A7 Active Crossover Choices
My clone A7's are completed. 416z's, GPA 902's, 511b's. A pair of subwoofers starts working at 60hz.
Active Crossover time. My application is home hifi. Classical music.
I tried a search here, but the site doesn't respond.
Currently I'm using a pair of singled ended amps with frequency division via a minidsp 2x4HD. Plenty loud in my large high ceiling room.
Lots of slopes to choose from. 6, 12, 18, 24, 48. Butterworth and Linkwitz Reilly are both available. Also lots of capability to perform room and driver correction. And variable delay for each driver.
First up, frequency and slope choices. I'm presently using second order Butterworth at 800 Hz. It sounds pretty good. I've also tried LR 24db slopes.
What are others using in the active realm?
Thanks for any input.
