  • For woofers mas makikita sa board mga coils. Kung para sa tweeter mas capacitors po ang installed. Sa midrange eh a mix of both sa design.
  • yung 739 ko maganda naman yung tunog paired with kumyoung singcus 2 and mission 738 speakers....
  • high pass filter is a RCL circuit. you need to compute kung anu magiging cutoff frequency mo.
  • pk explain naman po kung panu mag compute.. sory newbie tlga..
  • one question pa po.. panu ko po i wiwire ung three 8 ohm speaker sa isang channel ng ampli ko.. lets say sa 3 speakers sa left 3 speakers sa right (high-mid-low). dba kung parallel ung tatlong speakers lalabas na 2.6 ohm ung total nila??? ung ampli ko kc sakura 739, tpos 4 - 8 ohms lang ang kaya i handle... dba masunog ampli ko nun???
  • Depende sa connection para masabi kung low pass or high pass filter. Simple example, ang series capacitor ay high pass filter pero pag parallel na connection nya low pass na sya. You can mix RLC pero depende sa config para masabi kung low or high pass. Tapos meron ding bandpass which accepts certain frequency range lang.
  • @projectdimpreza

    Since your configuration is a 3-way system, it is connected something like below and assuming all 3 speakers are 8 ohms the total impedance will still be approximately 8 ohms.

    It is too advanced for a newbie to compute the cutoff frequency so it is better to just buy a 3-way CNB like pictured below and it is better this way. You need to buy 2 of them of course. Just remember don't buy a CNB with a very low power rating.

  • cn3500 will do i think.
  • Somebody know where can i buy Samsung Shape , Sonos Play 1 and 3 and Bose Soundlink III??
  • @ fortoz

    is CNB same as network divider or crossover?? pag nag CNB bko di kona kailangan gawin ung nsa diagram ng 1st pic na post neo? by the way my ampli is 750W and the biggest speaker i have is 500W what CNB do i need? 750W higher? or 500W higher? saan po ba mag base? sa ampli or sa speaker?

    @ron1221

    sa crown kc may CN-3600 600w dividing network.. or cn500 nlng tulad ng sinabe neo?
  • anu ba ang amp mo? madaling sabihin na 750w. kasi pede ko sabihin na meron akong 10000w na amp. hehehe

    inuulit ko po wag maniniwala sa rating na nakasulat sa likod ng amp. get the secondary voltage and the capacity of transformer and do the math.
  • @ ron1221

    Sakura av-739 po amp ko.
  • mga sir...help po sa sound and videoke setup ko po kung pano ko po mapapaganda pa ang tunog nag setup ko plss.
    amp konzert 502b
    spk konzert ks650v
    videoke player karavision k12

  • is CNB same as network divider or crossover??


    Yes they are the same.

    pag nag CNB bko di kona kailangan gawin ung nsa diagram ng 1st pic


    That diagram is only a sample which is actually from a CNB :) When you buy a CNB it will be like that with only the parts count and values different depending the manufacturer.

    saan po ba mag base? sa ampli or sa speaker?


    Based on the amp's rated power in RMS.
  • how to get RMS?
  • Update:

    i end up getting Crown CN-3500. 500W 3way 800Hz & 4Khz 12dB octave slope. tinesting dun sa binilhan ko.. mahina ung tunog nia.. sbe nun nag testing kc mababa lang dw ung ampli na ginamit nia.. ok dw cia kung sa ampli ko na 750W gagamitin..

    Di kopa na test ulit dto sa bahay.. mejo kulang na kc sa oras.. pero kung mahina pdin cia.. panu kaya gagawin ko?
  • itest mo muna. yung isang ch may cnb yung isa wala. tingnan mo kung mahina talaga
  • update again::

    ka tetest ko lang po.. using my ampli.. malakas naman pla.. di ko pa lang ma taasan ung volume kc gabi na po hehe.. pero tingin ko malakas nga cia.. in my opinion sa ampli nga cguro nagkatalo kaya mahina nun tenesting dun sa binilhan ko..

    isa nlng po ang worry ko.. 500W kc ung CNB. 750W ung ampli ayon sa nka sulat sa likod ng ampli.. di ko kc alam kung pano kunin RMS.. pero hinihipo ko naman ung CNB ska ung ampli pti ndin speakers kung nag iinit.. pero cool lang naman sila.. sna tumagal pag babaran...
  • Hi po,
    Ask lang po sana mga Sir. Nag-install kasi ako ng volume control sa videoke machine ko po eh ipinagtataka ko lang yun tweeter lang po ang gumagana when i turned on the videoke. When i used another untouched RCA cable naman ok na ok po ang sound. Ang setup ko po pala ay platinum X5, konzert 502b. Is there something wrong with my wiring kaya?
    Image below shows my connection exactly,

  • btw, i used 100k dual pot po pala.Thanks po in advance.
  • The wiring appears to be in order naman. Better check for possible breach in one of the cables connected.
  • okay lang yan. hindi tunay na 750w yan. nasa 150-200w rms lang yan.
  • ok salamat sa advise sir ron..

    one more question.. can you put Left & Right speakers in one box enclosure? pwede ba pagsamahin sila sa isang kahon without any division inside..? let say woofer or sub..
  • one more question.. can you put Left & Right speakers in one box enclosure? pwede ba pagsamahin sila sa isang kahon without any division inside..? let say woofer or sub..

    Ahahaha... eh kung yan po ba ang trip nyo eh. Huwag kayo magtataka kung bakit walang stereo separation ang maririnig nyo kasi mistulang MONO po ang spatial effect niyan. Hindi maghihiwalay ang sound na stereo kapag ganyan kasi nasa iisang bbox lahat ng speakers kamo. Kahit man lang sana yun left and right nasa one side of the enclosure at magkahiwalay. But of course wala masama pagsamahain at hindi masisira dahil yun stereo effect lamang ang affected. Tsk Tsk.
  • one more question.. can you put Left & Right speakers in one box enclosure? pwede ba pagsamahin sila sa isang kahon without any division inside..? let say woofer or sub..

    pwede sir basta may division yung L/R subs. maghahatakan kasi sila kung stereo ang source mo. pero kung mono ang source mo, kahit walang division na yung sub box mo.

    ang subwoofer naman, di na kailangan ng stereo separation. lalo na kung mono ang source (I.e Subwoofer output ng receiver) just place it in one corner, it will do it's job na.

    pero kung gusto mo talaga ilagay sa isang box enclosure yung mga speakers mo, try mo design ng mga sound bars, nasa isang box, pero may stereo separation parin. you can use a 6" woofer, and a 1" tweeter on each side then, separate box mo nalang yung sub mo.
  • ahh ganun po ba.. stereo kc ung output ng ampli ko..

    pwede kaya na dlawang woofer ang nka kabit sa isang crossover board? pra di kona lalagyan ng division ung box? bale mababakante ung woofer output ng isang crossover board ko.. kc ung dlwang woofer dun sa isang crossover board nka kabit?? ok lang po kaya un?
  • One mono crossover board per channel. Period.
