I want someone to explain how to go about deciding where a starting point would be for inserting a single capacitor into a system. Would a zobel have to be also done to keep the woofer impedance flat even though there is no x-over for it? A rising impedance will still produce a sound effect wouldnt it ? Due to its affect on the amplifiers output from the load changing ?

Monetarily i cant due what i want right now. (multi amp active x-over ) I tried the single capacitor before but it sounded trash. Most definetly because i was just targeting what i thought were approximate mechanical roll offs for the woofers.:xeye:

I've seen lots of arguments about active crossovers. Seems like you're one of the first to start complaining about it.:D

Only the RCL zobels are normally necessary. The RC zobels really depend on certain design conditions.;)

Why would you want to roll off the with a cap when you have the active XO to do it? You most likely would loss the low end if you put that in series.

I know you probably didnt understand what i said so i will say it again.

I cannot afford to go active right now, and i want to try and reduce the component count in my x-over.

How do i go about getting a starting point ? I dont want to sit play with 500 capacitors and go down or up 50 hz at a time from 3500 to 2200 ... there has to be a way to decide where to start .

This might be a good site to start with. Lots of reading though.
