I recently picked up a pair of these as a project. Unfortunately, they were missing several of the original components. It seems the crossovers, and L-pads are all functional, but all the drivers that were still there were not wired, so I have no idea how they were wired from the factory. Just to get them working, i used some components i already had, as well as some new ones. I found a similar schematic posted on this site, but it does not seem to be the IIa/r. I have basically wired all the tweeters in series/parallel, wired the mids and woofers the same way. This seemed to make sense, to keep all the drivers in phase, and get equal power to all the components. The more I read on here, the more im sure this was probably not how they were wired originally.
I have not replaced the Passive Radiators yet, but that is coming soon. It is my plan to use the 15" PRs from Parts Express.
I currently have them reassembled and i'm driving them with my Pioneer SX-1250, and it surprises me how much it takes to drive these.
I understand without the Passive Radiators installed, the bass will not be controllable, but these are still in test mode, so still trying to nail down the direction im going.
I have them assembled now using some components i already had, as well as some new ones. I have made some adapter plates to use some tweeters, and a ribbon i acquired, to get these at least functional again
Questions I have, and need advice on.
From what ive seen these are supposed to be 6 OHMs, The way I have them wired, im close to 8, so Schematic needed. I would much rather be at 6
These were pack full of insulation. I mean all the way full. Im assuming from reading other posts, this is too much. How much should i use?
I have seen some diagrams of resistors being used on 2 of the 12s, but not sure what the function of these are, or how to wire them in.
Please help.
Thanks for looking
