[QUOTE="maylar, post: 8269592, member: 541144"] You will need an amp for the tweeters with a crossover that covers the 3.5 Khz range, which is where the Kappas are crossed with the passive crossovers. I wouldn't bother using a lowpass for the mids, just the hipass built into whatever amp you use. You only need maybe 25 watts for the tweeters. No need to go big on that. You could use a PPI 900.4 for the front stage, it has a hipass filter that covers the tweeter range but that would be way overkill. But... if it were me... Before going through the effort and expense I would try other things to tame the tweeters. Relocating them or even turning them off axis could help. Sometimes reversing the polarity on one or the other or both can make it better. Be aware that the aluminum Kappa tweeters are notoriously bright and harsh. If you're going to change speakers anyway I would do that first before attempting an active solution. [/QUOTE]
