Bases on your other post below, I am assuming 1.6QRs.I am biamping these with a Rane xo which is 24 db/octave and I have the xover point set around 550-600 Hz.
The Maggies never sounded better. Of course you need to reverse the phase of the tweeter with this configuration (putting the tweeter in phase with the bass panel).

Could you explain that part again about putting tweeter in phase with the bass panel when using active crossover? Thanks, Tom
In the stock passive xover configuration, the tweeter is wired out of phase with the bass/mid panel in the stock design. This is because the bass/mid slope is 12 db/octave.If you eliminate the passive xo and go active like I did with a 24 db/octave active XO, the drivers need to be wired in phase. All that is required is reversing the tweeter polarity.
I will never go back to stock slopes or passive xovers on my Maggies. It simply makes them sound much more transparent and quick, more like electrostatics than before.
I`m very glad you told me this! I love music but not very skilled in electronics. I agree, the 1.6`s never sounded as good as they do with an active X over. Even a cheap one like mine. ( hope to upgrade soon )So all that is involved is reversing the original hookup wires to the tweeter, correct?
