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

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
That's funny - I am doing a biamp on my AMT 1Cs with that same crossover - Rane AC22. My amps are a Pioneer for the tweeters, and a Crown for the woofers.
Like you, I am also using a modern receiver for the pre-pro. In my case, a Denon 3808CI. What I did, with great results, was to the bias the crossover in favor of the woofers slightly to make sure the bass isn't lost, and then run Audyssey, which does a fantastic job of correcting the frequency response irregularities of the drivers, which the original crossovers took care of.
In your case, that's tough because you are trying to side by side them, which I can understand. But I found the results excellent. I am also using Audyssey XT, like your Integra.
Let me know what you think!
As you probably already know, Audyssey does a fantastic job of correcting speaker response in the room. In a way, it acts like an equalizer, except without many of the downsides of an EQ. It also corrects time delays, and other things.
Well, when you calibrate your system with Audyssey, it's meant for room modes, assuming your speakers are already close to flat. Well... if you speakers aren't flat, Audyssey still fixes it, within the limits of what it can correct. Try to get it as close as you can, while biasing it a little to the lower end (that's just my experience; yours may be different). Then run the full microphone calibration like you normally would. I think you'll be happy with the results. I know I am. :)
I'm curious what crossover point you settle on - I left it at 800Hz. Going in each direction has potential consequences, so I figured since ESS's active crossovers were 800Hz, I would leave well enough alone. But who knows - something better could be possible, though I would think a higher xover point would need something other than a 12" woofer.
I look forward to your results!
well the process has taken a u turn - i live next to a hifi shop and i should never go into it! This whole upgrade process opened my mind up to other options (or speakers) that i may be missing out on (having this set of AMT 1D's for 17 years) long story short - i purchased a set of martin logan vista's.
my experiment is over - sorry i could not supply you with any other info!!
try doing a +- swap on one driver....probably the tweeter.
IF the crossover phases ADD at the crossover point, it may be too much. If the original crossove was such that the speaker had to be wired in or out of phase to be correct, you may simply need to swap......
Example: my maggies have a 1st order hi pass / 2nd order lo pass. The 2 drivers are wired out of phase. Good even response thru the crossover region.
IF I swapped the tweeter, it simply wouldn't be or sound right.
