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

How'd it go? BTW, you will need to use it on 'stereo' mode or another mode where Audyssey is active for best effect.

Thanks IBJAMON!!
I have not got there yet.
Still working the side by side audio comparison.
Thought to adjust the Q using the Rane by using both channels (one for low) & (one for high)this would enable 2 points of adjustment using 2 XO points.
Still dorking with it and will supply an update soon!
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!

Any luck with this? I don't assume that my setup is perfect but it gets the job done... I'm curious if you found something better.

Thanks,

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!!

Take care!
