DIY Line Arrays with a filter

[RaymondFromThePyrénéés]

How to go about with a DIY Line Array that I got from a friend for 70€.

There are 2wires, one for the mediums and the other for the tweeters
that has physical filters on the cable on each speaker column.

Can I wire both mediums and tweeters
with one stereo amp like the Ncore Hypex Audiophonics

or am I obliged to use additional amps
for the tweeters (this is what I did 5 years ago with 2x2 Alientek amps).

Thank you.

Without knowing anything about the actual "filters" it's hard to say. Sometimes a passive crossover has separate high-pass and low-pass filters but usually thy are "integrated" as one circuit.

It would be best to buy a known passive crossover (example) or an active crossover and separate amps for bi-amping.

Even with bi-amping it's a good idea to add a series capacitor to the tweeter (and to the midrange in a 3-way) to protect the tweeter from unexpected bass if/when something goes wrong. The series capacitor acts as a high-pass filter and it should be selected so it "kicks-in" at a lower frequency than the actual crossover so it doesn't interfere and only comes into play when something's wrong,

Thank you DVDdoug. So with this passiv crossover you sent me as attachment, I suppose I could use only one stereo amp like the 3E A7 for these speakers ?

Then for the sub, I believe the WiiM Ultra has a specific SUB outlet to where I must then ad an additional 3rd amp like the Fosi mono V3.
