JBL HDI-3600 Crossover Upgrade: Mundorf


Hi guys, I have a new-to-me pair of HDI-3600 and would like to turn a great pair of speakers into a super pair of speakers. Having a look at the stock crossovers, lots of room for improvement, I think JBL could have done a better job frankly given the cost of these - no-name electrolytics (par for the course) and no-name film which appear entry level in the HF.

Question is, moving these caps and resisors to Mundorf options leave me with small variances in values. I am not thinking these variances would make any significant difference, but interested in folks’ opinions.

Here is what I am looking at - replacement value + originating value for both caps and resistors:

Product+value Original Value Application

MCap Supreme
1.8uF(600V) 1.8 HF

MCap Supreme
3.9uF(600V) 4 HF

MCap EVO
22.0uF(450V) 24 HF

MCap MKP (250V)
15.0uF(250V) 15 LF

MCap MKP (250V)
22.0uF(250V) 23 LF

MCap EVO
6.8uF(450V) 6.2 & 6.8 HF & LF

MCap EVO
15.0uF(450V) 14 HF

MR10 Metal-Oxide Film Resistor
2.2Ohm 10W2R4J HF

MR10 Metal-Oxide Film Resistor
3.9 10W4R3J HF

MRES20 MResist Supreme Resistor
10Ohm 25W10RJ HF

 

Any thoughts or wisdom from experience? Notice I am considering vanilla MKP on LF and Supreme/EVOs on HF..

 

Thanks!
