anyone bi amp a pair of ess amt1d active xo ?

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!

Oh well, that's too bad. Enjoy them! Make sure the ESSs go to a good home.

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.
