Hi all,
I was given this site by Xristo on Car Audio Australia, who said you might be able to help me out
I'm looking at upgrading my car audio system with a new front stage. 8inch morel Hybrid mid/woofers, coupled with a pair of Arvus (TBC) tweeters. These will be going into my BMW E32 7-series, and driven from an Eclipse EA3422 Amp bridged into each channel.
I have a set of Canton Pullman RS3.22 3-way passive crossovers, that I'm trying to dissassemble and make a 2-way crossover for a 8inch Morel and a tweeter (Yet to be decided).
I spent some time trying to document the crossover circuit layout and have come up with a layout I'll put up very soon. I'm a little unsure of some areas of the crossover layout, values, and thier purpose though.
The main section that has me confused, aside from the component value's of the inductors is the tiny ceramic cap, and 12ohm 10W wirewound resistor section that feeds the tweeter output. The tweeter section appears to be 12dB high pass (w/attentuation) which is fine, but the small ceramic is in series with the pos feed?
The mid seems okay, with a 6dB high pass and 12dB low pass.
The woofer again being a 12dB low pass.
I'm thinking I should just be able to drop the 6dB high pass from the mid section and use that as my mid/woofer output?
Can anyone see any potential issues I may be overlooking here?
I'm also tempted to put a polyswitch in line with the tweeter for protection(Thanks for the advice Jason) but can't seem to find one that will trigger around 120WRMS?

Sorry for the long post....
Thanks in advance...
