@artemus_5 As mentioned above 20 year old capacitors getting long in tooth, should probably replace. As far as I'm concerned electrolytics don't belong in speaker crossovers, the issue is whether film caps will fit, large values mean less likely. Now, I"ve heard very good things about the VH Audio ODAM, not as costly as others and relatively smaller size. Sonic caps are much lower price alternative to the caps I spoke about in previous post.
I'll relate an interesting interaction I had with Bobby Palkovich (RIP) many years ago. Bobby's life work was development of his Merlin line of speakers, constant refinement of original design. Well, naivety lead me to call various manufacturers, designers in those days to report on various mods/substitutions of parts I made to their equipment. So one day I decide to call Bobby and report on Duelund cap mod I had done to my Merlin VSM-MM bam module and internal speaker crossover. Bobby was not too happy with me ( as were other manufacturers I contacted in those days), but showed some interest in spite of this negativity. Lo and behold, perhaps a year later Bobby was offering the Duelund upgrades to his beloved Merlins. It is to Bobby's credit he was open minded enough to hear me through and try my mods on his design. Bobby was already aware of boutique caps prior to my conversation as he was usiing Hovlands at that time, he discovered, as I had the Duelund VSF were an improvement. Many OEM's not as open minded, parts are parts to them, they'll try to convince you the same.
