CSI-A4 Crossover

westmassguy

Need to replace one of the resistors on the crossover for this Center. The existing resistor, R1, overheated and the original printed value is not readable. Anyone have the schematic or can give me the correct value for this part?
Thanks in advance.

I have a CSI-A4 going open it up for 1st time white resistor ? for R1 says: 5W 2(ohm sign i believe )J

hope this helps

R2 says: 5W5.7 * J

Thanks

No problem

I been wanting to open them up and look in there at the crossovers and cap's ect.. to get a better idea of what you all been changing out

The circuit board is pretty tiny. Going to have to move some components to the bottom, and add a riser board

Crossover is completed. New Sonicaps and Mills resistors. Very tight fit, that required relocating the small Bobbin Inductor and both Resistors to the bottom of the board.

NICE!

Think that is over my head! to old, shaky and blind to solder for one thing LOL.

Nice work.

Thanks guys. It's really just like "Paint by Numbers" on these little ones. The problem was fitting the new caps on the board, and the whole crossover fitting back in the speaker. Very limited depth. Most of these Center Channels don't give you much room to play with.

Yep, those Csi A4's are like my Monitor 4's. My 4's have about a 2" hole and the A4's where not much bigger. doesn't give you much room to work with. that is alot of moving around and rethinking the layout.

So WTG again!

Thanks, I just stare at it until I'm cross-eyed, and make it fit.
