Hi,
I hope someone can help with my crossover questions? Specifically, I have original Acoustic Research AR90's, bought directly from the AR factory, when I once worked at a Teledyne company. They're in very good shape. I've refoamed the woofers and the lower midranges. But, the cabinets need a bit of a clean-up, and I'd like to recap the crossovers, being that the speakers are around 35 years old.
Now, my questions. Are certain crossover caps more important in regards to sound than others? Series caps more important than parallel? Tweeters, over mids, over woofers? I want to use decent parts, but I am admittedly on a tight budget. I want to change what counts, using the best that I can afford, and the rest with 'good enough', if there's little sonic impact? Lot's of NPE caps in my 4-way 90's: 4, 6, 8, 24, 40, 30, 80, & 350uf, so I want to budget my money where it'll make the most difference. I'll attach the crossover schematic, for illustration.
Oh yea, the 4, 6, 24, and 80uf caps are the caps wired in series to the drivers. Are they the most important? And should I use only capacitors of the same brand, for consistency in sound? I've looked at Dayton, Audyn, Jantzen, Sonicap Gen 1, Mundorf MCap EVO, and others, but these seem to get consistently good reviews, and aren't 'too' expensive. But, I've been driving myself crazy over this, and just need some guidance, and a 2nd opinion!
Thanks for any suggestions!
