Further crossover tweaks suggested by Eric Chan at Audioreview.com ProAc Response 2.5 comments?
Eric refers to a local Hong Kong audio magazine that suggested the crossover parts of commercial ProAcs be upgraded using higher quality capacitors, inductors and resistors. A lower value 4 ohm series resistor is also suggested on the tweeter, which increases treble intensity. While the use of higher quality parts has merits, the modification of the treble intensity is very system dependant and should be tried with caution. On bright sounding systems or equipment it may not be appropriate. Many builders have already chosen to use premium quality crossover parts (large gauge aircore inductors and tin foil capacitors) and are reporting significant sound improvements, but have not chosen to modify the treble intensity as they feel the treble balance is adequate. However, if you find the treble intensity excessive higher value 8-9 ohm resistors can be used in the tweeter crossover to reduce the intensity.
