anyone bi amp a pair of ess amt1d active xo ?

neck deep in this project.
Using a rane AC22 active crossover
2 X ADCOM 5400
Integra 7.8 pre out

A/B - ing both speakers (one standard using the ess passive xo the other using the Rane xo set to 800hz) i find the mid and mid highs harsh. tweaking the xo point up to 900/1000/1100/1200 did not help much.

Any help via experience would be great!!

Thanks

What slope are you using? What are the passive crossover specs for that model?

The Rane xo has a 24bd slope.
I have tried to get specs from Ricky at ESS but no deal!
The ESS crossover has the heil at 800hz.

thanks for the response!!

The slope may be to steep. I'm not familiar with the Rane other than i have seen a picture. I would say your ESS would have a slope at 12db/octave and the slope would finish around 800hz not begin at 800hz
The woofer would also phase out completely around 800hz at 12db. You may need to start your slopes around 650-700hz for a smoother transition at 12db
