Phase: with ads 1230, only the ads 2000 biamp crossover will work.
. This is because the internal and ads 2000 crossovers do something to the phase of the woofer . I used an external analog crossover and had some big holes in the freq response as evidenced by using an audessey rc equpped reciever .
I think the culprit was a woofer that was out of phase by 90 degrees.
I thought about triamping my Valkeryie speakers which scream to be triamped but to do it actively would require some serious surgery so I’ll likely “ dumb” Triamp thrm ( passive) and use an old av receiver .
