![]() I removed all the “tiny-little-cute” capacitor from the board. The components are: 4.7 uF, 6.8 uF, 47 uF, 0.8 mH, and 0.25 mH.īelow is just another view of the stock crossover. Need to fire up my simulator to check the actual graphs, but since I think this is just for fun, I don’t sweat a lot □ ![]() I think they build a bandpass filter and both woofer works in different region. The two mid woofer is not working on same region. They use 1st order for high pass section, F3 at around 8 kHz I think (if I calculate them correctly). Also you can find small inductor with ferrite. The internal crossover uses “bad” non-polar eletrolytic. I think it’s good enough for most people, but not for me □ Need to be improved a little bit in the low bass region. I think the subwoofer is for movie (THX Certified) than music. This system has a little bit bright sound, metallic, a little bit harsh, not too detail for music, and average mid. ![]() Anyway, since this is just for fun, so let’s do it. It’s quite challenging for me, since you know that I don’t (never) expect much from a multimedia based computer (some of them are good, but not good enough for my taste). The target of this mod should fulfill 3 main criterias: I think so far MX5021 is one of good candidate to be modded (though I prefer Altec CS21 or 621/641 series, but they have been discontinued).
