The old caps are bad, so we usually choose the "best" cap we can afford, and solder it in the crossovers. I'd opine (FWIW) that there's no good reason to put in lower voltage capacitors than were originally present, but I'll also opine that 200 V rated capacitors shouldn't be a problem at least in the MR and HF sections of a crossover. The brown curve shows the frequency response of the ideal chassis with a 2.7F capacitor in the crossover section of the driver, the red curve shows a capacitance of 12F. The power delivered by the amplifier remains constant. To find power in a resistor use this formula: P=V squared/R. The Supreme is a clear and transparent sounding cap with a good sound stage, providing a good improvement in clarity, focus and dynamics. Example: 300W @ 8ohms WV = sq_root of Watts times the resistance 300 watts x 8 ohms = 2400 sq_root of 2400 = 48.9 volts 48.9 volts x 2 = 98.7 volts The primary figure of merit for a crossover coil is its Quality factor (or Q) for short. L-pads keep the load "seen" by the amplifier constant, affecting only the power delivered to the speaker. Available in values up to 220uF at 400VDC.
