    Does anyone have a list of pre/pros, or receivers, that provide variable LFE/Bass crossover settings for each channel?

    In terms of being able to sum low-pass bass:

    Lexicon DC-1, DC-2, MC-1, MC-12, MC-12B (soon to be released MC-8 and MC-8B)
    Outlaw 950

    I also believe that some of the Sony processors and receivers can (sorry, I don't know the exact model numbers).

    Theta Processors have the best bass management options. Extremely flexible.

    The Sony TA-9000ES, a bit long in the tooth, but it too has flexible bass management, including a high cut LFE with its version 2.01 firmware upgrade.

    You can do just about anything with the Theta's.

    You can chose between three diff. types of crossovers; phase perfect, butterworth and linkwitz-riley. Which ever one you chose applies to all channels, but for each channel you can set an independant crossover frequency, slope, and phase. So you can pretty much chose a point between 40HZ to 160Hz and a slope between 6dB to 24dB.

    Sub is flexible as well, you can send it a crossed over signal or a full range LFE signal.

    This applies to both the Casablanca I and II as well as the lesser priced Casa Nova which I have.

    Of course the Casablanca II takes it even further with 12 channels of pre-amplification, of which I think 3-5 can be subwoofers.

    Thanks to those who have responded to my inquiry. I'm a little surprised though that there are not whole lot of these types units available. I would think that this type of flexibility would be very popular. Based on what I have found in my searches and what I see here though, that doesn't seem to be the case.

    Are most people concerned with the latest and greatest sound formats and features and just go with the standard 80Hz or so crossover?

    The Outlaw Audio 950 uses a Cirrus Triple Crossover for Front, Center and Surround speakers. You can scroll through the crossover settings to set the crossover point to 40Hz, 60Hz, 80Hz, 100Hz, 120Hz and 150Hz.

    I know that the Aragon Soundstage (?), not the current one, but the previous rev, had very flexible BM. You could set it separately for DVD vs 2 channel audio. But I can't remember the details.

    I agree, I don't know why flexible BM isn't more common. I had a Sony TA-E9000ES for 4 years. I now have the Outlaw. One of the big reasons was "individual" crossovers, and BM on the analog 5.1 inputs.

    BTW, over on Outlaw's site, they specifically pointed out in one of the threads, that the 950 indeed uses individual high pass and low pass filters on each "set" of speakers. No global low pass for the info crossed over from the mains. So the Secrets article is not correct in terms of any "hole" being produced by the 950. In fact, and this has always bugged me about that article, Brian does not name one receiver or pre/pro that *does* have that problem...


    On a side note, I'm still awaitin' for any news of the successor to the Sony, the oft-rumored TA-E10ES... [​IMG]

    Fosgate/Audionics FAP T-1. Adjustable frequency fixed slope crossovers for mains, center, surrounds.

    And...a 5.1 Ch analog bypass with analog Bass Management, fixed slope, 80 Hz. This bypasses the A/D-DSP-D/A completely. Great for SACD, etc.

    Yeah, would be nice to be able to pick the slopes too.
