Ya kalo aslinya 22 Ohm diturunkan jadi 6.8 Ohm ya otomatis merubah network-nya jadi tidak ideal lagi donk…
Thanks.

itu gbr 6.8 ohm nya ngaco, hrsnya sesudah 4.2 ohm naro nya.

thanks

Hi Pak Jimmy,

kalo wiring kayaknya tidak ada masalah kelihatannya, maksud sy kepotong itu freq tinggi misal pada cymbal jd tumpul
wiringnya spt ini:

— C 1uF —- R 4.2 ohm ——- + 8 ohm
I
6.8 ohm
I
——————————– –

sperti itu wiringnya, aslinya bagian yang paralel memang pakai 22 ohm, tetapi suaranya memang bright sih, apa yg 6.8 nya saya seri lagi misal + 10 ohm gitu?

Hi Pak,
Kalo nilai sama sih mestinya ga ada penurunan gain ya? Saya ga nangkep maksudnya kepotong bagian atasnya itu gimana? Mungkin ada salah wiring? Sehingga L-Pad-nya menurunkan impedansi tweeter sehingga menggeser cut-off-nya tweeter.
Thanks.

Pak Jimmy, sy barusan coba ganti L pad pd tweeter Fostex T900 pengurangan -7 dB, aslinya sy pakai metal film resistor + dale 5w wirewound, skg sy ganti pakai Duelund yg coklat, capacitor mundorf silver oil – 1st order
Sy tempatkan L pad sesudah cap, tp kok suaranya malah kepotong bagian atasnya ya? Apanya yg salah?sekedar info tweeternya 106 dB + Fostex fullrange FE208ES 99 dB
Mohon pencerahannya. Thx

Hi,
Duelund coba kamu tanya di forum modifikasi. Setau saya ada agennya (tapi saya lupa nama yang jual karena sudah lama ga online ke sana).

Saya sendiri ada stok beberapa value (rasanya 1R dan 3R9 sih ada), tapi biasanya buat dipakai sendiri saja sih (ya kecuali kalo ada kenalan yang butuh banget dan saya kebetulan gak pake, kadang saya share).

Thank you.

halo ko jimmy…
mao tanya, resistor duelund nya brapaan yah harganya?? jauh lebih bagus yah daripada caddock??
saya sebenernya lagi cari resistor caddock / vishay dale 10watt ukuran 1ohm & 3,9ohm..untuk pasif XO di car audio..
saya suda cari ke bbrp org home audio kenalan ko malion tp pada kosong barangnya…..
moga2 ko jimmy mau membantu saya…
tolong emailin saya harga2nya yah ko..

Had tried kiwame, mundorf and sfernice but i like RMG Riken the most so far.

Hi,
Usually I prefer Mills for XO. Some other good candidates are Sfernice, Kiwame, and Duelund.

Thanks.

RMG RIKEN got low ohm at 2w but you need to parrallel them to get higher W, i’m using them in speaker crossover.

Hi,
RMG is different and can’t be compared with Duelund. Basically Duelund is for speaker, so very limited in terms of the resistance value (maybe around 500 Ohm max). While in circuit, 500 Ohm is practically not usable. On the other side, Riken RMG is more popular for circuit application, not speaker. The value is available up to several KOhm.

So it’s gonna be difficult to do the comparison.

Thanks.

Wish to hear your comparison, never the sound of duelend resistor….really wondering how much its differences from RMG as the price is huge different.

Cool. I got myself a pair of these and plan to install them to replace regular duelund resistors in the HF section of my x-over. The colour is interesting, but since the resistors are filled with a dark coloured substance (presume to help damping) I suppose this bleeds into the regular paper tube causing the dark colour. I look forward to your impressions Jimmy.

Where I can buy this one?
thx.

I’m glad they’re smaller, the standard line can be cumbersome. I should be ordering two pairs soon.
