madrix Posted June 6, 2002 Share Posted June 6, 2002 Recently I replaced my Promedia sattelites with Quintet sattelites for better performance. Ofcourse I had to rework the enclosed crossover by removing the power limiting resistors to match the amplifier signal and power. However there is one problem...I do not know the actual Quintet impedances of the midrange and tweeter speakers so I cannot calculate the new inductor and capacitor values for 120Hz and 4900Hz respectively. Also do you have any idea why the crossovers use bipolar capacitors and which filter order and type they use? Please if you are a crossover expert help me!!

Malcolm Posted June 6, 2002 Share Posted June 6, 2002 Not quite sure why you are doing what yor are. If they won't play loud enough, you just need a bigger amp. If I were you, I would put the resistors back and forget modifying the crossover. IMHO all you are likely to do is screw up the frequency response of the speakers and/or decrease reliability. Bipolar electrolytic capacitors are used in AC circuits, like speakers. Bipolar electrolytics are used instead of other kinds of capacitors primarily because of cost and size considerations.
