[QUOTE="genxx, post: 3072385, member: 575023"] Desertheat-He wants to run active-I now the set he is using has the DRT-25 which needs to be crossed over no lower than about 2.5khz and up. Looking at the manual it apppears there is a 3x mulitplier on the HP filter on the front channels bringing it to 1800hz and up. Is that correct. Which is not going to get work with the DRT-25 tweeter's. I would say they might play that low with a steeper slope but its risky. This from the manual on the A4 The filter setup are as follows: Front:Lowpass (LP) 50 - 125 Hz Highpass (HP) 20 - 200 Hz alt 60 - 600 Hz (x 3 button) Rear: Lowpass (LP) 45 - 200 Hz alt. 90 - 400 Hz (x 2 button) Highpass (HP) 20 - 200 Hz The x2 and x3 buttons are used if you run a 2-way I am not pulling for either amp in particular. Can we help this guy out in what will get him active 2-way front off the amp x-overs. I will try and find the manual for the ARC.
