Speaker crossover mod. Your advice?
I have removed the crossover from the speaker. Here is a link to the photos I took: Focal 1027 crossover I don't really know how to interpret what I'm seeing. Any help would be greatly appreciated. Bryon |
You may want to consider starting from 'scratch'. Get a schematic even if you have to start tracing wires around..... That board has (GASP!) 5 iron core inductors. In the Magnepan world of DIY, that is one of the first things to go.....change the iron core to an AIRcore inductor to eliminate possibilities of saturation. Any series resistance changes can be made up using lower or higher resistor values. Gotta have the schematic, first, though. Start tracing where the wires come TO the board from the amp. Also, any new caps are likely larger than stock. It just seems to work out that way. |
Bryon, help us help you by tracing a schematic diagram of all sections of the x-over. It's really easy to tell you to replace all the film caps with other expensive film caps, but that does no one except the cap seller any good. If you think that's beyond your capability, get someone else to do it. I find it easier to start with the output sections, not the inputs. Since the output wires are clearly labeled, you have a head-start on the project. . |
You can try another (more expensive ) cap as long as it has the same value and has the appropriate voltage of the focal one . More expensive isnt always much better though and ive tried a lot believe me , duelund being the rolls royce of caps. If you dont replace the same value you will change the intendid balance of the speaker. I dont think there will be any manufacturer guarantee either. mundorf is also good stuff , i use a silver / oil at the moment with the diamond tweeter . |
