Your calculations look correct. Those caps are too big though. IIRC the lead spacing on the board is 5mm
Your cap values indicate a crossoverpoint at 1k according to MR's app: (http://doublesecretlabs.com/apps/passxo/)I'm trying to put together a DigiKey order and am a bit stumped on the C & C/2 caps. My target crossover point is 650 hz and I have calculated C = 9.231 (10) nF = .010 mF = 10,000 pF and C/2 = 4.615 nF = .0047 mF = 4,700 pF.
Should have just jumped right in instead of pouring that second cup of coffee...LOLtoo late again...
Hi Attila -you have to adjust P1 & P2 (0-50k) to your calculations (including the 10k resistors)
just play with the app until you get the slopes right (thats what i did)
e.g. my slob results
Hey Jim,Hi Attila -
I like your values here. Question: Where did you source 24nf and 23nf film capacitors?
Thanks very much,
Jim
My understanding of these is now only slightly less miniscule
