I have a pair of ALS originals (ALS-I), 2 M1.5ts, and a DBX-223 active crossover.
I have read through a few of the "Active Crossover" threads and have not seen where a modifier has added series resistors to the Ribbons or Woofers to present an acceptable load to the driver amps.
My questions for ALS original owners who have removed the passive crossover and replaced with an active crossover.
Did you add high wattage resistors in series?
To the ribbon's positive lead wire?
And/or the woofer's positive lead wire?
