Simple easy question about the Maggie XO-1

75.40.88.161

Does the XO-1 make the factory crossovers unnecessary?

Also, anyone doing horizontal bi-amping ? As in, one stereo amp for Left speaker and one stereo amp for right speaker?

Thanks

is a PoS.

If you want to bi-amp - do it properly ... with an active XO.

And re. " one stereo amp for Left speaker and one stereo amp for right speaker " ... I agree with Grant - that's actually vertically bi-amping! :-))

But, as I had 3-way Maggies, I was using a stereo amp on the mids & ribbons plus a monobloc on the bass panels - each side.

  Thanks. Which budget active XO would recommend?

        As I did.
        
        So you can run them:
        * active 2-way - in which case:
        ** a 4-way active XO would suffice - like the miniDSP 2x4HD
        ** and 2x stereo amps.
        
        * or active 3-way - in which case:
        ** you need a 6-way active XO - like the miniDSP 10x10HD (which is what I had)
        ** and a total of 6 amplifier channels.
        
        Or you can use analogue active XOs - but they don't give you the very useful features that digital XOs have.

Thanks!!!!!

Maybe these diagrams will clarify the issue for you.
1) The XO-1 has a high pass filter which takes care of the treble but the "bass output" is actually the full signal and it needs to be directed through the speaker's low pass filter.

2) The difference between vertical and horizontal biamping is illustrated here:
Vertical:

Horizontal:

And 3) Vertical biamping using an XO-1:

I think if going that route an active xover is a better option.
I am vertically bi-amping (one amp for left, one amp for right) on my 3.6's... (horizontal is one for tweets/mids, one for bass).

No. Remember the XO-1 is only two potentiometers for the low pass section and two capacitors of choice for cutting off the lows from the high pass section.

I have a stereo amp behind each MG 3.6, feed by an active crossover.

  Thanks. Does the XO-1 separate line-in signal into Bass and MidTr? If yes, that should suffice to amplify and send directly to appropriate terminals on each speaker. Please explain like I am 5. Lol.

    No, it does not. What model of Magnepan are you using?
    
    Here a few pictures of the XO-1:
    
    If you solder in a suitable capacitor it will replace the speaker level crossover for the high pass section. The potentiometers in there will allow you to set the level on the low pass section, which still require the speaker level crossover.
    
    With the MG 3.6, the XO-1 is only replacing the yellow capacitors in the outboard crossover. You will still need the rest of the components.
