[QUOTE="Greg200SE-R, post: 906830, member: 560729"] In a passive crossover for a 2-way component set, is impedance matching ever used? I bought new 6.5" components and this is what my dealer told me about the included passive crossovers: - For the tweeters, the capacitors, inductors and resistors in the XO not only form a 2nd order filter, but also provide impedance matching to help smooth out the natural impedance curve of the tweeter. - If I were to go active w/my system, I should leave the tweeter's caps, coils and resistors inline with it... impedance matching = better sound. - But, if I went active and the tweets were hooked directly up to an amp, the amp would see a more erratic impedance and more resonances would result without the passive XO... worse sound. - Passive components would also provide a fail-safe for the tweeters in case full-range ever hits them. My deck's crossover will still control high-pass frequency. So, how much of this true? My dealer is an electronics grad, but is also a persuasive salesman. Will my tri-amped system sound better if I kept the passive XO for the tweeter? Any input would be appreciated. thanks in advance. Greg [/QUOTE]
