Hello All,
Does annyone here have any experience or comments on the EC21 valve electronic crossover. If by some miracle someone had the crossover component values chart I would be grateful for a copy or link:applaud:

audio research is alive and well in plymouth minnesota and a trip to their website is a good place to start

a bit inconvenient, considering the time difference, but call 'em and
you'll probably talk to Leonard... or perhaps consult with a local dealer
(if feasible).
Often, there's useful info here (sort of a "fan" site):

Thanks Jim and Grumpy,
I have tried their website on the EC-21, but the info is not that detailed. I supppose a phone call in the dead of night or email is the way to go.

Hi Joe,
Email would be nice, but I don't believe they offer responding to email as
an option at this time... -grumpy

I am curious about the ARC EC-21.
The low pass is active and the hi pass is passive.
Slopes are either 6db or 18 db/octave.
Has anyone tried 18 db/octave on a 43xx monitor ?
I am thinking about using an EC-21 to biamp my pair of 4333b.
Opinions ?

Thanks Ian,
It's interesting you should say that. Trevor is a really nice guy-
Embarrassing story follows....
Many years ago Trevor was cleaning out some of his Audio Literature and came upon the EC21 crossover chart. He knew I had just got one and made sure he gave it to me. Then our renovations started... and that piece of paper has not been seen since-gobbled up into storage somewhere. I am sure it will turn up when I don't need it on my next clean out.
Thanks for the thought
Best
