Default Help on Heco Cantata 550 tweeter tweak

Hello!

I have a pair of Heco Cantata 550 that came without tweeters. As well i have a pair of Heco Allegro 350. For choice I have a Philips 8 ohm AD11600 tweeter for the cantata but original is 4 ohm. The tweeter could use a little boost so I would have to remove a resistor from the pcb of the XO. WOnder witch one? Thank you! In the pictures the tweeter gets out + and - at top left.

It would be better to reverse engineering the crossover with a picture from the back of the circiut.

well got 2 replacements of the original tweeters and now they run fine. they don't comply with driving many other different tweeters but with their own Heco tweeters they run just fine!
