Long time member who has been reading and doing my thing without posting much. Attached is a schemmatic I developed for a CSiA6 from mine. I have had it about a year in anticipation of getting an AV receiver in place of my older stereo receiver. I bought the CSiA6 to go with the older (20 years) RTA 11T towers I have had since new which I modified to RTA 11TL a few years back using the RDO 198 tweeters, Sonic Cap capacitors and Mills resistors. A am now wanting to mod the CSiA6 to more closely match the RTA towers. For those of you that have modded the CSiA6 is what I have correct. I noticed on some of the pictures on the VR3Mods website for the CSiA6 that in either the low pass or high pass section there are actually two resistors instead of one. Is this a modification some are doing to the corssover in addition to replacing the capacitors and resistors?
