Was a tough and tiring Friday. I want to listen some music (but I need to tweak some). Ok, fire up my iron and start to cook it right away.

If you don’t have any idea about my DIY speaker, feel free to visit here and here.

Ok, basically I just add 0.47uF K40Y-9 capacitor on my high pass filter. Current configuration is a little bit too bright on the tweeter, so I need to lower the F3 of my high pass filter. So here it is…

The high pass is 2rd order, combination of Siemens PIO and K40Y-9. Also Sfernice resistor used there. The inductor is Alpha Core Foil Inductor. Bought it few years ago, not the price is getting high and higher!

Just another shoot from another other side.

Poor’s man system. A hi-fi amplifier with “tweaked” iPod as source. Oh and an big bowl of instant noodle as dinner ;) It sounds (and tastes) good!

    Desain crossover tergantung speaker Anda sendiri Pak.
    Komponen cukup beragam, ada Alpha Core, Auricap (saya ganti), Siemens, K40Y-9, Solen, Sfernice, Eagle, etc.

    Thanks.

    Thanks bro,
    Cuman buat iseng aja koq. Sejauh ini iPod bukan main source saya. Ada rencana bikin DIY LOD-nya untuk bypass dari DAC langsung. Tapi sayang juga lah, ntar output headphone-nya mesti didisable. Kalo pake LOD di pasaran sih suaranya saya uda coba. Biasa aja tuh.

    mantep deh bang… eh, btw kalo ngga salah LOD itu kan ngebypass internal ampli ya bang jim, outputnya tetep audio analog kan ya? kalo ngebypas DAC berarti outputnya bitstream digital gitu ya? kayak wadia itransport nya bang jim ya? wuih manteb banget deh…



  8. Jimmy Auw Says:

    Maksud saya ngebypass langsung dari keluaran dari DAC-nya… bukan DAC-nya yang dibypass…

    Kalo LOD umum yang dijual di pasaran tetep lewat jalur internalnya (seperti pengaturan volume, dsb). Sehingga tetep aja ga murni.

    Thanks.

    Hi,
    Desain box tergantung driver-nya, tidak ada yang universal.
    Thanks.

    Hi,
    Skema-nya saya sudah tidak ingat karena sudah dirubah beberapa kali. Mesti bongkar speakernya dulu.
    Thanks.
