossover of 100 when my speakers are set to "small". If I set the crossover on my sub to 70, will the speakers cross over to the sub at 100 or 70? Also, if they cross over at 70, am I missing a signal between 100 and 70 or not? All input is appreciated.

If you set your speakers to "small" on the Marantz receiver, the frequencies below the receiver's crossover (100Hz) will be sent to the subwoofer. All frequencies above 100Hz will be sent to the speakers. This isn't a hard crossover, as the frequencies are actually rolled-off above and below 100Hz.
Setting the subwoofer's crossover to 70Hz only impacts the signal sent to the subwoofer and not what is sent to the speakers by the receiver. Yes, in this case, you will lose some of the signal between 70Hz and 100Hz, as the signal will roll off past 70Hz depending on the sub's crossover. Any particular reason you want to do this?

  Since my speakers don't start to roll off until 45 hz I thought it might be fun to hear what my system sounds like if I crossed over lower. But if I'm going to be missing part of the signal no sense in doing that. Do you know anything about external crossovers like the Paradigm X-30? Would that help me in my bid to cross over lower without losing any of the signal? Thanks Michael.

    I used a Paradigm X-30 and found it to be quite useful. Using one to it's full capability generally requires a separate amp. That way you could send a full signal to the X-30, high-pass it at 50, 80 or 120Hz (in your case, 50Hz might work) to the amp driving you main speakers, and set an appropriate low-pass crossover for the sub.
    There is another way that might work for you. It is described by another poster here at AA:

    You might note that I responded to this thread and eventually tried the technique described in the post. I had reasonable success with it. I ended up with external amps, which was a better solution for me, so I no longer am applying this technique.
